Hey,

I’ve released v5.8.0. It adds a couple of new features and fixes a few bugs; most prominently mmg not displaying mkvmerge’s last couple of messages.

Here are the usual links: the home page, the source code and the Windows installer and 7zip archive.

All of the binaries that I provide myself are already available.

Here’s the full ChangeLog since release 5.7.0:

• 2012-09-02 Moritz Bunkus <moritz@bunkus.org>
  • Released v5.8.0.
  • Build system: dropped support for gcc 4.6.0.
  • mkvpropedit: new feature: Added support for adding, deleting and replacing attachments.
• 2012-09-01 Moritz Bunkus <moritz@bunkus.org>
  • mmg: new feature: chapter editor: Added support for the edition flags "hidden", "default" and "ordered" as well as the chapter values "segment UID" and "segment edition UID". Implements ticket #736.
• 2012-08-30 Moritz Bunkus <moritz@bunkus.org>
  • documentation: Added a Basque translation of mmg’s guide by Xabier Aramendi (see AUTHORS).
  • all: bug fix: Fixed a buffer overflow in the Base64 decoder routine.
• 2012-08-19 Moritz Bunkus <moritz@bunkus.org>
  • source: Various fixes for building with g++ 4.7.x and clang 3.1.
• 2012-08-08 Moritz Bunkus <moritz@bunkus.org>
  • Build system: Boost’s "bind" library is not required anymore. The C++11 features from "functional" are used instead.
• 2012-08-07 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: bug fix: MPEG transport streams whose timecodes wrap around/overflow are handled correctly. Fixes #777.
• 2012-08-06 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: bug fix: MP2/MP3 audio tracks in MPEG program streams that contained garbage at the start of the very first packet caused mkvmerge to use uninitialized/random values for certain parameters (sample rate, number of channels, and therefore also during timecode calculation).
• 2012-08-05 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: new feature: Added support for reading ALAC (Apple Lossless Audio Codec) from CAF (CoreAudio), MP4 and Matroska files. Implements #753.
• 2012-08-02 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: new feature: mkvmerge will remove stuffing bytes from MPEG-1/-2 video streams that are used to keep the bit rate above certain levels (the 0 bytes between slices and the following start code). Implements #734.
• 2012-08-01 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: bug fix: Fixed audio/video synchronisation when reading MPEG program streams with MPEG-1/2 video with respect to B frames. Fixes #579.
  • mkvmerge: enhancement: SRT files can have spaces in their timecode line’s arrow (e.g. "– >").
• 2012-07-31 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: bug fix: VC1: mkvmerge will now only mark frames as I frames if a sequence header precedes them directly. Fixes #755.
• 2012-07-30 Moritz Bunkus <moritz@bunkus.org>
  • all: new feature: Added a Basque translation by Xabier Aramendi (see AUTHORS).
• 2012-07-20 Moritz Bunkus <moritz@bunkus.org>
  • all: bug fix: The programs do not try to create directories with empty names anymore. This happened if the output file name for e.g. mkvmerge or mkvextract was only a file name without a directory component. With Boost v1.50.0 the call to "boost::filesystem::create_directory()" would result in an error if the name was empty (it didn’t in earlier versions of Boost).
• 2012-07-11 Moritz Bunkus <moritz@bunkus.org>
  • mmg: bug fix: Fixed mmg not reading the very last line of mkvmerge’s output. The result was that messages like "the cues are being written" did not show up in mmg and that the progress bar was not filled completely. Fixes #774.

Have fun.
