  • Fix an error caused by attempting to use the Edit > Cut command when there is only one node.

New in TreeLine 3.0.0 (Aug 20, 2018)

  • Notes:
  • This is the first stable release of a major TreeLine rewrite. It includes all of the new features shown below in the 2.1.x and 2.9.x development series.
  • TreeLine files now use a JSON format in place of the old XML format. This provides more flexibility for structuring new features like cloned nodes and multiple root nodes. A new file extension (".trln) helps to distinguish files with the new format. Import and export filters are provided for older TreeLine version 2.x and 1.x files. The older files can be opened using the standard "File > Open" command.
  • A GUI translations is available in German. All other translations are out of date and have not been included. Volunteers are needed to update translations in several languages.
  • New Features:
  • The default font for the application can now be set in Tools > Customize Fonts. This is useful for enlarging fonts on some systems with high screen resolutions. Options still exist to individually specify tree view, output view and editor fonts.
  • Updates:
  • The Windows binary is now built using updated libraries (Qt 5.11 and PyQt 5.11).

New in TreeLine 2.9.2 Development Snapshot (Jul 1, 2018)

  • Updates:
  • The German GUI translation was updated (thanks to Maria Seliger).
  • The expand/collapse status of nearby nodes is maintained while editing the node structure. This includes adding, deleting, moving and indenting nodes.
  • The expanded/collapsed and selected tree states are now saved even if changes were discarded in the previous session.
  • A click on a tree node to restore tree focus no longer starts editing the node title.
  • The enter key now selects a tree node after the first title letter(s) are typed to make it current (shown with a box around the title).
  • Bug Fixes:
  • Several errors occurring when deleting or removing nodes have been fixed. These include problems when the mouse is pre-highlighting descendant nodes and when nodes to be deleted are selected in a separate window.
  • Fixed node title editing errors caused by moving the mouse to a data edit box with the title edit still active.
  • Fixed errors occurring when field types are changed after initial default values have been set.

New in TreeLine 2.9.1 Development Snapshot (Mar 31, 2018)

  • Notes:
  • This is an unstable development snapshot of TreeLine. It has improved but could still contain bugs. Testing and bug reports are appreciated, but those with very critical work should consider using the stable release (TreeLine 2.0.x).
  • This is a major rewrite of TreeLine. Once it becomes more stable, it will be released as TreeLine version 3.0.0. The 2.1.x unstable series is being discontinued (no stable 2.2.0 release is planned).
  • The GUI and documentation translations are out of date and have not been included. Volunteers are needed to update translations in several languages.
  • New Features:
  • A new HTML export uses Javascript and CSS to create a live tree view. Nodes in the tree can be expanded and collapsed, and a separate pane shows the output for all descendants of the selected node. One form of this export creates separate files that are linked to the existing TreeLine file. These files are intended for use on a web server (browser security usually prevents local access). Only the TreeLine file needs to be replaced to update the data (re-export is not required). The second form creates a single file (with embedded data) that can be accessed from a local web browser.
  • New forms of CSV table text imports and exports can work with multiple levels of child nodes, preserving the tree structure. The first column of the table includes a level number that is incremented for child relationships.
  • Added a custom time select dialog box for editing Time and TimeDate fields.
  • A new general option controls whether inaccessible files are removed from the recent file list at startup. The files are removed by default, but this can be changed to avoid losing listings of files stored on removable drives.
  • Bug Fixes:
  • Fix errors shown when using copy commands after closing TreeLine windows.
  • Fixed problems with copy / paste and drag / drop on nodes with conditional type settings.
  • Avoid problems showing the tree view after closing a filter command that found no matches.
  • Fixed issues on Windows with pull-down combo boxes not working after repeatedly showing some dialogs (mostly find and filter dialogs).
  • Fixed problems with generic XML export from multiple root nodes.
  • Fixed problems with number field formatting when using a "," radix with exponents.
  • Avoid issues resolving relative paths between different Windows drive letters in external link fields.
  • Fixed problems with advanced ancestor field output references in some tree locations.
  • Properly update the right-hand views after using a new window command.
  • Avoid problems running data category-based commands on selections without any child nodes.
  • Fixed minor spacing issues for tables shown in output views and HTML exports.

New in TreeLine 2.9.0 Development Snapshot (Jan 29, 2018)

  • New Features:
  • TreeLine files now uses a new JSON format in place of the old XML format. This provides more flexibility for structuring new features like cloned nodes and multiple root nodes. A new file extension (".trln) helps to distinguish these files.
  • Import and export filters are provided for older TreeLine version 2.x and 1.x files. The older files can be opened using the standard "File > Open" command.
  • Multiple top-level (root) nodes are now permitted. When no nodes are selected in the tree (by clicking on a blank area or Ctrl clicking to unselect), the right-hand view will show information about all of the top-level nodes.
  • A new breadcrumb view pane above the other panes shows a sequence of ancestor titles for a selected node. The ancestors can be clicked to select them. For cloned nodes, multiple lines provide links to each instance's ancestor sequence.
  • By default, the edit boxes in the data edit view now activate when the mouse hovers over them. This eliminates the need to click to activate them. This feature can be disabled in general options if desired.
  • When a file is opened in an existing window, the window is now reused (not just replaced) to eliminate flashing.
  • Cloned nodes now have a more native and efficient implementation. This allows the same nodes to have multiple parents. The new breadcrumb view shows a list of clones for the selected node that can be clicked to select the other instances.
  • New paste commands have been added for adding nodes before and after siblings. There are also multiple paste commands for adding clones of nodes.
  • Cloned nodes can be created automatically from all identical nodes by using the "Data > Clone All Matched Nodes" command.
  • The new "Data > Detach Clones" command converts cloned nodes in selected branches back into independent nodes.
  • A new "Swap Category Levels" command swaps child and grandchild nodes beneath a selected node. A child node with multiple nodes under it will become cloned under each one. Any existing grandchild clones will become individual nodes with multiple children.
  • Child node types that are available to be set can be limited. A new pull-down list of child type limits is in the "Type Config" tab of the configuration dialog if the advanced functions are shown.
  • The Date, Time and DateTime fields have new format strings that enable extra text to be added to the date output.
  • To improve efficiency, user visible node unique IDs that depend on the node's data have been removed.
  • Error handling has been improved. For most errors, a dialog box is shown with debugging information that can be copied into an email.
  • Added a desktop specification file to the Linux installer for desktop environment menu support.

New in TreeLine 2.1.2 Development Snapshot (Mar 29, 2017)

  • Notes:
  • This is an unstable development snapshot of TreeLine. It may contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 2.0.x) should probably be used for critical work.
  • The GUI and documentation translations have not yet been updated.
  • Bug Fixes:
  • Fix problems formatting DateTime fields in output views.
  • Fix dialog issues with clicking on targets when creating inline internal links.
  • Fix a regression that prevented using the tab key to cycle between data edit view items.
  • Avoid opening two windows when restoring an auto-saved backup file.

New in TreeLine 2.1.1 Development Snapshot (Mar 13, 2017)

  • Notes:
  • This is an unstable development snapshot of TreeLine. It may contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 2.0.x) should probably be used for critical work.
  • The GUI and documentation translations have not yet been updated.
  • Updates:
  • The Windows binary is now built using Python 3.6 and PyQt 5.8.
  • Bug Fixes:
  • Fix a crash when changing the icon on the Type Config page of the Configure Data Types dialog box.
  • Fix inconsistent type selections on the Type List page of the Configure Data Types dialog box.
  • Fix issues with restoring the placement of the TreeLine window in some multiple monitor setups.

New in TreeLine 2.1.0 Development Snapshot (Feb 21, 2017)

  • New Features:
  • TreeLine has been ported from the Qt4 library to the Qt5 library. The system requirements have been updated to Python 3.4 or higher, PyQt 5.4 or higher and Qt 5.4 or higher.
  • Cloned nodes that can duplicate sections of the tree have been added. Editing their data or child structure in one location changes all locations. They are created by copying nodes and then using the "Edit->Paste Cloned Node" command to paste them elsewhere. The clone link can be removed by deleting the nodes or by cutting them and pasting them back using the regular paste command.
  • Added a new DateTime field that combines dates and times into a single field that is useful for timestamps. The editor format is a combination of the date and time formats from the general options, separated by a space.
  • Added an option to allow HTML tags in Choice, AutoChoice, Combination, AutoCombination and RegularExpression fields. The control is in the Field Config tab of the Configure Data Types dialog. This option is disabled by default. If enabled, special characters (angled brackets and quotation marks) will need to be escaped to show up in text.
  • Saved rules for Conditional Find and Conditional Filter commands are listed directly in the dialog boxes, making them easier to load and save.
  • Added comma-delimited (CSV) table import and export, similar to existing tab-delimited table import and export. The export only handles data from a single level of child nodes.
  • Added a quick, incremental search of node titles. By default, it's bound to ctrl+/. Then, matching titles are found as the search string is typed. The F3 and shift+F3 keys can be used to go to the next or previous matches, respectively.
  • Multiple fields can now be selected in the Output page of the Configuration dialog, so several fields can be added to the formats simultaneously.
  • A pull-down selector for printers has been added to the Print Setup dialog. This enables TreeLine to verify that the page size and margin settings are supported by the current printer.
  • Updates:
  • The SpacedText Field now allows special HTML characters (angled brackets and quotation marks) without requiring them to be manually escaped.
  • Bug Fixes:
  • The code that splits content into pages when printing has been improved. It now handles very long nodes better.
  • When formatted fields (dates, times, etc.) are used in node titles, editing the titles in the tree or in the Title List pane will now work if the edit and output formats are similar.

New in TreeLine 2.0.2 (Oct 4, 2015)

  • Fixed a major regression in 2.0.1 that broke data editors for most specialized field types (number, math, boolean, choice, etc.)

New in TreeLine 2.0.1 (Sep 28, 2015)

  • Updates:
  • Added methods to the plugin interface that allow general program options to be queried and changed.
  • Improve text table import error messages by including the line number where the problem is found.
  • Bug Fixes:
  • Reduce the amount of work that a single undo command removes from editors in the data edit view.
  • Fixed a bug that prevented setting the unique ID reference field on a newly created data type.
  • Preserve hard newlines in text fields when converting TreeLine 1.4.x files to this version.
  • Fix problems preserving expand/collapse node states when indenting and unindenting nodes.
  • Compatibility Notes:
  • There are some file format changes between TreeLine 1.4.x and this version of TreeLine.
  • Older files opened in this version are automatically converted when saved.
  • Files saved in this version may not be fully compatible with TreeLine 1.4.x.

New in TreeLine 2.0.0 (May 19, 2015)

  • Updates:
  • Modified the Treepad file import to use SpacedText fields to more closely match Treepad formatting.
  • An optional plugin was written that can export files to the Treepad text file format.
  • The TreeLine icon was replaced with a new one. Thanks to David Reimer for contributing the artwork.
  • The German and Portuguese GUI translations were updated.
  • Updated the long text sample file to include the SpacedText field type, and added a conditional equation to the math sample file.
  • Updated the Math Field section of the documentation.
  • Compatibility Notes:
  • There are some file format changes between TreeLine 1.4.x and this version of TreeLine.
  • Older files opened in this version are automatically converted when saved.
  • Files saved in this version may not be fully compatible with TreeLine 1.4.x.

New in TreeLine 1.9.7 Unstable (Mar 30, 2015)

  • New Features:
  • Added comparison operators and conditional if statements to math field equations. The operators can be used with a new boolean result type, or as a part of numeric, date, time or text expressions.
  • Text operators were made available in math field equations, and the result type can be set to text. This allows math fields to combine text from other fields, replace substrings and change capitalization.
  • Updates:
  • Added a "file saved" status bar message.
  • Added a German GUI translation.
  • Updated the Portuguese GUI translation.
  • Bug Fixes:
  • Fixed a focus problem that made Combination and AutoCombination field editor pull-downs unusable.
  • Fixed a focus problem that made the pull-downs in choice and boolean field editors unusable on Linux.
  • Compatibility Notes:
  • There are some file format changes between TreeLine 1.4.x and this version of TreeLine.
  • Older files opened in this version are automatically converted when saved.
  • Files saved in this version may not be fully compatible with TreeLine 1.4.x.

New in TreeLine 1.9.6 Unstable (Mar 11, 2015)

  • New Features:
  • Added a new OneLineText field type that restricts the text length to a single line.
  • Added an All Types option to the conditional find and filter commands. This allows multiple node types to be found or filtered at the same time. The fields from every type are available for use in conditions. The conditions give a false result for all node types that do not contain that field name.
  • Added support for date and time calculations using math fields. Math equation result types can be set to numeric, date or time output. Date fields can be subtracted to give the number of days elapsed, and numbers of days can be added to or subtracted from dates, resulting in new dates. Time fields can be subtracted to give the number of seconds elapsed, and numbers of seconds can be added to or subtracted from times, resulting in new times.
  • In math fields, added an equation reference level to reference fields in the root node. This provides a place for "constant" field values that can be referenced from any node but only need to be changed in one location.
  • Support was added for plugin extension modules. Most of the interface methods from TreeLine 1.4.x were duplicated to ease porting of old plugins. Of course, old plugins must be ported from Python 2.x to Python 3.x, and there are multi-window implementation differences. New interfaces allow the creation of new field types and the execution of any menu command. Sample plugins are available on the TreeLine download page.
  • Added text formatting and link commands for HTML fields that add tags to the HTML content.
  • An open in folder command was added to external link field editors to open the directory in a file manager.
  • Added the Select All command to global menus with a different default shortcut key (ctrl-L) to avoid conflicts with the add child shortcut.
  • Updates:
  • Improved the focus handling for data edit view edit boxes. This eliminates the blue outline for boxes in inactive data edit views. It also makes tab-to-focus more predictable, including fully selecting single-line field types when they receive tab focus.
  • Data edit boxes are now automatically resized when editing is complete and the focus moves to another row.
  • Allow files to be drag & dropped on data edit boxes to create external links.
  • Small, non-modal dialogs, such as those for sorting, numbering, finding and filtering, have been set to stay on top, so they won't be obscured by TreeLine windows.
  • Made opening associated programs from external file links more consistent, especially in Linux.
  • The copy types from file command now supports encrypted and compressed files.
  • Added wait cursors to TreeLine operations that could be time consuming.
  • Improved the consistency of context menus and shortcut commands used in edit boxes.
  • Added a nearly complete Portuguese GUI translation.
  • Added support for sample TreeLine files to be provided in alternate languages.
  • Prepared the help file for translation into other languages,
  • Bug Fixes:
  • Corrupted TreeLine files with the same unique ID assigned to multiple nodes no longer fail to open. The user is warned that unique IDs have been updated, which could break some internal links.
  • Fixed missing fields in the pull-down list in the conditional find and filter dialog boxes when a rule was re-used after a node type change.
  • Fixed problems with math fields that reference non-existing fields in parent or child nodes.
  • Made math fields update properly after node type changes.
  • Fixed inconsistent updates after renaming fields used with bulleted or tabled output.
  • Made node copy-paste and drag-and-drop work when the initial selection includes both parent and child nodes.
  • When importing a tabbed text file with multiple top-level nodes, create a single higher-level node to prevent failure.
  • Fixed the availability of the move up button in the customize toolbar dialog when the second command in the list is selected.

New in TreeLine 1.9.5 Unstable (Jan 6, 2015)

  • New Features:
  • Added a math field type that is configured by defining an equation. The field value is automatically calculated based on references to numerical values in other nodes. See the "sample_math_fields" file for a usage example.
  • Added a Clear Formatting command that removes font changes and links from data editor text.
  • Made source code changes necessary to support user interface translations into other languages. The actual translation work remains to be done.
  • Updates:
  • Add scroll bars to the pull-down editors for combination fields with many entries.
  • Reduce the truncation of external link URLs when generating default display names.
  • Use Unix-style newlines for saved TreeLine files to keep files consistent across platforms.
  • Update the CSS code in exported HTML with navigation panes to improve the appearance in some browsers.
  • Optimize some undo information to reduce the amount of data in memory.
  • Move sample files into a separate directory to avoid future translation conflicts.
  • Clarify a Linux installer error message when checking for the Python 3 version of PyQt.
  • Include MSVCR DLL files in the Windows installer.
  • Bug Fixes:
  • Fix problems applying multiple configuration changes while the Configure Data Types dialog box remains open.
  • In the Title List editor, splitting a title into two lines now creates a new node without losing the children and parameters of the original node.
  • Fix the undo command in the Title List View so that deleted lines/nodes are properly restored.
  • When sorting nodes by fields, properly handle a reverse direction.
  • Fix problems with the find and replace command when a particular node type is specified.
  • Fix problems defining conditional types from the Configure Data Types dialog box.
  • Correctly apply font size formatting to selections with mixed font sizes.
  • Fix the height of long text field editors with customized data editor fonts.
  • Fix HTML export of Base 64 images.

New in TreeLine 1.9.4 Unstable (Mar 10, 2014)

  • New Features:
  • Created new documentation, including a TreeLine file with details and a text file with basic usage instructions. Both are accessible from the help menu.
  • Added customizing of default fonts used in the tree, output and editor views.
  • Added a new SpacedText field type that holds plain text and preserves all spacing.
  • Combination and auto combination field types now use a simpler checkbox style pull-down editor.
  • An autosave option was added.
  • A unique ID reference field was added to the file info fields to allow node unique IDs to be included in output formats.
  • A plain text paste command was added to paste non-formatted text to data editors.
  • Added an option to set the child indent offset amount.
  • Updates:
  • The last size and position of the print preview window are remembered and restored.
  • When printing, nodes with long text content are split between pages.
  • In multiple page HTML exports, relative links in the content are adjusted based on the directory depth.
  • Bug Fixes:
  • Fixed problems outputting completely blank nodes.
  • Problems with the contains and true/false conditional rules were fixed.
  • Fixed issues displaying several editor link dialogs in quick succession.
  • In the configure data types dialog, the output format cursor no longer moves when switching to other field references.
  • Compatibility Notes:
  • There are some file format changes between TreeLine 1.4.x and this version of TreeLine.
  • Older files opened in this version are automatically converted when saved.
  • Files saved in this version may not be fully compatible with TreeLine 1.4.x.

New in TreeLine 1.9.2 Unstable (Oct 22, 2013)

  • Notes:
  • This is an unstable development snapshot of a full rewrite of TreeLine. It is not feature complete and probably contains bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.4.x) should be used for critical work.
  • The documentation is not included yet. It needs to be updated to cover the new features.
  • The GUI and documentation translations have not yet been done.
  • New Features:
  • Added a spell check tool. This requires either aspell, ispell or hunspell to be installed.
  • Included a node numbering field type with several formatting options. An update numbering command fills in the sequence.
  • Added a command to add a category level based on a subset of data fields.
  • Added a flatten by category command to combine parent fields into child nodes.

New in TreeLine 1.9.1 Unstable (May 2, 2013)

  • Updates:
  • Added TreeLine file compression and file encryption, controlled from a File > Properties dialog box.
  • Tree node open/close states are restored for recent files.
  • Added derived data types that keep the field list of their generic type.
  • Added conditional type setting that changes icons or output format based on field contents.
  • Other field references (file info, ancestors, children) can be used in node output formats and in print headers & footers.
  • Added an HTML file export to a single file with a navigation pane on the side.
  • Allow embedded blank lines in non-HTML node output formats.
  • Added an output separator config option for combination fields and child references.

New in TreeLine 1.3.2 Unstable (May 15, 2010)

  • Notes:
  • This is an unstable development snapshot. It may contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.2.x) should be used for critical work.
  • The GUI and documentation translations have not yet been updated.
  • Updates:
  • Updated the ReadMe file to cover the new features added during this development cycle.
  • Bug Fixes:

New in TreeLine 1.3.1 Unstable (Apr 29, 2010)

  • Notes:
  • This is an unstable development snapshot. It may contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.2.x) should be used for critical work.
  • The documentation has not yet been updated to cover the new features.
  • The GUI and documentation translations have not yet been updated.
  • New Features:

New in TreeLine 1.3.0 Unstable (Jan 17, 2010)

  • Notes: This is an unstable development snapshot. It is not feature complete and probably contains bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.2.x) should be used for critical work.
  • The documentation has not yet been updated to cover the new features.
  • The GUI and documentation translations have not yet been updated.
  • New Features: Multiple TreeLine windows with different files can be open within the same TreeLine session. The "Open files in new windows" general option controls whether new windows are used when opening or creating files.
  • A "Window" menu has been added with commands to create new windows, close windows, or select from a list of current windows.
  • The "Window->New Window" command creates a new window with views of the same TreeLine file. Changes in either window are saved in the same document. This can be used to work in different sections of the file simultaneously. For performance reasons, the non-active window does not show the changes made in the active window until the non-active window is focused.
  • Starting TreeLine (from a shortcut, file association or command line) will activate an existing TreeLine session if it is already running. A new window will be opened if an unopened file was specified by file association or in the command line.
  • An "Add internal link" context menu has been added to text boxes in the data editor. It prompts for another node to be clicked with the mouse, then an inline internal link is added with that node's reference information.
  • Added an "HTML directory pages" export option. This will export to a directory structure with an HTML file for every node. A navigation pane on the left side of each page contains links to the node's parent, uncles and children.
  • Updates: The general options dialog has been split into three columns for better viewing on small, wide displays.
  • Additional export commands and export options have been added to the plugin interface.
  • To avoid a problem on the Mac platform, when TreeLine is run for the first time, it lets the OS determine the window position.

New in TreeLine 1.2.4 Stable (Jan 17, 2010)

  • Bug Fixes: Added a work-around for a bug in PyQt 4.6's clipboard support that can prevent TreeLine from starting.
  • Prevent an uncommanded horizontal scrolling to the left of the tree view when changing the selection.

New in TreeLine 1.2.3 Stable (Jan 17, 2010)

  • Updates: A new build has been created for use on the Windows 98 operating system. This fixes problems that made TreeLine 1.2.2 unusable on Windows 98.
  • Data copied to the Windows clipboard is now preserved after exiting from TreeLine.
  • Bug Fixes: Fixed a bug on Windows that showed an error message at program exit if the copy command had been used during the session.
  • In an HTML directories export, characters that are illegal in directory names are now correctly removed.

New in TreeLine 1.2.2 Stable (Jan 17, 2010)

  • Updates: Added German translations of the GUI and the ReadMe file.
  • Added a few missing strings to the translation files.
  • Substituted some imported modules to avoid deprecation warnings in Python 2.6. Note that Python 2.3 is no longer supported.
  • The windows binary has been updated to use Python 2.6, and the installer has been tweaked to reduce DLL conflicts.
  • Bug Fixes: Fixed problems using the tab key to change focus from the tree to the data editor.
  • ID numbers are now properly assigned to new nodes with UniqueID fields in the title.
  • Fixed problems creating nodes with child count fields in the titles.

  • Problems with opening files with Unicode file names from the command line or from a file association have been fixed.
  • Fixed problems with JPEG and GIF image support in the Windows binary build.
  • When commands change the tree view, it no longer scrolls vertically unless the current node is not visible.
  • Fixed problems with files set to both compressed and encrypted modes. But note that compressing an encrypted file still does not significantly reduce its size.
  • Problems on the Macintosh platform with detecting the text encoding and with setting the default theme have been fixed.

New in TreeLine 1.2.0 Stable (Jan 17, 2010)

  • Notes: This is a new stable release, ending the 1.1.x development series.
  • This release is only available in English and French. The 1.0.2 release is still available, including German, Portuguese, Russian and Spanish translations. Volunteers to update the translations are welcome.
  • Updates: The French translations of the GUI and the ReadMe file have been updated.
  • Bug Fixes: When restoring an auto-saved backup file, TreeLine no longer replaces a the main file with the backup if the backup is not a valid TreeLine file.
  • Fixed a minor bug in the Configure Data Types dialog caused by unselecting a field in the Output pane.
  • Major New Features Since 1.0.x: TreeLine was extensively rewritten to port it to the Qt4 library (previous versions used Qt3.x on Linux and Qt2.3 on Windows). Benefits include updated widgets and removal of the non-commercial license exception in Windows.
  • Preformatted templates have been added for new TreeLine documents. User-created templates can also be added.
  • The content of right-hand views varies based on the selection and other options. A single selection still shows panes with the parent and its children, but a multiple selection will show all of the selected nodes in a single pane. Also, the Data Output view can optionally show an indented view of all descendants, and the Data Editor view splits the display into pages to speed up display.
  • More commands can make use of a multiple selection instead of just using the single active node. Also, an option can set the sequence of showing and exporting multiple selections to either tree order or selection order.
  • There is a tab on the left-hand view for a flat node list showing the selected nodes and all of their descendants. It is most useful for showing the results of filtering. There is a conditional filter for specific rules and a text filter that searches all fields for a string.
  • Several dialogs have been reworked for usability. The Configure Data Types and Print Options dialogs use tabs for better organization. The Configure dialog also has initially hidden advanced features and is now modeless, so it can be left open while applying configuration changes. The Sort, Export and Print Preview dialogs have also been updated.
  • Navigation through the tree is simplified by new commands that step through the selection history. Also, search strings are now highlighted in the Data Output view for text searches.
  • New dialogs have been added to customize keyboard shortcuts and tool bar buttons. There is also a directory for user-defined tree icons.
  • New file import and export options convert between an outline and an Open Document Format (ODF) text document, compatible with OpenOffice.org and KWord. Formatting is not maintained.
  • A Unique ID field type has been added that is automatically loaded with unique numbers. It is useful for link references.

  • New Features: A new command (View->Show Output Descendants) toggles the Data Output child view from showing only child nodes to showing an indented view of all descendant nodes. A button was added to the default toolbar for this command. Also, a new general option can make the descendant view the default at startup.
  • A new file export option converts an outline to an Open Document Format (ODF) text document, compatible with OpenOffice.org and KWord. The title of each node is assigned a heading style at the appropriate level. Any other text in the output of each node becomes normal text under the heading. Any HTML formatting is stripped.
  • ODF text documents can be imported. The node structure is based on the heading styles assigned in the document. Any text under each heading is assigned to that heading's node. Formatting is not maintained.
  • Updates: New commands were added to the Data Editor context menus that open the Configure Data Types dialog with the editor's type and/or field already selected.
  • Keyboard shortcuts were added for the commands that add HTML tags in the Data Editor. Icons were also added to these commands, so the toolbar editor can be used to place them on a toolbar if desired.
  • The interface for writing plugin modules was improved by adding interfaces to the keyboard shortcut editor and the toolbar editor. Also, a plugin interface to get the plugin's directory was added.
  • Any default text for new fields is added when a node's data type is changed (not just to a new node), as long as there isn't already data in a field with the same name.
  • Bug Fixes: Fixed a problem with the automatic opening of the last file used if there are no valid recent files.
  • Fixed a crash at file open if the file's owner is not found in a Linux machine's user password database.
  • Issues with the display of text have been fixed if the Qt library being used is version 4.2.3 or greater (the Windows build now uses 4.2.3). These issues showed up when scroll bars were shown and could hide the right edge of the text or the last line.
  • Multiple issues with dragging or pasting nodes between sessions of TreeLine were fixed.
  • If the Configure Data Types dialog is open, it is properly updated after the use of the undo command.
  • The find dialog is properly focused when repeatedly shown.

  • New Features: A Unique ID field type has been added. The field is automatically loaded with unique numbers. Initially, the field's format string is set to the desired first number in the series, with optional leading zeros and optional leading or trailing characters. All nodes of the data type will get an automatically assigned ID. The field format string will always show the next available number, which will be given to the next new node of that type.
  • The node sorting commands have been consolidated into a single new dialog. This provides more options for selecting what to sort (all nodes, branches, children or siblings) and how (by types and fields or by titles).
  • An option has been added to the numbering dialog to only number nodes where the number field already exists. This allows node types in the branch that do not have the number field to be skipped.
  • Updates: The tree view no longer scrolls horizontally when the selection is changed.
  • The focus behavior of the Data Editor view has been tweaked to allow easier tabbing between widgets.
  • Clicking on a selected node to rename it is now disabled when multiple nodes are selected. This avoids initiating a rename when the intent was to modify a multiple selection.

  • Fixed a freeze of the spell checker on some platforms.
  • An empty rectangle that was sometimes shown on the status line at the bottom of the main window has been removed.
  • An occasional problem with the import of generic XML was fixed.
  • The importing of files with bad Unicode characters has been improved.
  • The restoring of tree states when opening a file has been made more robust.
  • Fixed several other minor tracebacks that can show up in a terminal or log file.

  • When using the Find command with the Data Output view visible, the search string occurrences are highlighted in the output. Note: in Linux, this feature requires Qt v4.2 or greater and PyQt v4.1 or greater.
  • An icons directory has been added to the user configuration directory ("~/.treeline-1.1/icons" on Linux, "Documents and Settings\Application Dataellz reeline-1.1icons" on Windows). Image files (PNG or BMP) placed into this directory are available for use as tree icons.
  • "Move First" and "Move Last" commands have been added to the Edit menu. These commands move a child node to be the first or last child of its parent.
  • Updates: Horizontal scrolling of the tree view when the contents are wide is now supported.
  • The non-interactive command line options have been ported from the stable version. These options allow batch processing of file imports and exports.
  • Support for plugin extension modules has been ported from the stable version. The interfaces to TreeLine functions are unchanged, but existing plugins will need to be ported to the Qt4 library. An updated version of the httpLoad plugin is available.
  • A plugins directory has been added to the user configuration directory. This allows plugin installation without elevated privileges.
  • The code required to support GUI translations has been ported from the stable version, but the actual translations have not yet been updated.
  • Bug Fixes: The problem with cut/copy/paste operations in Windows that produced an error message at application exit was fixed.
  • Fixed several problems with the undo of changes to the Data Type Configuration.
  • A bug that could sometimes add an extra node during renaming in the Tree View has been fixed.
  • Problems encountered when typing a replacement word during spell check have been fixed.

  • One known bug in the Windows version produces an error message at application exit if cut/copy/paste operations were done during the session.
  • New Features: A new built-in editor for keyboard shortcuts has been added to the Tools menu. It has two tabs: one for menu commands and one for other commands. Simply press the desired key combination to change the shortcut in the selected entry. In general, printable characters without Ctrl or Alt modifiers should not be used for shortcuts. Although the editor will accept them, they may not work properly when certain widgets are focused.
  • A dialog to customize the tool bars has been added. It is accessed from the Tools menu. This allows the user to select small or large icons, define the number of tool bars, and define the commands included in each tool bar.
  • Updates: The saving of node open/close states for recently opened files has been ported from the stable version.
  • The restoring of splitter sizes and the active right-hand tab from the previous session has been ported from the stable version.

New in TreeLine 1.1.1 (Jan 17, 2010)

  • Notes: This is an unstable development snapshot. It is not feature complete and is sure to contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.0.0) should be used for any critical work.
  • Several features from the stable release are not yet implemented here. These include keyboard shortcuts for non-menu items, command line options, plugin support and translation support. Also, restoring of tree node open/close states, window split locations and active tabs are not yet available. And the documentation has not been updated.
  • On Linux, running TreeLine requires Qt version 4.1 or higher and PyQt version 4.0 or higher. Binary packages are not yet available for these libraries in some distributions.
  • One known bug in the Windows version produces an error message at application exit if cut/copy/paste operations were done during the session.
  • New Features: Printing functionality has been added to the development series. It now includes options to print the entire tree, the selected branches, or just the selected nodes.
  • A new Print Options dialog box is tabbed to give easier access to all of the options. There are buttons that give a more logical progression from the options to the print preview and to the print dialog.
  • Updates: The buttons at the bottom of the Configure Data Types dialog have been changed to OK/Apply/Reset/Cancel. This can reduce the number of mouse clicks.
  • The Configure Data Types dialog now defaults to the selected node's type when it is shown.
  • On Windows, the TreeLine.ini file has been moved from the installation directory to a location under the "Documents and Settings" folder. This avoids problems on multi-user systems and for users with limited access rights.
  • Bug Fixes: The Configure Data Types dialog now updates properly after copying types from another file, adding numbering, and rearranging by category and reference.
  • Various problems with node drag & drop that could result in inadvertent drops were fixed.
  • A bug that caused the right-hand view splitter to reset to even sizes was fixed.
  • Problems with saving changes to the format of file information fields were fixed.
  • Issues with some internal links and pictures in the help viewer were fixed.

New in TreeLine 1.1.0 (Jan 17, 2010)

  • Notes: This is an unstable development snapshot. It is not feature complete and is sure to contain bugs. Testing and bug reports are appreciated, but the stable release (TreeLine 1.0.0) should be used for any critical work.
  • Several features from the stable release are not yet implemented here. These include printing, keyboard shortcuts for non-menu items, command line options, plugin support and translation support. Also, restoring of tree node open/close states, window split locations and active tabs are not yet available. And the documentation has not been updated.
  • On Linux, running TreeLine requires Qt version 4.1 or higher and PyQt version 4.0 or higher. Binary packages are not yet available for these libraries in some distributions.
  • One known bug in the Windows version produces an error message at application exit if cut/copy/paste operations were done during the session.
  • New Features: TreeLine was ported to the Qt4 library. This involved a major rewrite of the code. The previous versions used Qt3.x on Linux and Qt2.3 on Windows. Benefits include updated widgets and removal of the non-commercial license exception in Windows.
  • The Configure Data Types dialog uses tabs for better organization. Many tabs contain advanced features that can be shown if desired. The dialog is also modeless, so it can be left open while applying configuration changes.
  • The content of the right-hand view varies based on the kinds of nodes selected. With a single parent node selected, it splits the view, showing the parent and its children (same as version 1.0.0). With a multiple selection or with a childless node selected, it shows all of the selected nodes in a single pane.
  • A general option sets the sequence for multiple selection to either tree order or selected order. When nodes are selected with control-click under the selected order option, they show in the right-hand view in the order they were picked. This sequence also applies to copy and export commands.
  • More commands make use of a multiple selection instead of just using the single active node. For example, the paste command will add duplicate children under each selected destination node.
  • The export command includes options to export the entire tree, the selected branches, or just the selected nodes.
  • In order to render the Data Editor right-hand view faster, there is a general option to set the number of "pages" initially shown. By default, only one page is shown. Buttons allow toggling to the next page or all pages.
  • There is a tab on the left-hand view to show a flat node list. It shows the initially selected nodes and all of their descendants. It is probably most useful when using filtering commands.
  • A conditional filter selects nodes based on rules for specific data types and fields, and a text filter selects based on finding the given text in any field. Both filters show their results in the tabbed "Flat View" and remain in effect until removed.
  • In the advanced mode, a child count field reference can be added to the output configuration. It shows the number of children at a specified descendant level.

New in TreeLine 1.0.0 (Jan 17, 2010)

  • Updates: A new version numbering system is being introduced. This release is 1.0.0, to better indicate its stability. The 1.1.x series will be started soon for less stable development releases.
  • The German translation of the ReadMe file has been updated.
  • Bug Fixes: Fixed a problem with duplicate nodes showing up when pasting multiple nodes on Windows.
  • Deriving types from other derived types is no longer allowed, since it did not function properly.
  • A problem with saving an encrypted file in the German version of TreeLine has been fixed.

New in TreeLine 0.14.1 (Jan 17, 2010)

  • Updates: Exported XSLT files now support field prefixes and suffixes. Thanks to Roland Meister for supplying patches.
  • Added functions to the plugin interface to allow plugins to open and close nodes.
  • Bug Fixes: Fixed a problem with displaying output from fields with non-ASCII characters in their names.
  • Auto save now works properly with encrypted files.
  • Notes: The French and German UI translation files and the French ReadMe files have been updated, but the German ReadMe files are not complete (but still usable). Updated files will be made available soon.

New in TreeLine 0.14.0 (Jan 17, 2010)

  • New Features: Data types can be set to derive their field settings from a generic type. This allows types with different output formatting to always use the same field data. Any changes to the generic's list of fields and field types are automatically reflected in the fields of all derived types. A derived option can be selected when copying a type, or a generic type can be specified from the derived type's "Advanced Configuration" dialog box.
  • Conditional expressions can be used to automatically assign a data type based on each node's content. Conditions are assigned to a generic type and its associated derived types. This allows the automatic assignment of different output formatting or different icons depending on each node's field data. Conditions are specified from each type's "Advanced Configuration" dialog box. Conditions do not have to be set for all types in a family, since, if no conditions are true for a node, the program will select a blank condition over a false one. In addition, conditions that are always "True" or "False" are available to toggle the output format of all nodes of a certain type simultaneously by modifying the condition.
  • By default, the spell check uses dictionaries for the current operating system language. A new option under "Tools->File Options" can be used to specify an alternate two-letter language code for the current TreeLine file. This only works with aspell and with the appropriate aspell dictionaries available.
  • A new menu item, "File->Open Sample", is a shortcut to the directory containing sample template files.
  • A new menu item, "Help->Help Contents", directly opens the "Using TreeLine" section of the ReadMe file.
  • Updates: When changing a node's type, if the result would have been a blank title, TreeLine now adjusts the new title fields to maintain the original title text.
  • Picture links with relative paths now resolve their reference based on the directory containing the current TreeLine file.
  • When applying a font tag in the editor view, the selection is maintained. This allows multiple tags to be applied.
  • HTML tags in field prefixes and suffixes are now removed in node titles.
  • Exported HTML has been made somewhat more compliant with standards.
  • A new option on the windows installer toggles the writing of installation directory and uninstall information to the registry. When this and other options are disabled, TreeLine can be installed without modifying the registry.
  • Four more sample files have been included. These files provide examples of using TreeLine's features and can be used as templates.
  • The ReadMe file has been updated with descriptions of the sample files, with more internal links, and with screenshots.
  • Bug Fixes: A problem with saving reference field settings for unused node types was fixed.
  • Formats copied from another file are now available immediately.
  • Node titles from HTML-enabled fields that contain escaped characters (, &) are now properly displayed.
  • Fixed some minor bugs concerning setting the default field value for new nodes.
  • A problem with exporting HTML directories with very recent versions of the PyQt library was fixed.
  • When displaying child data in node output, extra separators between blank entries are no longer shown.
  • Notes: The French and German UI translation files have been updated, but the French and German ReadMe files are not complete (but still usable). Updated files will be made available soon.

New in TreeLine 0.13.1 (Jan 17, 2010)

  • New Features: The number of recently used files listed in the File menu can be set using a new general option. Note that this also controls how many files have their tree states (open/closed nodes, etc.) saved.
  • Updates: TreeLine now sets the interface language using the LANG environment variable (if set) before falling back to other locale settings. This allows the operating system's locale settings to be overridden.
  • Bug Fixes: Problems starting TreeLine when the locale's LANG variable ends with "@euro" have been fixed.
  • Problems with the display of the rename edit box when creating new nodes in a long, scrolled tree view have been fixed.
  • Notes: The French translation files have been updated, but the German files are not complete (but still usable). Updated files will be made available soon.

New in TreeLine 0.13.0 (Jan 17, 2010)

  • New Features: The TreeLine user interface and documentation have been internationalized. Currently, translations are available for French and German. Volunteers to translate into additional languages are welcome.
  • Number formats can be internationalized. Periods and commas are supported as radix characters, and commas, periods or spaces can be set as thousands separators.
  • A new general option can set printing units to either inches or centimeters.
  • An external editor can be invoked from a Data Editor text field context menu. The EDITOR environment variable can be used to specify the editor to start, or, if the variable doesn't exist, TreeLine will prompt for an executable to set as the default.
  • Updates: The general option for a number editing format has been removed. Instead, the output format is displayed in the editor. Of course, any new entry with a reasonable format is correctly interpreted (but the correct radix character must be used).
  • Handling of spaces in filenames for the linking fields have been improved. Paths with spaces selected in the file browser are properly quoted (Windows) or escaped (Linux).
  • Page Up/Down commands in the Data Output view now leave a one-line overlap.
  • A Ctrl-C interrupt in a terminal is now ignored.
  • Bug Fixes: A dummy field has been added to imported bookmark separator formats to avoid configuration problems.
  • Paths in links to XSLT files are now properly handled when not in the same directory as the XML file.
  • Format text is now immediately updated when renaming fields.
  • Problems with undo after complex data changes have been fixed.
  • Errors due to having ASCII control characters in TreeLine text have been fixed.
  • Problems with spell check of unicode characters have been fixed.

New in TreeLine 0.12.0 (Jan 17, 2010)

  • New Features: A new AutoChoice field type provides pull-down selection of previously used entries. Any new entries are automatically added to the pull-down.
  • A new ExecuteLink field type runs an external program when its link is clicked. The command to run is given by the text of the field. Or the field's prefix may contain the program name, so that the field's text is used for arguments or file names. There is also a general option to disable these links when security is a concern.
  • A button that brings up a file browsing dialog has been added to the editor for Path, ExecuteLink and Picture field types.
  • Link fields can display alternate text in place of the target URL. This is done by specifying an alternate text field in the Advanced Field Format dialog.
  • Fields from child nodes can be embedded in their parent's output. Select a child reference from the Other Fields dialog. The child data is delimited with a separator string defined as a file option.
  • A new file option allows the removal of line breaks from each output line. This allows other HTML tags to be used to separate the output lines.
  • A "contains" rule to check for substrings has been added to the rules for node filtering and selective type changes.
  • The right-hand view that was previously used is now selected automatically on startup. This can be disabled using the general restore window geometry option.
  • Updates: Toolbar and tree icons are loaded from individual PNG files instead of from an XPM file. This improves icon quality.
  • Some features from the dialogs for data types and fields have been moved to advanced dialogs for simplicity.
  • Unicode characters are accepted for first-letter tree searches.
  • All calls to the eval() function have been replaced for improved security. Thanks to Roland Meister for providing patches.
  • The HTML version of the ReadMe file is now exported from the TreeLine version.
  • Spaces are permitted in Linux command line arguments.
  • Qt command line options are supported.
  • There have been several minor improvements to the plugin module interface.
  • Bug Fixes: A serious problem with deleting the last child under the root item has been fixed.
  • Some keyboard shortcuts for incremental searching have been fixed.
  • Open nodes are restored more consistently when opening files.
  • A font issue on early versions of Qt3 has been fixed.
  • The search for dtd files linked from XML files has been disabled to eliminate errors.
  • Visibility problems with long unbroken text lines in data editors have been fixed in Qt3.

New in TreeLine 0.11.1 (Jan 17, 2010)

  • Bug Fixes: Fixed a compatibility issue in the toolbar code that would prevent TreeLine from starting when PyQt was built against the newest versions of the sip library (versions 4.2rc1 and 4.2rc2).
  • Problems with editing the data of combination field types have been fixed.
  • A bug in the plugin interface for setting field formats has been fixed.

New in TreeLine 0.11.0 (Jan 17, 2010)

  • New Features: Icons have been added to the tree view. The icon assigned to each data type can be changed from the Configure Data Types dialog box. There are several generic icons available within TreeLine, and plugin modules can be written to add additional ones. A general option to disable the tree icons has also been added.
  • A command has been added to the data menu to copy type formatting from another TreeLine file. All types from the chosen file are copied. Any types in the current file with a matching name are overwritten, but types with unique names are retained.
  • Functions to import and export generic XML files have been added. These routines do not have much intelligence - each XML element becomes a node and each XML attribute becomes a field. This lets TreeLine function as a crude XML editor.
  • An editor height parameter has been added to text fields. This allows the number of lines in the data editor to be set for each field in each data type. As a result, the LongText field type becomes redundant and has been removed.
  • A field parameter has been added for fields that are required to be filled. Fields with this parameter set are marked with an asterisk in the data editor view.
  • Another field parameter has been added to allow certain fields to be hidden in the data editor view.
  • Updates: A fair amount of TreeLine code has been rewritten to improve efficiency and to ease future changes. Users should see improved speed with large files, especially noticeable when repainting during editing.
  • TreeLine now requires Python Version 2.3 or higher on Linux systems. The previous version of TreeLine will remain available for those stuck with older versions of Python.
  • HTML tags are now stripped from node titles in the left-hand tree view if the fields are set to output HTML rich text.
  • The plugin extension module interface has been expanded. Several added functions deal with node and field formatting. There is also a new callback trigger called whenever a node's data is modified.
  • A user plugin directory can now be specified in the configuration file. This allows plugins to be installed without root/administrator access.
  • An option has been added to the Linux installer to allow a different documentation directory to be specified.
  • Bug Fixes: Fixed a drag-and-drop bug that wouldn't allow nodes to be moved instead of copied in the Linux version.
  • Fixed the output of fields that include dashes and periods in their names.
  • A problem retaining the font setting for edit views has been fixed.
  • A rare startup failure due to problems with the encryption engine has been fixed.
  • A rare problem with foreign language encodings has been fixed.

New in TreeLine 0.10.2 (Jan 17, 2010)

  • Bug Fixes: Fixed a major bug that could prevent new nodes that contain date or time fields from being created.

New in TreeLine 0.10.1 (Jan 17, 2010)

  • Bug Fixes: Fixed a major bug that caused TreeLine to hang when attempting to open a recent file that no longer exists. This bug also caused startup failures if automatic opening was enabled with nonexistent files.
  • A bug in the plugin interface's getRootNode function was fixed.
  • Fixed a problem with file encryption on 64-bit systems.

New in TreeLine 0.10.0 (Jan 17, 2010)

  • New Features: One of the fields in a data type can be tagged as a reference field in the field-type dialog box. It defaults to the first field. This field is now used as the reference for the arrange and flatten by reference commands. It is also used by the new internal link feature, described below.
  • There is a new internal link field type. It creates a clickable link in the Data Output window that selects the next node with matching text in its reference field. If link or reference fields contain multiple lines, each line is treated as a separate link or reference, respectively. If desired, the same field can be used as both the link and reference fields, so that clicking on a keyword in one node's field selects the next node that also has that keyword. If exported to HTML, the internal links function as links to page anchors, but, in cases with duplicate references, they only find the uppermost reference on the page instead of the next one.
  • File encryption has been added as an option to password protect TreeLine files. Individual files can be set to encrypted mode from either "Tools->File Options" or from the save-as dialog. There is also a general option to set the default for new files. The encryption uses the SHA hash function as a stream cipher - it should be fairly secure.
  • A default initial field value can now be specified for a field type. Any new nodes get this value for the given data field when they are created. Also, in date and time fields, an initial value of "Now" can be used to get a time-stamp of node creation.
  • An interface to plugin extension modules has been added to TreeLine. This allows extensions to be written by various coders that provide functionality needed by a few users without adding bloat to the main application. Currently available plugins are listed on the "Downloads" page of the TreeLine web site. The plugins are installed by copying their Python file (*.py) to the plugins directory ("/lib/treeline/plugins/" on Linux or "TreeLinelibplugins" on Windows). A list of loaded plugins can be found using the "Help->About Plugins" command. Information about writing plugins can be found in the "plugininterface.py" file in the TreeLine source code.
  • Options have been added under "Tools->General Options" to set the fonts used for the tree view and for the right-pane editor views.
  • When printing, TreeLine will now avoid breaking pages between a parent and its first child. This behavior can be disabled by changing the "Keep first child with parent" print option.
  • Updates: Unicode text handling has been improved. Unicode can now be used in TreeLine file names, node data type names and field names. Also, imported and exported text files now use the proper encoding based on the system's locale settings.
  • A new sample TreeLine file with internal link fields has been added to the documentation.
  • Bug Fixes: An occasional problem bringing up the field-type dialog for file-info fields was fixed.
  • Avoid showing an oddly-named internal file-info data type in the dialogs after the file-info format is changed.
  • The option to restore the view state when opening recently used files now works more consistently.

New in TreeLine 0.9.1 (Jan 17, 2010)

  • Updates: Unicode text is now supported without requiring modifications of the Python sitecustomize file. The sitecustomize change has been eliminated from the installer.
  • The compressed ".trl.gz" extension has been added to the file open filter.
  • Information about the new TreeLine mailing list has been added to the documentation.
  • Bug Fixes: A bug that prevented XSLT file export under Linux has been fixed.
  • Special characters in bookmark URL's are now properly escaped during export to XBEL format.

New in TreeLine 0.9.0 (Jan 17, 2010)

  • New Features: Import and export of bookmarks in both the Mozilla HTML format (Mozilla, Firefox and Netscape browsers) and the XBEL format (Konqueror, Galeon and Elinks browsers) have been added.
  • An new option exports a portion of a tree to another TreeLine file.
  • Command line options have been added to allow non-interactive file importing and exporting. This allows automated runs to be scheduled. For more details, run "treeline -h" from the command line. If using a windows binary, output is supressed, so it must be directed to a log file ("treeline -h > log.txt").
  • Options have been added to work with compressed TreeLine files. Individual files can be set to compressed mode from either "Tools->File Options" or from the save-as dialog. There is also a general option to set the default for new files. Thanks to Mathieu Girard for contributing code.
  • A field reference to show data from any ancestor node has been added. The closest one with a matching field is used.
  • Fields containing file meta-data have been added. These include file name, path, size, and modified time.
  • Headers and footers for printing have been added. They can contain the file meta-data mentioned above. The headers and footers can also be shown in exported HTML files.
  • HTML character formatting tags can be automatically added to text using a new data editor context menu. Available tags include bold, italics, underline, size and color. Note that the fields must be set to display HTML content for this to be effective.
  • A new general option makes new fields default to HTML content. This allows for easier display of HTML formatting. This option is not enabled by default, since it does not preserve carriage returns and does not show non-escaped "" and "&" symbols.
  • When opening a recently used file, TreeLine will now restore the states of open and selected nodes. If desired, this feature can be disabled with a new general option. Thanks to Jan Hustak for contributing this code.
  • The toolbar has been split into two separate bars (general commands and node commands) that can be shown and moved independently. Again, thanks to Jan Hustak for contributing this code.
  • A new auto-save feature stores unsaved files with a "~" appended to the name. The backup files are automatically removed when the file is saved or TreeLine exits cleanly. The auto-save time interval is set in the general options.
  • New key bindings, set to Shift+Page-Up and Shift+Page-Down by default, scroll the current right-hand child view.
  • The XSL export command now prompts for the name of an optional style sheet (css). This name is stored in the TreeLine file as the default for future exports.
  • Updates: There have been some general improvements to the handling of imported and exported files.
  • File option settings can now be restored with undo/redo commands.
  • The README documentation files have been revised to be more organized and readable.
  • More sample files are provided. See the "sample_*.trl" files in the "doc" directory of the installation.
  • The Linux install script now includes an option for a temporary build root directory.
  • Bug Fixes: The up-arrow key binding did not work as expected in a deeply nested tree.
  • Some problems with auto-completion on data editor combo boxes have been fixed.
  • Problems in windows with some option spin boxes accepting new values have been fixed.
  • Fixed a compatibility issue with older versions of Python.

New in TreeLine 0.8.1 (Jan 17, 2010)

  • Bug Fixes: Fixed crashes that sometimes occurred when switching focus or views after renaming a new or existing node.
  • Fixed a compatibility issue with older versions of Qt (3.0.x).

  • Bug Fixes: Fixed crashes caused by right-clicking in the edit area or using the Alt-Tab key combination when renaming a node title.
  • Fixed problems occurring when several similar data type names were defined.
  • A rare problem with the installation script choking on image thumbnail directories was fixed.

New in TreeLine 0.7.3 (Jan 15, 2010)

  • New Features: Spell checking of the tree data has been implementedThis feature requires an external program, either aspell or ispell (see the System Requirements section).

  • Fixed some rare Linux install script problems with some systems.

New in TreeLine 0.7.1 (Jan 15, 2010)

  • Updates: The open file dialog now uses the directory of the most recently opened file as its initial directory.
  • To improve performance, some unnecessary refreshes of the right-hand view were eliminated.
  • Bug Fixes: Fixed problems with repeated uses of the search dialog command and the command to set the types of descendants.
  • Fixed problems with the data editor view in the mode that does not show children.

New in TreeLine 0.7.0 (Jan 15, 2010)

  • New Features: Added prefix and suffix tag formatting for groups of siblingsThese tags allow output to be formatted in tables or with bulletsSee the "sample_table.trl" file for an example of table formatting.
  • The size and position of the window and its splitters are now saved at exitA new option will disable this feature if desired.

  • The right views now update properly when the parent of the selected tree item is closed.
  • Problems involving copying with multiple nodes selected were fixed.
  • Problems with drag-and-drop on some Linux systems were fixed.

New in TreeLine 0.6.0 (Jan 15, 2010)

  • New Features: The three right views are now divided into upper sections for the selection's data and lower sections for the data from the selection's childrenView commands can be used to hide the display of children if desired.
  • Keyboard shortcuts can be customized by editing the TreeLine configuration file ("~/.treeline" on Linux, "treeline.ini" on windows)Any configuration files from previous versions should be deleted when installing TreeLine 0.6.0.
  • A new command will quickly set a node's data type.
  • Parent nodes will automatically open and close when found with the two search methods, by typing the first letter and with the "next sibling" keyboard commandThis behavior can be disabled with a new general option.
  • Typing a lowercase letter will move forward through the visible tree items that start with that letterAn uppercase letter will move backward.
  • Tree items (including those not visible) can be incrementally searched by typing "/" followed by the search string.
  • The Find dialog box is now modeless (the program may be operated while the dialog is open).
  • A "Choice" field type has been added that allows selection from a user-defined list of strings.
  • A "Combination" field type has been added that allows selection of several items from a user-defined list of strings.
  • Several linking field types have been added, including "URL", "Path", "Email", and "Picture"Clicking on a "URL" or "Path" in the output window will open the link in an external browserThe "Picture" fields are shown on in the output window for certain image formats.
