New in RIOT 0.3.5 (Nov 28, 2009)
- bugfix: Save image fails in some cases. It occurs only when the image is opened by command line or drag & drop and "Show dialog on Save"
- is disabled (default) - the original image is not updated (overwritten).

- fixed handling of PSD files with a non zero file header reserved member
- fixed TIF module crashing on a malformed TIFF-JPEG compressed image

- Bugfix: Riotini is in the Riot folder with write permissions, but Riot

- DLL version: fixed black background for icons in some rare cases (no manifest in calling app)
- other minor improvements
New in RIOT 0.3.3 (May 13, 2009)
- plugins: fixed some memory leaks (especially noticeable in batch operations with RIOT_SaveToFile/RIOT_SaveToFile_U). Set file size function from IrfanView was affected by this problem.
- in the previous version of FreeImage bundled with RIOT v0.3.2 the support for different TIFF compression types was ommited. Now fixed.
- fixed some invalid pointer operations
- faster startup; ini file is read at once and stored/updated in memory
- speed optimizations for preview; fixed some bugs with automatic preview invoked more than once in some cases
- bugfix: rotating 4bit images now works
- cbanged the general font to an antialiased one (Trebuchet MS)
- minor corrections for display on 120 dpi font setting
- The ini file was not read at startup in some functions and that made the program ask for resample each time. Function affected from the plugin version were: RIOT_LoadFromFile/RIOT_LoadFromHBITMAP. In the standalone version opening images using the command line or dropping files onto the program icon in explorer.
- bugfix: File->Exit or pressing Esc terminates the application but does not save settings. Fixed !
- bugfix: after modifying Show Captions for main toolbar buttons the image is now centered.
- plugins: if file sent as parameter does not exist or left blank Original File Info is not updated (occurs in rare situations)
New in RIOT 0.3.2 (Apr 10, 2009)
- plugin: fixed a problem in 0.3.1 with the IrfanView plugin when retrieving configuration settings. An access violation error was thrown.
- configuration data is now stored in the current user's Application Data folder. If Riot.ini is found in the Riot folder, it is used only if the current user has write permissions for it. (this makes it compatible with putting Rot in Program Files for Vista)
New in RIOT 0.3.1 (Apr 10, 2009)
- bpp output now supported (automatically chosen when quantizating to less than 16 colors)
- keep transparency for 1 and 4 bit PNG
- added Save button for quick saving over the original. Save as is still there for choosing another folder
- plugins: RIOT_SaveToFile (function used by IrfanView "Set file size") can keep now metadata (exif, iptc, comments, etc). To operate in IrfanView it needs a new version of IrfanView (next after 4.23)
- upgraded libpng to 1.2.35
- some optimizations in FreeImage (from the official CVS)
- plugins only: fixed some object destruction bugs causing unexpected behaviour (usually access violations). This bug especially affects Compress to size.
- plugins: improvements in file info display from the title bar (don't display size twice when DIB size equals original image size from file).
- plugins: for unsupported images file info was not updated. In this situation it shows BMP as format
New in RIOT 0.3 Beta (Feb 19, 2009)
- The most important new features are:
- 1. New (improved) interface
- The user interface was modified with the help of users to be more attractive and practical.
- 2. Remember settings on exit
- Tired of enabling again your favourite settings ? Now the program stores last used settings on exit, including window state and size. Image format and maximum PNG compression state are not remembered because it may drastically slow things down.
- 3. New tabs for format settings
- The format settings are now separated in 3 tabs.The tabs are: format options, metadata and mask options. Each one appears only if neccessary (image contains metadata, image is transparent)
- 4. New transparency options
- Alpha was discarded when converting to 24 bits. All transparent pixels were set to opaque. This often lead to unexpected results when converting alpha transparent PNGs to JPEG or when using color quantization.
- Alpha compositing can be used now and a matte color can be chosen. The transparency can be kept or removed. When kept, a threshold is used for converting alpha transparency to indexed.
- 5. New function : in-place compare
- This very requested feature allows to alternatively display the original image over the optimized image to see small pixel changes as long as the corresponding button is pressed.
- 6. Plugin: import ancillary data from original filename
- When used as plugin the image is sent as DIB that is not containing any other informations than RGBA pixels. Unfortunatelly IrfanView does not use 32 bit data, only 24 - and the transparency is not sent. If a file exists, metadata, transparency and ICC profile from original file will be imported if the program is set to do it.
- 7. Auto-rotate images according to EXIF info
- Some modern digital cameras have a sensor that indicates the camera orientation. With this feature you can let the program use that information to automatically rotate images.
- 8. Check for updates automatically
- When set so, the program can check for RIOT updates on the internet.
New in RIOT 0.2.1 (Nov 27, 2008)
- added all corrections from 0.1.13 until 0.1.15 to fix bugs that affected 0.2
- JPEG processing speed improvement by 25%.
- This is done using SIMD optimized instructions (MMX, SSE,SSE2, 3DNow!).
- overall speed optimizations
New in RIOT 0.1.15 (Nov 21, 2008)
- plugins bugfix: fail to open an unsupported image type even if it was sent as DIB and the image exists
- The image type is displayed now in the original file info only if it is not BMP (avoid strange behaviour when image type not supported).
- bugfix: fit in window problems (again) fixed !
- minimum and maximum zoom constraints
- eliminated the nasty effect on image moving
- improved zoom accuracy
New in RIOT 0.2.0 (Nov 8, 2008)
- full unicode support
- added option to keep/remove embedded JPEG EXIF profile
- plugins: now fully compatible with ansi2unicode plugin from IrfanView
- plugins: new Unicode-enabled functions
