Contributions Manager:
The majority of the work for this release went into cleaning up and fixing the Contributions Manager. (What you see when importing Libraries, managing Modes, etc.) Please, please, please help us out and give it a lot of testing. This is old, messy, and important code that is easy to break in major ways. If you have trouble with it, please file an issue!
The “Manage Modes…” menu item was opening an empty window. #613
Fix Cannot invoke "javax.swing.JProgressBar.setVisible(boolean)" because "this.progressBar" is null error when using Update All. #618
Libraries from the Foundation (i.e. Video, Sound, and JavaFX) will now be reported properly on the stats page.
Updated the Wiki pages about Libraries, Modes, Tools, and Examples for Processing 4. These pages were copied over from the Processing 3 repository, but needed some cleaning. Still more work to do here, but it's a start.
Implemented per-line indicators for download/install status. Eventually these will replace the progress bar in the bottom panel.
Removed an old workaround for a NullPointerException while making selections. If it reappears, please file a new issue. #3667
@sampottinger saves us again:
“Cannot find a class or type named ‘PApplet’” error #626, #635
Cannot use @Override and @Deprecated in static mode #619, #622
color in imports shows up as an error in the editor (even though the code still runs) #521, #636
Sketch folders with spaces or hyphens showing errors in the editor window (even though the code still runs) #610, #637
Other Bug Fixes:
Help Menu sometimes disabled on macOS. This is a Java bug, but it's been closed as “cannot reproduce,” so I managed to find a workaround. #4353, #617, #638
Fixed ClassCastException with copy() and PGraphicsJava2D. #624
Additions? Why Not:
The shortcuts for Find Next and Find Previous (i.e. ctrl-G and ctrl-shift-G on Windows/Linux) now work inside the Find/Replace window.
Show a warning when calling clear() on the primary drawing surface. #627

New in Processing 4.1.1 (Nov 29, 2022)

This release adds initial support for Language Server Protocol, which means we will soon be able to integrate the compile/run process with other editors like Visual Studio Code. There is still a lot of work to be done here (this code is probably more “alpha” quality) but it's a good step forward. To use it, we'll first need an LSP “client,” which can be a community contribution so keep an eye out for that in the coming weeks and months. Thanks to @kgtkr for the LSP code here, it's a huge help. #117
Support has been added for extended language tags, which makes available a Traditional Chinese (zh_TW) translation in addition to the previously available Simplified Chinese translation (originally zh, now renamed to zh_CN). You can see the full list of supported language tags here. We will keep the existing two-digit tags in place for now, and update them as needed when new language translations are added. Read more on the Translations page on the Wiki. Thanks to @jsyeh for the zh_TW translation. #600
Since the redesign of Processing.org, the offline reference is too large to include the download. In this release, a “Download Offline Reference” item was added to the Help Menu, for people who need an offline copy. It creates a file called reference.zip in the sketchbook. If that file is present, then the Help menu links and Find in Reference will use that copy of the reference. If it is not present, online URLs will be used. You can also manually copy the reference.zip file from sketchbook to sketchbook. Put reference.zip in the root of your sketchbook and restart Processing so that it picks up the new file. For instance, in a class situation, you might put the file on a shared server and tell people where to find it. Read more on the Offline Reference page on the Wiki. #524, #213
Contributed fixes:
Size(863,863/2) inside setup() function (fix from @sampottinger) #602, #609
Pre-processor was inserting extra spaces (another from @sampottinger) #607, #609
Fix the JavaDoc for mousePressed variable from @SableRaf. #605
Other updates:
In some cases, the Theme was not being saved after Processing was restarted. #565
A few updates and clarifications in the size() reference.
The Java version has been bumped from 17.0.4 to 17.0.5.

New in Processing 4.0.2 (Nov 25, 2022)

the big ones:
OpenGL apps now work with macOS Ventura, once again thanks to @jaegonlee. #544
Library version number parsing wasn't ignoring comments properly, so libraries that followed the template closely were showing The version number for “…” is not a number. #586, #553
The Updates tab of the Contribution Manager was throwing error messages about this.progressBar. #567
fullScreen() with pixelDensity(2) was broken with the default renderer. On startup, the sketch would report Display -1 does not exist, returning 1 for displayDensity(-1). #487
JSSC update for M1/M2 from @sampottinger #525, #577
the li'l and medium ones:
After creating 26 sketches, the “take a break” message still showed up after restarting Processing. #582
With multiple users sharing a machine, Processing would not work properly for the second user due to a problem with the temporary directory. #549
Added explanation for how to fix Processing when a user disallows access to the Documents folder on macOS. #581
Fixed an infinite loop that could be caused by running out of options for a sketch naming scheme.
When calling random() on a list (now choice()) with no elements, it would throw a weird Exception. Now it throws a more descriptive exception.
need some help here:
Contributions from the community!
Loading SVG file was giving Illegal base64 character 20 encoding error. Fixed thanks to @jaegonlee and @vepo. #592, #599
Updated Catalan translation thanks to @trikaphundo. #550, #554
Updates to the Spanish translation, also from @trikaphundo! #552, #574
A couple fixes for the Ukranian language strings from @rzats. #585
@LesleyWagner fixed the vertical placement of top elements in the Manager window. #520, #539
Preprocessor fix from @sampottinger for function/variable "does not exist" errors reported when defining a class without setup() or draw(). #579, #597
steps forward:
Added a choice() method to the XxxxList classes, which returns a random value from the list. Similarly removeChoice() removes a random element from the list and returns the value.
Also added a choice() method that returns random integers. So int value = choice(10) is a shorthand way of saying int value = (int) random(10)
Removed the choice() (formerly random()) method from the XxxxList classes that took a PApplet object for its random number seed/generator. Just feels like overkill at this point.
internal changes:
Using more Java 17 syntax in the code. No plans to really scrub everything to change the syntax over, just a matter of cleaning things up as we go.
Fixed a potential casting problem with Platform and DefaultPlatform. Should have been unreachable, but fixed anyway.
Brought back getCodeIndex() for GUI Builder Tool… then removed it again. #545, #596
me talking on the wiki:
Added a Translations page to the 4.x wiki, which is update to the Localization page from the 3.x repository.
Posted an explanation of how to create a naming.json file so you can set up your own sketch naming schemes.

API changes and additions:
Added circle() and square() methods.
Added push() and pop() for parity with p5.js
Non-US keyboards have trouble with a couple of shortcuts, so their implementation has been moved to the language files.
Make JSONObject.quote() (both versions) public
Change behavior of the remove() method in IntDict, FloatDict, etc. It now returns the value removed, for consistency with the other remove functions (and most usefulness). In some cases, was returning the index, which isn't as useful. If remove() is called on a value that does not exist, an runtime exception will be thrown because there's no sensible way to indicate that nothing was removed. This is also more consistent with removeIndex() throwing and exception when the specified index is not available.
Contributed fixes:
Extended SVG support for fonts and text
Updated Russian translation, now can choose Russian in preferences
Turkish translation updates
Examples dialog was causing high CPU load
Show a warning when a font isn't what the user expected

Improve matrix performance in P2D/P3D
Initializing textures loads the pixels array, even if not needed aferwards
Improve startup time by skipping the Android SDK folder when listing sketches
PShape.attrib() and PShape.setAttrib() are not working
Still more bug fixes and improvements:
Improve startup time when user-specified fonts are not used. The default font will be faster, using ttf/otf is fine. Only load font list when createFont("The Font Name") is used, or PFont.list() is called.
"Sketch disappeared" infinite pop up dialogs
If settings() present but pixelDensity() is in setup(), no error message
Fix several out of date links in the Help menu

This has been a huge headache for us. We've repeatedly submitted the
software and asked Microsoft for help, but haven't had any luck.
If you run into this issue and would like to help, please submit the files
to Microsoft here: https://www.microsoft.com/en-us/wdsi/filesubmission
Perhaps if there are enough reports, they'll understand this is affecting
a lot of people.
New features:
It's now possible to make your own theme file for Processing. Copy the
theme.txt file from inside the Processing folder to your sketchbook
folder, and then edit away. For instance, to make a dark theme:
https://github.com/processing/processing/wiki/Dark-Theme-for-PDE
It's now possible to copy the text of the status bar. Click the clipboard
icon at the right-hand side to copy the text to the clipboard. To search
immediately, use shift-click.
The default search engine is Google, but you can modify that by altering
the 'search.format' line in preferences.txt
Added pyde as a supported extension, so double-clicking on Python sketches will launch the PDE.
Added Double and Long versions of the data classes. Not sure if we'll keep these, but we're trying them out.
Also add subset(long) and subset(double) to PApplet
Changed the internal Sort class to use int for comparisons for better accuracy, especially when working with double and long values.
Consistently implemented write(PrintWriter) in the List and Dict classes Added save(File) to the List and Dict classes
Prevent Table.sort() from throwing NullPointerException with empty cells
Updates:
Fixed up the Welcome dialog. When closing the window or hitting ESC,
the "show this" selection is recorded. Also clicking that text will
toggle the checkbox on/off, as users would expect.
https://github.com/processing/processing/issues/3911
https://github.com/processing/processing/issues/3912
Redesigned the Rename window to be less ugly. Now closes when ESC is pressed, and the default action is set so hitting Enter will work properly.
Rewrite exec() to do threads, also handle fast/excessive output cases
Rewrite requestImage() to fix errors/slowness/concurrency problems
Refactoring inside the completion code
Now using Java 8u181.

fixes:
Find in reference for size() opens StringList.size()
Limit rollovers on EditorStatus to the text portion. Clicking the status
area when a URL was showing was problematic because it's also the separator
used to adjust the relative size of the two panels.

New in Processing 3.0a11 Pre-Release (Jul 17, 2015)

new additions:
You'll be greeted by a Welcome screen. We haven't finished the text for one of these yet, so you'll see some lorem ipsum (fake) text instead. We'll wrap that up before the beta release.
breaking all of the things:
For Tool and Mode authors, you'll need to make some (small) changes.
These aren't structural, but will require a rebuild of your code. Our hope is that this will be the last round of changes for the 3.x series, and that it's now safe to update your Modes and Tools to be compatible with the final 3.x release.
Changes in this release:
Several classes have been moved to a new processing.app.ui package.
The processing.app package was much too unwieldy and made it difficult for people to hack on the PDE code.
Several functions have moved out of Base and into Util (or Toolkit).
Most of these are file-related (removeDir() and others), but the Base class had simply grown to a ridiculous size. It remains enormous but is a little less ridiculous.
Removed the init() method from PApplet; it's no longer needed
fixing all of the things:
Show warning when display spanning is turned off with fullScreen(SPAN)
Add note about headless exceptions that points to Github
Resize children[] so that getChildren() returns a correctly-sized array
clear() was broken (maybe related to #3317)
PGraphic ignores PNG transparency (regression from 3.0a5, same as #3378)
Move error messages out of PConstants
Remove launch(String) since it was calling itself, and anachronistic
Sketches with new fullScreen() method should grab focus by default

New in Processing 3.0a10 Pre-Release (Jun 10, 2015)

breaking things for the future:
Added fullScreen() method to make it far easier to run sketches using the full screen.
smooth() and noSmooth() can only be used once per sketch, in setup().
Re-opened the Gates of Hell by adding chaining operations to PVector
Changed exec() and open() to use varargs. Changed open() to launch() to prevent problems with Python Mode.
Replaced --full-screen command line option with --present to untangle full screen versus the "Present" command that places blanks the rest of the screen around a sketch.
ortho() function is being reworked to make it compliant
other changes and additions :
Added new application and export icons.
Add retina/high-res display support to OpenGL
Add pixelDensity(2) command to enable retina or high-dpi mode for your sketch. Make things look beautiful and crisp on expensive hardware!
Added displayDensity() methods to get the pixel density for individual displays. displayDensity() returns the density (1 or 2) of the default (or currently selected) display, displayDensity(1) returns the density of display 1. Guess how you get the density of display 2?
Add useful constructors to the Int/Float/StringList classes

New in Processing 3.0a9 Pre-Release (May 20, 2015)

New in Processing 3.0a8 Pre-Release (May 18, 2015)

Stabilizing the mess from 3.0a6 and 3.0a7.
If you're using Eclipse or another IDE, be sure to read the "changes" section below, for a change in how the size() command works.
fixes:
size() sometimes erratic (i.e default size used) This was often seen with large setup() functions, or on more esoteric platforms.
Command line "processing-java" was broken
Sketchbook window requires restart of Processing before updating after sketchbook location change.
Replace & Find was reading "Find & Replace"
"One file added to sketch" message when two files added
pop() was not implemented correctly in String/Int/FloatList
Errors in file name case differences not correctly reported
Single Frame (no screen display) PDF broken
"Buffers have not been created" error for sketches w/o draw()
changes:
Behind the scenes, the size() method is now moved out of setup() and into a method named settings(). The settings() is called before setup() and is the only place where size() can be used. If using Processing without the PDE (i.e. with another IDE like Eclipse), remove the size() method from setup() and instead place it like so - public void settings() { size(400, 400, P3D); // your size() command here }
The rest of your code remains unchanged. The PDE does this transparently, so 99% of people won't even notice this change. However, it allows us to fix (and avoid) a lot of really nasty complications that come from how Processing lets you switch between 2D drawing and OpenGL and even something like PDF with simple changes to the size() method.
We're trying "settings()" as the method name, but that may change in a future alpha release. Once we hit beta, it will not change.
For those familiar with them, the sketchWidth(), sketchHeight(), sketchRenderer(), etc methods should no longer be used. This new implementation of the settings() method is a simpler solution.
Added SVG Export library (works like PDF Export). This has not been tested heavily yet.
Replace Tweak Mode ColorSelector with JComponent version
Fairly major rewrite of createShape(), shouldn't affect anything, but keep an eye out for regressions.
Add new String/Int/FloatDict constructors that take an array for useful static/ initialization
Move svgz handling to PApplet, remove objz handling
Implement blendMode in FX2D
Added StringList(Object...) constructor to handle a grab bag of objects
Added appendUnique() to Int/Float/StringList to only add unique items to a list. Replaces the following code, making "set" operations easier - if (!theList.hasValue(value)) { thiList.append(value);}
Inside main(), don't set 'args' to a zero-length array if no args were passed in, instead leave 'args' null.
debugger :
Debugger "String is null" error when hitting breakpoint
Change "method" to "function" in a few error messages
Error message for incorrect function arguments is wonky

export to application:
The return of multi-platform export! Create applications for Windows and Linux while using OS X. Create a Linux application from Windows. Against my better judgement, we're supporting it again. It's extremely difficult, but was disappointing to remove it earlier.

New in Processing 2.1.2 (Apr 16, 2014)

New in Processing 2.1.1 (Feb 3, 2014)

New in Processing 2.1 (Oct 28, 2013)

Added an option to not embed the Java runtime into an exported application.
This saves you the 100 MB footprint, but requires your users to install Java 7u45 or later.
The new println() (see the beta 1 notes) makes some old code behave a little differently. In the past, println() with an array would write out the array, one element per line, with the index in the front. i.e.: PFont.list()) would write something like this to the console:
[0] "Serif"
[1] "SansSerif"
[2] "Monospaced"
[3] "Dialog"
[4] "DialogInput"
[5] "ACaslonPro-Bold"
[6] "ACaslonPro-BoldItalic"
Now it's going to write out something like: Serif SansSerif Monospaced Dialog DialogInput ACaslonPro-Bold...
To get the old behavior, use printArray(). It's the price of progress, and shouldn't really "break" anyone's code since it's just writing to the console. We think the new syntax outweighs the downside of the change.
With arrays of primitive types (int[], float[], anything that's not an object), we've added code so that println() works as before. But we can't do the same for arrays of objects, such as String.
The preference for font smoothing (anti-aliasing) in the editor has been reset in this release. Fonts are unusably gross on OS X (and Linux) without smoothing and Oracle's version of Java (now in use with 2.1), and many longtime users have anti-aliasing turned off. You can still turn off smoothing in the Preferences window, but the results may be poor.
bug fixes:
Fix dataPath() problem with OS X (was breaking Movie on export)
Command line processing-java was broken in 2.1 beta 1 on OS X
Fix a situation where processing-java would return 0 instead of 1 on errors
Alpha values from the pixels array were coming back as 0
Additional UI font tweaks due to decreased legibility with Oracle Java

Flicker issues when resizing P2D/P3D/OPENGL

New in Processing 2.1 Beta 1 (Oct 21, 2013)

major changes:
Java 7 is now used across all platforms. On Mac OS X, we're now embedding Java 7u45.
Major changes have been made to Export to Application.
Read here: http://wiki.processing.org/w/Export_Info_and_Tips print() and println() now make debugging fun! They can now take any number of parameters, which means that code like:
println(x, y, mouseX, mouseY); will print out 3 5 142 220
No more println(x + " " + y + " " + mouseX + " " + mouseY); that was for suckers!
A new serial library has been added! The results of Gottfried Haider's
Google Summer of Code project now replaces the old serial library.
And everyone should wish Casey Reas happy birthday today!
This release is my birthday present for him. What did you get him?
Here's a more detailed rundown of what else is in this release:
new features and additions:
For people using Eclipse, the new print() and println() methods add some quirks because of how println() works for arrays in previous versions of Processing. When printing an array, you should instead use the new printArray() function, which works the same as the old println().
This will help avoid the compiler warnings with Eclipse and others.
In the PDE, this should be transparent, because warnings are not shown.
Update the JavaDoc, remove java.* package prefix ugliness. Also link out to the online version of the Oracle documentation.
Major work on the source and the build scripts as we completed the transition to Java 7, and away from Apple's deprecated Java 6.
Incorporated a version of Oracle's appbundler for OS X build. Made heavy modifications to the original version to add features and simplify.
Culled un-needed resources from the Java 7 runtime to save space.
Unfortunately Java 7 is also much larger than Java 6, so the size change isn't as considerable as we would hope.
Remove unused/outdated 'Mangler' Tool example
Remove video library for other platforms in download. This saves significant space because we're not doing cross-platform export anymore.
Update apple.jar file with new version
Update build instructions on Github
Many changes to the Supported Platforms page
Updates to the Export page to cover changes in this release
Removed the 32- and 64-bit selector from the Preferences on OS X.
Java 7 on OS X only supports 64-bit, so 32-bit is no longer available.
editor fixes:
Deal with null/missing folders for Tools and Modes
Non-compliant libraries cause crash on "Add Library"
Bad tools could bring down the environment
Open new PDE maximized when current PDE is maximized
cmd-left was bringing up the text area popup, causing X Mode weirdness
core bug fixes:
This was an Apple bug, and is fixed by our switch to Oracle's Java 7.
Background color for present mode had no effect
Add desktopPath() and desktopFile() methods for testing (not finished)
Unicode NLF causing problems in XML files
Fix image transparency in PDF output
Java2D images crash after being resized
Constrain lerpColor() between 0 and 1. Unlike lerp(), where it might make mathematical sense, going outside the boundary colors produces really messy results.
JSONObject/Array.format(-1) not working on embedded JSONObjects
Fix insertRow() bug with Table
opengl updates:
Updated to JOGL 2.1.0
Fixed inconsistency with P2D and resetMatrix()
Deal with text rendering problems
Fix textSize() problem with P2D
Repair incorrectly applied transformations in retained mode
push/popStyle() was causing color problems with P2D/P3D
Child SVG elements were misplaced when rendering with P2D/P3D
SUBTRACT and DIFFERENCE blend modes are swapped
Throw an error for textureMode(REPEAT)
Vertex codes were not being properly set in P2D/P3D
Some box normals were inverted
new serial library:
Incorporate the new serial library. Woohoo!
64-bit version of serial library
Closed several serial bugs because they're no longer relevant:
font fixes and changes:
Add ability to change the editor (and console) font from a menu in the Preferences window.
Add ability to change the console font size from the Preferences window.
Allow editor and console font changes without restart.
Anti-aliasing fix for the editor line status.
Change to bold instead of semibold version of Source Code Pro.
The semibold wasn't mapping properly as the same family.
Use the same font in the console as the editor.
Fix Windows/Linux console font issues.
movie maker:
Fix default gamma issues inside MovieMaker by adding extra atom TGA files cause Movie Maker to not work properly
Fix file selection dialog with MovieMaker (instead of the nasty
Swing-based version that was in use)
Add support for many other image file types to Movie Maker

New in Processing 2.0.3 (Sep 6, 2013)

New in Processing 2.0.2 (Aug 15, 2013)

Bug fixes:
Fix Windows issues with associating .pde files
Present Mode does not work properly on Windows
pixels[] array not updated with Capture and P2D/P3D
Unable to get TAB key event with P2D/P3D renderer
Setting an INT4 uniform in PShader causes an out of bounds exception
Fix "less less" typo
Slash breaks syntax highlighting when spaces are involved Fix from Github user hamzaissa - thanks!
selectInput() in exported OS X sketch treats .app package as a folder
Code with a NUL character causes an error Also remove NUL characters when loading PDE files
Allow delete of files in unsaved sketches
UnsatisfiedLinkError was causing huge/unreadable message
selectInput() in exported OS X sketch treats .app package as a folder
Retain blendMode() between frames
Contribution managers:
Support multiple categories for libraries
Notify users that Modes and Tools require restart.
Change the location of the manager download to something more stable.
Restrict library categories to the ones in the document. If it's not correct, shows up as 'other'.
Catch Errors (not just Exceptions) when loading libraries, modes, and tools. Handles UnsupportedClassVersionError and other quirks.
Redo handling of "old" versions of contributions.
Update example list when library is installed
Data, data, data:
Error in IntList and FloatList insert()
Add a sort() method to Table.
Implement version of Table that takes a dictionary file. Syntax is: Table t = loadTable("bigdata.tsv", "dictionary=bigdata-dict.tsv") This allows you to set the data type of columns before loading, which provides much better performance and lower memory usage.
Constructing table from an Iterator is missing
Add sum() to IntList and FloatList
When using increment() on IntList, make sure the index exists and automatically resize the list if necessary. This is more in keeping with increment() in the Dict classes.
getSubset() broken in IntList, StringList, and missing from FloatList
Add join() method to Int/Float/StringList
Add getContent(defaultValue) to XML
Add isNull() (returns boolean) to JSONObject/Array
Add getXxxx(xxx, defaultValue) methods to JSONObject/Array
Internal changes you'll never notice... unless I broke something:
Add an exception wrapper for startup, hopefully we can catch/debug more "Processing can't start!" issues with this.
Update JNA from 3.2.4 to 3.5.2.
Updated JOGL to 2.0.2.
Added methods to move files to Trash/Recycle Bin where available.
Implement basic proxy server support for update checking and the contribution managers.
Basic getShape(ch) implementation for font glyph shapes. Not finished and (therefore) not yet documented.
Change QUAD_BEZIER_VERTEX to QUADRATIC_VERTEX to match the API call (because this lives inside PConstants).
Add retina switch for PApplet to set useActive with OS X and 7u40. Prevents speed/performance issues with old sketches on retina macs.
Add error message for raspberry pi (and others?) about int buffers
Changes:
Experimental Mode has been removed from the default download, so that it can be updated more frequently. Install it and help us test what will become the 3.0 release of Processing!
Add "Processing Foundation" to the Help menu.

New in Processing 2.0.1 (Aug 15, 2013)

New in Processing 2.0 (Aug 15, 2013)

New in Processing 2.0 Beta 7 (Dec 8, 2012)

[ changes ]
Removed all imports that aren't covered in the Processing reference. If you use java.awt, java.util, or other classes in your sketch, you will need to add an import line to the beginning of your sketch.
Only the classes that are covered in the reference (HashMap, ArrayList, and some others) are now imported by default. This has been done to improve
overall cross-platform parity and to avoid users unknowingly adding Java classes, and then the sadness that comes when switching to Android or JavaScript modes.
The list of imports is now hard-coded (no longer read from preferences.txt)
and includes the following:
import java.util.HashMap;
import java.util.ArrayList;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;
If we're missing anything that's not covered in the reference, please let us know via the bugs database.
A new "experimental" mode has been added. It's the start of combining two
of our Google Summer of Code projects (DebugMode and XQMode) to enable a debugger and on-the-fly error checking. We're including it in the release so that folks can test it out and let us know how it's doing. The interface still needs work and its innards may be a bit buggy, but it represents some exciting upcoming improvements for the PDE.
hint(ENABLE_ACCURATE_2D) has been renamed to int(DISABLE_OPTIMIZED_STROKE) to better reflect what it actually does. Reference has been added.
OpenGL drawing is significantly faster when the fill and stroke of a shape is drawn separately. This leads to visual artifacts on shapes where both fill and stroke is enabled (not a great idea in 3D anyway), so this option fixes the visual artifacts at the expense of speed.
Sketch names can no longer begin with underscores (fixes an Android compatibility issue). This was changed in recent releases, but missing here.
Set quality level higher when exporting JPEG images. This will result in larger JPEG files with save() and saveFrame(), but the default quality setting in the past was unacceptable for many/most projects. See the bug report link for how to implement in case you want to set the quality lower (or even higher) than the new default.
Table row iterating syntax has changed. This code:
for (TableRow row : table) { ... }
has now changed to
for (TableRow row : table.getRows()) { ... }
(This may change to rows() on the next round, pending other API tweaks)
Change default for shift-backspace to just be backspace. To change it back, set editor.keys.shift_backspace_is_delete=true in preferences.txt.
Implement clip() and noClip() to set the clipping region.
Added blendMode() feature.
Add different styles of arc drawing.
Added XML.getLong() (also updated Android)
Implement back-buffer sampler in OpenGL renderers.
Change how get(x, y, w, h) was handled with offscreen areas.
Make key and mouse events interleave, also improve threading.
Changed event constants to PRESS, RELEASE, CLICK, DRAG, MOVE, ENTER, EXIT instead of past-tense versions of the same.
Removed mask(int[]) from PImage.
Implement postEvent() to put new events on the queue.
Add mouseEntered/Exited on the desktop.
Change output from processing-java to be UTF-8 encoded.
Remove requirement for Google APIs in Android mode.
[ bug fixes ]
mouseButton not being set properly in mouseClicked.
mouseButton is 0 in mouseReleased() on OS X
mousePressed() coloring now different from mousePressed
Still not necessarily perfect, but it's a big improvement.
Note for people implementing their own Modes: FUNCTION1 and FUNCTION2 have now been added for functions with parens.
Prevent errors on first line of a new tab from highlighting the last line of the previous tab. In particular, a single letter on a new tab was highlighting the last line of the tab to its left.
Android debug information wasn't being passed through to the console. In addition, on Windows, error reporting wasn't working properly (couldn't find the right line or report the error correctly).
Fix ugly results from resize() command on PImage:
P2D/P3D PGraphics buffer failing to draw if larger than main surface.
Fix double error report when textMode(SCREEN) was used:
textMode(SCREEN) has been removed from Processing 2.0.
textMode(256) is not supported by this renderer.
image(pgraphics, x, y, w, h) was only drawing once when shrinking.
beginShape(QUAD) was not working with Java2D.
Relative coordinates not updated properly on closepath with SVG files.
PShape and lights results in more lit vertices.
Implement anisotropic filtering when using OPENGL.
Update reference for begin/endContour.
Fix "expecting EOF, found 'import'" error on previously working sketch.
Prevent potential race condition when resizing sketches.
Mode detection wasn't properly ignoring code inside comments.
Fix error line numbers from command line version to count from one instead of zero, so that they're compatible with other systems.
Sketches exported to Linux weren't passed the command line arguments
"electricScroll" feature was causing weird jumps when double-clicking
Crash during library download was causing empty library list
In the net library, clientEvent() called even w/o data from server
Add Server.ip() method to get the IP address of the host machine.
Modify â€œCopy as HTMLâ€ to add second HTML data type when writing the clipboard
Fix contributed by Ostap Andrusiv--thanks!
Shaders are passed wrong defaults when calling "filter" on a PGraphics object
beginContour() behaves differently in immediate and retained modes
P2D/P3D crashes when trying to display unicode text
Fix for PMatrix3D.mult() when vectors are identical
Curves weren't rendered seperately when P3D or P2D specified.
FBO handling in PGL is not transparent.
Use of pixels[] array breaks after resize in OpenGL.
No stroke with OpenGL sketches on a 2007 Mac Mini (GMA 950)
ortho() displays strange line widths.
Resizeable frame crashes sketch with AMD video card.
begin/endShape with a single vertex causing crash on P2D/P3D.
Using a PGraphics as a texture produces visual artifacts.
[ fixed earlier / cleaning ]
When turning smoothing on, internal lines of shapes are visible.
textAlign(CENTER) with P3D and OPENGL produces messy result
Signature issue on contributed libraries affects unrelated OpenGL sketches
Implement efficient version of copy() in PGraphicsOpenGL.
copy() does not update the screen with OpenGL.
strokeCap() and strokeJoin() for use with OPENGL.
Fix inconsistent anti-aliasing with OpenGL.
noCursor() + OPENGL = won't get past setup()
set() requires updatePixels() with OpenGL.
Share interface for 3D across desktop and Android.
Distortion of 2D shapes when sphereDetail() is used.
OPENGL renderer stops rendering after text is written using textMode(SCREEN)
Support 'black' as color for SVG files (fix from PhiLho)
Catch sun.dc.pr.PRException?
Image created with img.get() works incorrectly when using filter()
copy(image with transparency) doesn't keep the transparency at start up.
Defects in the tessellation of SVG shapes in A3D
Blacked-out screen when restoring Android app from background.
Excessive rotation of application causes memory to run out
Should alpha PImage stuff use a non-4byte config?
Rounded rect support on Android
