• build system: Ruby 1.9.x is now required.
• all: enhancement: The architecture (32bit/64bit) is mentioned in the version information of all programs.
• build system: bug fix for 64bit builds on Windows (x86_64-w64-mingw32): use the correct processor architecture via separate Windows manifest files. Fixes mmg and mkvinfo not starting due to »error 0x0000007b«.
• mkvmerge: bug fix: Fixed a potential endless loop due to an integer overflow in the code removing AVC/h.264 filler NALUs.
• mkvmerge: bug fix: Fixed reading uncompressed PCM audio tracks from QuickTime/MP4 files in certain situations. Fixes #950.
• mmg: enhancement: Made the »scanned files« list box sortable by all columns. Fixes #954.
• mmg: enhancement: The »additional parts« dialog will now show the files that make up an MPLS playlist. This is for informational purposes only and doesn't allow changing the playlist itself.
• mkvmerge: bug fix: Reading from an MPLS playlist file is now done as if the second and following files referenced in that playlist had been appended to the first file from that playlist. Before they were treated as if they were additional parts. Fixes #934.
• mmg: enhancement: a couple of fixes to tooltips: 1. Content correction for »splitting by chapters«; 2. no ugly re-formatting with wxWidgets 3.0.0 on Windows.
• mkvmerge: bug fix: Improved the AAC, AC3 and MP3 header decoding error handling so that the corresponding parsing routines won't get stuck in endless loops when encountering certain garbage data patterns.
• mkvmerge: enhancement: unified codec names output by mkvmerge's identification mode for all file format readers.
• mkvinfo: bug fix: when setting the language with --ui-language a few strings were still translated using the system's default language.
• mkvextract: bug fix: if the track headers were located at the end of the file (e.g. after modification with mkvpropedit or mmg's header editor) then mkvextract was writing files with a length 0 bytes.
• mmg: bug fix: the »playlist items« list box in the »select playlist file to add« dialog was showing the items in reversed order. Fixes #952.
• mmg: bug fix: the »select playlist file to add« dialog can now be resized, minimized and maximized. It also remembers its position and size during runs. Fixes #951.
• mmg: enhancement: The user can select the default subtitle character set to use for newly added subtitle tracks in the preferences dialog as requested in bug #948.
• mmg: bug fix: fixed the tooltip for the subtitle character set drop-down box to match mkvmerge's actual behavior. Fixes #948.
• mkvmerge: new feature: implemented reading DTS audio tracks from MP4 files (with ESDS object type ID == 0xA9 (decimal 169) or FourCC == 'DTS ' or 'dtsc').
• mkvmerge: enhancement: allowed muxing Opus to WebM files.
• mkvmerge: bug fix: Fixed the mapping of the Opus element »seek pre-roll« and »pre-skip« to the Matroska elements »track seek pre-roll« and »codec delay«. Remuxing Matroska files without Opus created with earlier versions of MKVToolNix is enough to fix such a file.
• mkvmerge: bug fix: fixing the bitstream timing information of h.264/AVC writes clean values for 25000/1001 frames per second video (e.g. de-telecined PAL @ 29.97).
• mmg: bug fix: fixed a crash in during drag & drop operations in mmg's chapter editor.
