##3.9.8 (07 October 2009)

• Added: added "/res:keep" CLI switch to keep the resolution by default. Note that CLI switches overwrite GUI defaults.
• Changed: reworked dialog for conversion options, added: store/reset defaults, stored defaults are automatically loaded in GUI mode
• Changed: appending "_exp" to the save file name is no longer done repeatedly but only once.

##v3.9.7 (07 September 2009)

• Changed: JAR contains (only the) sources which are released under the LGPL and Apache license.

##v3.8.2 (24 May 2009)

• Changed: VobSub: alpha of completely invisible captions is patched.
• Fixed: alpha/luminance comboboxes were disabled since 3.8.0 when switching to VobSub output mode and palette mode was "keep existing"
• Fixed: "move all captions" didn't work correctly for BDN/XML and VobSub imports (since 3.6.0) if a bitmap was cropped.

##v3.8.1 (22 May 2009)

• Added: introduced CLI option "/acrop" to set alpha value for cropping and patching color values to black.
• Changed: VobSub/BDN XML: transparent colors are assumed black to avoid scaling artifacts (same handling now for all formats).
• Changed: edit dialog's preview window better matches the target resolution for less scaling artefacts in preview.
• Changed: reworked limitation of selection window. Now based on unscaled coordinates to guarantee accuracy to single pixels.

##v3.8.0 (21 May 2009)

• Changed: VobSub: keeping existing palette is possible now if import and export format is VobSub.
• Changed: VobSub: the active language index ("langidx:") is now parsed and only captions fitting this index will be used.
• Fixed: VobSub: global offsets > 0 in IDX led to wrong image size (and wrong RLE decoding in some cases).
• Fixed: target bitmap and palette where not updated at the same time leading to GUI redraw issues.
• Fixed: erase patches were not updated correctly if free scaling was limited to screen size.

##v3.7.1 (19 May 2009)

• Fixed: BD-SUP palette fix (when converting from HD-DVD-SUP) introduced in 3.7.0 didn't work reliably.

##v3.7.0 (18 May 2009)

• Added: free scaling factors (x,y) to resize captions independently of resolution changes.
• Changed: all text fields react while typing and use background colors to give status feedback.
• Fixed: when converting from HD-DVD-SUP to BD-SUP it was not guaranteed that each last palette entry was transparent.

##3.6.0 (16 May 2009)

• Added: editing of "forced" flags (via edit dialog)

• Added: erasing of rectangular regions (via edit dialog)
• Changed: VobSub: bitmaps are automatically cropped on import

##v3.5.6 (15 May 2009)

• Changed: VobSub: parsing of packet is now always stopped when reaching offset of next caption even if control buffer is incomplete.

##v3.5.5 (12 May 2009)

• Changed: VobSub: added padding packets (and stuffing bytes via PTS length) to the exported stream.
• Changed: VobSub: invalid offset to end sequence only throws a warning, but import continues.
• Fixed: VobSub: entries in 4 color frame palette were truncated to two bits during import.
• Fixed: VobSub: padding by manipulating the PTS length was not always processed correctly during import.

##v3.5.4 (10 May 2009)

• Changed: VobSub: control header now can be split over two packets. Seems to increase compatibility with SubtitleCreator.
• Changed: some more info is printed in the non-verbatim output mode (loading/writing files)
• Fixed: BDN XML: due to the last fix in 3.5.3, 720p was not recognized any more

##v3.5.3 (07 May 2009)

• Changed: when converting multiple files from the command line, a fatal error will not quit the program but just skip the file.
• Fixed: BDN XML: 576i and 480i  are used for PAL and NTSC instead of 576p and 480p.

##v3.5.2 (06 May 2009)

• Changed: VobSub: wrong packet length is detected and fixed (-> now SUB/IDX files exported before 2.1 can be imported).
• Changed: VobSub: improved luminance threshold detection when importing SUB/IDX files.

##v3.5.1 (03 May 2009)

• Fixed: VobSub: delay was read from wrong position of control buffer (-> wrong end time).

##v3.5.0 (03 May 2009)

• Added: support for importing VobSub (SUB/IDX).
• Added: command line switch (/tmerge) for setting the maximum time for merging (BD-SUP) captions.
• Changed: forced flags are preserved when exporting to VobSub.
• Changed: added/changed comments in IDX files to workaround bug in VobsubMuxer.
• Changed: end time of one frame can be start time of the next frame (no forced gap of 1 frame any more).
• Fixed: assumed number of pixels in odd/even RLE buffers was wrong for captions with odd line numbers.
• Fixed: scaling of very small captions (like 3x3) could still lead to crashes when using filters with large radius

##v3.4.3 (26 April 2009)

• Fixed: when merging equal captions inside an epoch, the end time was not always updated correctly.

##v3.4.2 (24 April 2009)

• Fixed: crash when the very last epoch was discarded because of missing ODS/PDS.

##v3.4.1 (21 April 2009)

• Fixed: scaling images from/to 1 pixel width/height led to division by zero/out of memory in scalers (happened with empty PNGs after cropping). Now scaling from/to this small sizes is inhibited. Also bitmaps in the target are limited to a minimum of 2x2 pixels.
• Fixed: lower right coordinates displayed for target were wrong, also the window offsets were displayed for the source instead of image offsets.

##v3.4.0 (19 April 2009)

• Added: miscellaneous scaling filter modes (amongst others: Bicubic, Lanczos3 and Mitchell)
• Changed: improved quantizer to leave no multiple entries in the palette
• Changed: rewrote PNG importer to use palette of image if that is possible
• Fixed: added semaphore to synchronize GUI threads decoding captions (fixes crashes when quickly jumping through captions)

##v3.3.2 (18 April 2009)

• Fixed: exported PNGs had changed palette order (so palette entry 255 was not guaranteed to be transparent)

##v3.3.1 (18 April 2009)

• Fixed: using XML as input didn't work from command line if also a target was given.
• Fixed: output resolution given via command line did not influence selection in GUI.

##v3.3.0 (18 April 2009)

• Added: support for importing/exporting Sony BDN XML/PNG format (used by Sonic Scenarist). Images are automatically cropped on import.
• Added: new command line option "/fps:keep" uses source frame rate as target frame rate (for BD-SUP and XML)
• Fixed: a little inaccuracy in (all) the scaling algorithms led to slightly suboptimal results. The result of bilinear scaling is now very, very close to a reference implementation.
• Fixed: conversion dialog fps comboboxes showed "29.967" instead of "29.97" for NTSC frame rates.
• Fixed: crash when BD-SUP starts with invalid epoch.

##v3.2.0 (14 April 2009)

• Changed: palette is created by default when scaling, mode can be selected (keep palette, new palette, dither)
• Changed: reduced text output to a minimum. To get full output, select "verbatim" mode.
• Fixed: progress bar was never updated when importing HD-SUPs, also cancel didn't work
• Fixed: progress bar didn't work for very large files (during load)

##v3.1.0 (10 April 2009)

• Changed: depending on the resolution of an imported SUP, either BT.601 (PAL/NTSC) or BT.709 (HD) is selected.
• Changed: cropping is assumed to be symmetrical and now also affects screen size in exported IDX or SUP.
• Changed: reworked default VobSub colors a little to provide better anti-aliasing. Also white is used in combination with dark gray now.
• Changed: minimum distance between two equal captions is now fixed to 200ms and doesn't depend on minimum display time any more.
• Changed: merged code and look of preview windows.
• Changed: all (?) edit boxes select smallest/biggest valid value if given value is out of bounds instead of just ignoring invalid inputs.
• Fixed: Merging captions failed in certain cases, which also resulted in wrong end times
• Fixed: BT.709 color space assumes Cr/Cb values to be inside 0..240 instead of 0..235
• Fixed: exporting forced captions didn't work any more (introduced in 2.9)
• Fixed: value for min display time is also used if fix short frames checkbox is unchecked.
• Fixed: move dialog remembers screen ratio.

##v3.0 (08 April 2009)

• Added: cropping support (crop the first n lines)
• Changed: reworked BD-SUP parser again to support multiple objects per epoch and to split the epoch were it makes sense. Also equal captions can be merged now even if they're in separate epochs. The rework also fixes RLE decoding errors caused by wrong handling of multiple objects in 2.9.
• Changed: colorspace conversion according to BT.709 instead of BT.601. Doesn't seem to make much of a difference though.
• Fixed: the alpha fading detection for BD-SUPs could create wrong colors in certain cases.

##v2.9 (05 April 2009)

• Changed: DTS (and internal PTS) time stamps are calculated now based on decoding and composition pixel rates. Should hopefully improve muxing results of exported SUP streams.
• Changed: improved detection of start/end of caption - should result in less warnings and better handling of problematic SUPs
• Changed: better handling of BD-SUP palettes (multiple IDs, palette update, alpha blending detection)
• Changed: much more flexible handling of CLI parameters. Options are allowed now even if no target file name and/or no source file name is given.
• Changed: support for one asterisk in target file name even if there is no wildcard in the source file name. The asterisk will be replaced with source path+filename without the extension.
• Fixed: calling BDSup2Sub with source file name as only parameter would fail if the file name contained spaces. Now it should work with all file names as long as they don't have multiple SUP/SUB/IDX extensions in them.
• Fixed: when changing the caption number in the edit and move dialogs, the wrong caption number was displayed after returning to the the main view.

##v2.8 (02 April 2009)

• Added: drag'n'drop support
• Changed: if one parameter (which is neither "/?" nor "/help") is given, it's used as input file for the GUI
• Fixed: HD-DVD-SUPs: next DSCQ is checked to avoid endless loops.

##v2.7 (31 March 2009)

• Added: option to move all captions inside/outside bounds (typically the cinemascope bars)
• Changed: temporarily added workaround for (what I consider a) bug in SupRip's RLE decoder
• Changed: automatic language selection also from the CLI if no language is given explicitly

##v2.6 (27 March 2009)

• Added: menu entry to swap Cr/Cb components
• Changed: better detection for faded HD-DVD-SUPs
• Changed: improved luminance threshold detection
• Fixed: Cr and Cb color components were switched when writing BD-SUPs (introduced in 2.5)
• Fixed: DSCQ is updated instead of accumulated for HD-DVD-SUPs with multiple DSCQs

##v2.5 (26 March 2009)

• Changed: console is cleared before loading a SUP to avoid heap and performance problems (Swing text components are SLOW).
• Changed: when copying console output to clipboard, the clipboard is reset first to avoid OutOfMemoryException.
• Changed: improved console output for BD-SUP reading to use less lines in the console
• Fixed: Cr and Cb color components were switched when reading BD-SUPs (in since 1.0)
• Fixed: inconsistent behavior of "export forced" checkbox (probably introduced in 2.3)

##v2.4 (25 March 2009)

• Changed: Improved support for HD-DVD-SUPs (multiple DCSQ START commands are supported, DCSQ is accumulated)
• Changed: Fully transparent colors are always interpreted as transparent black to not mess with scaling
• Changed: Automatic language selection now only considers file name, not the path name
• Changed: Bilinear scaling is also used for scaling down
• Changed: Better exception handling for general exceptions inside threads
• Changed: Edit dialog: duration can be entered as float value now (just for consistency)
• Fixed: BD-SUP: subtitles without RLE buffer are ignored (led to NullpointerException)
• Fixed: Accidentally changed time format from "hh:mm:ss:ms" to "hh:mm:ss.ms" in IDX files.

##v2.3 (22 March 2009)

• Added: edit dialog to change offsets and timestamps
• Added: check/fix possibility for very short display durations. Also new command line option "/tmin".
• Added: Automatic selection of language for SUB/IDX export if filename contains (English) language name (e.g. "spanish")
• Changed: Split export dialog into conversion dialog and export dialog. Moved resolution setting to conversion dialog.
• Changed: Completely reworked the time stamp check. It's done at import now, not at export. Also the source time stamps are not altered any more to fix missing/invalid times.

##v2.2 (18 March 2009)

• Fixed: missing end times were not handled correctly.

##v2.1 (17 March 2009)

• Added: command line parameter "/dly" to define a delay
• Added: target frame rate auto detection for command line
• Changed: command line parameter "/fps" to allow setting of only the target frame rate
• Fixed: usage of wild card from the command line would cause exception when source file name didn't contain a path
• Fixed: wrong VobSub packet size if only the control header was shifted to the next packet, but the first packet was not completely filled.
• Fixed: delay can be entered in milliseconds again. It's adjusted to target frame rate automatically.

##v2.0 (15 March 2009)

• Added: New frame rate: 23.975Hz. Equal handling of frame rates for command line and export dialog (e.g. aliases)
• Added: Frame rate info is written into the PCS headers of created BD-SUPs (and read for src fps detection)
• Added: Wildcard support for command line (read online help for details)
• Changed: SUP: palette is only exported up to the highest entry actually used (previous versions always exported 256 entries)
• Changed: Increased resolution of all internal time stamps to 90kHz (was 1kHz)
• Changed: During export, start/end time (or start/delay) are synchronized to the target frame rate (special handling for PAL, NTSC and 24P)
• Fixed: HD-DVD SUPs were refused from the command line

##v1.9 (11 March 2009)

• Added: support for reading HD-DVD SUPs (I own only one HD-DVD, so chances are it won't work with many HD-DVDs)
• Changed: The same selectable values appear in the ComboBox for source and target FPS (still can be edited)
• Changed: Reworked online help a little bit (also added working Hyperlink to Doom9 thread and copy to clipboard functionality)
• Changed: Renamed Mode/Format ComboBoxes to "Output Format" and "Output Resolution"
• Fixed: wrong display of target image size (introduced in v1.6)

##v1.8 (13 March 2009)

• Added: introduced new resolution 1440x1080
• Fixed: bug in the palette conversion introduced in r1.6 that could lead to artefacts on the left side of the subpic (SUB/IDX export only)
• Fixed: wrong alpha threshold default in command line version (SUB/IDX export only)

##v1.7 (10 March 2009)

• Added: BDSup2Sub now also works from the command line. See online help for parameter description.
• Changed: Optimized RLE encoding for SUPs a little bit (two pixels of the same color don't use RLE code)
• Changed: Tried to add some better (?) fake time stamps to the ODS/WDS/PDS/END packets.

##v1.6 (08 March 2009)

• Added: support to write SUPs (kinda experimental though, SupRip doesn't like'em). This included a major rework of the program's structure, so I hope I didn't break anything.
• Changed: Rewrote upscaling function (bilinear: slower, but much better quality)
• Fixed: half of the languages in the language selection box were not displayed. While I was at it, I sorted the lower part of the list alphabetically

##v1.5 (06 March 2009)

• Added: possibility to edit/save/load Vobsub palettes
• Changed: Extended primary color detection to support "white,light gray" in addition to "dark gray, light gray"
• Changed: set default alpha threshold to 80
• Fixed: redraw bug and reduced memory needed for zoom modes.
• Fixed: bug that caused wrong start time in case of multiple start packets or missing end packets.
• Fixed: blatant bug in export of forced subtitles which would export the same frames over and over again

##v.14 (06 March 2009)

• Added: frame/sequence number checks/warnings
• Added: automatic elimination of double subtitle start frames.
• Changed: Tinkered around with progress dialog to solve problems under Vista. Can't test it though.

##v1.3 (04 March 2009)

• Added: ini file to store frame size/position and load/save paths. Probably more to follow.
• Added: upscaling (indeed the scaling algorithm already supported it, only the factors were wrong)
• Added: layout panel that shows the location of the subtitle
• Changed: x/y ofs from start PCS is used instead of that from the window definition (fixes most misaligned subtitles)
• Changed: Time stamp inconsistencies are reported and fixed
• Changed: Swapped checkboxes in export dialog to emphasize the relation between the "Change frame rate" checkbox and the src/trg FPS
• Changed: Allowed all output formats for the moment. Dunno where this will take us, but it's worth a try.
• Changed: Worked a bit on the user interface (less rescaling of components)
• Changed: Removed warnings about empty palettes since this seems to be pretty common.
• Fixed: All editable fields of export dialog read out again before saving (indeed already done in 1.2)

##v1.2 (02 March 2009)

• Added: workaround to prevent crash when loading SUPs in NTSC/PAL resolution.
• Added: fixed line feed after even and off RLE buffer since VobSub sometimes skipped the last line
• Changed: Reworked SUP multipacket parsing to support unlimited packets (kinda untested though for > 2 packets).
• Fixed: bug in detection of primary color & luminance thresholds.
• Fixed: Info was not updated when switching output format

##v1.1 (26 February 2009)

• Added: progress dialog for import
• Added: check for existing target files and write protection
• Added: detection of forced subtitles and the possibility to export only forced subs
• Added: Support for multi-packet pictures (well, exactly two packets are supported for the moment)
• Changed" removed some checks from RLE decoding to support some non-standard frames which write to the next line without EOL
• Fixed: two small bugs in run length decoding (fixes reading exports from SupRead)

##v1.0

• Initial release.
