What's new in this version:

New features and enhancements:
- mkvmerge: MPEG transport stream reader: HEVC/H.265: added support for reading single-layer Dolby Vision from Annex B type bitstream read from MPEG transport streams. Partially implements #3113.
- mkvmerge: MPEG transport stream reader, HEVC/H.265 elementary stream reader: added support for reading dual-layer Dolby Vision with both the base & enhancement layers in the same track from Annex B type bitstreams in MPEG transport files & elementary stream files. Implements #3126.
- mkvmerge: MPEG transport stream reader: HEVC/H.265: implemented combining dual-layer Dolby Vision with base & enhancement layers in different tracks. Implements #3127.
- MKVToolNix GUI: multiplexer: added a new option in the preferences for always enabling 'forced' subtitle tracks. A subtitle track is considered to be 'forced' if: the corresponding property is set in the source file; the track's name contains the word 'forced' (in English); deriving the 'forced display' flag from file names is active & the file name matches the corresponding pattern. The option is disabled by default. Implements #3627.
- MKVToolNix GUI: multiplexer: the functionality for detecting file name sequences when adding files can now recognize the patterns used by GoPro's cameras for chaptered video files. Implements #3633.
- xyzvc_dump: the end position of the current NALU will be output in non-portable format as well.
- xyzvc_dump: HEVC: the tool will now also output the inner NALU type of Dolby Vision NALUs (`unspec62` and `unspec63`).

Fixed:
- mkvmerge: when the user requests processing be stopped after the video ends
- mkvmerge` will now take appending files into account properly. It won't stop processing unconditionally after the first file ends anymore. Fixes 3618.
- mkvmerge: AV1 handling in readers: the readers will now provide the pixel dimensions to the AV1 packetizer as early as possible, just like for other video packetizers. That way the pixel dimensions are available for calculating the display dimensions when command-line options such as aspect-ratio` & `--aspect-ratio-factor` are used. Before the change the calculation was done based on initial pixel dimension values of 0x0, resulting in display dimensions of 0x0, too. Fixes #3611.
- mkvmerge: HEVC/H.265 packetizer: when reading & appending HEVC/H.265 from Matroska, MP4/MOV or FLV files the first frame of all the appended files was sometimes dropped, resulting in broken video at the point where video is appended. Fixes #3479.
- mkvmerge: MPEG transport stream reader: when reading MPEG transport streams from Blu-rays the four-byte long `TP_extra_header` structure in front of the transport packets are now skipped properly. Before the fix a stray byte with value of `0x47` inside that `TP_extra_header` structure could have thrown off the detection of where the transport packets start, leading to mkvmerge dropping a few audio and/or video frames at the start of the file. Fixes 3632.
- mkvextract: AAC extractor: when an invalid program config element in the GA-specific config element is encountered, the program config element will be disregarded, which avoids mkvextract aborting with an exception. Fixes 3606.
- xyzvc_dump: fixed the tool aborting with an exception when the last NALU in an Annex B type file was shorter than four bytes.

Other changes:
- AVC & HEVC dumper development tool: the tool has been renamed from xvc_dump` to `xyzvc_dump` as `xvc` is an abbreviation for an existing video codec (Extreme Video Coding), and the tool has nothing to do with that codec.

What's new in this version:

New features and enhancements:
- MKVToolNix GUI: if the system's locale uses one of the Han scripts, the GUI will force Arabic numerals to be used in spin boxes. This prevents Suzhou numerals from being used which seems to be the default on Windows systems sold in China.

Fixed:
- build system: fixed detection of Qt6 if `clang` is used for compilation on Linux. In that case Qt's `qmake` added a `gcc`-specific option that `clang` doesn't understand, `-mno-direct-extern-access`. `configure` will now pass the parameter `-spec linux-clang` to `qmake` so that it uses the correct compiler flags.
- build system: fixed the use of `mktemp` to be more portable to e.g. macOS
- mkvmerge: if a video aspect ratio was given with `--aspect-ratio-factor`, the code would apply a second factor based on the pixel resolution, resulting in much too large values for the `DisplayWidth` element. For example, with a pixel resolution of 720x520 & an aspect ratio factor of 1/1 the result should be 720x520, but instead it was 900x520. Up until release 76.0 this has only happened when a track order was given (which unfortunately includes all invocations with MKVToolNix GUI as it always includes the track order). Starting with release 77.0 this has always happened due to the automatic sorting of tracks implicitly creating a track order, even if none was given.

What's new in this version:

New features and enhancements:
- Mkvmerge: AV1: added support for reading Dolby Vision from AV1 IVF & OBU streams
- Mkvmerge: MPEG TS reader: added support for colors in teletext subtitles
- MKVToolNix GUI: multiplexer: when adding files the GUI can automatically enable the "forced display" flag for subtitle tracks if the file name contains the word "forced" delimited by certain characters (configurable). This feature is turned on by default.
- MKVToolNix GUI: multiplexer: added the option `--stop-after-video-ends` to the dialog for additional command line options.
- MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the dialog allowing the user to select the playlist to add will now show audio & video track properties as well (pixel dimensions for video; sampling frequency, channels for audio).
- MKVToolNix GUI: header editor: in order to reduce confusion with users non that versed in Matroska elements, the naming of the two "language" track properties has been changed: the old element is now titled "Language (obsolete)" & the current, IETF BCP 47 based one is simply called "Language".
- MKVToolNix GUI: preferences: you can now use the "delete" key to remove entries from simple list widgets for strings (e.g. the list of recently used destination directories).

Fixed:
- Mkvmerge: DTS reader: if a DTS stream doesn't start with a DTS core but a sub-stream element (EXSS), the reader will now look for a core. If found, it'll start processing from there instead of from the start. This fixes the timestamp calculation if the sampling frequency in the core & in the extensions are different.
- MKVToolNix GUI: multiplexer: the "emphasis" and "stereoscopy" combo-boxes now have a much smaller minimum width, allowing to make the whole "properties" pane much smaller again.
- MKVToolNix GUI: macOS: when you install the application from the DMG it'll no longer register itself as an alternate handler for its supported file types. It seems like this overrode existing associations, forcing people to change them manually to whatever they wanted them to be. Additionally this forced the associated file to always be shown with an MKVToolNix icon. The GUI's own `.mtxcfg` files will still be registered. .

- A special mark has been added for a folder with marked files that are hidden by the applied mask.
- A complete overhaul of symbolic and other links processing has been made.
- An option to recover only marked files matching the applied file mask or all marked files has been added to the Recover dialog box.
- The algorithm that estimates chances for successful file recovery has been improved.
- Interface localizations have been improved.

Bug-fixes:
- R-Studio parsed only the GPT partition table, even when it was invalid, when both LDM/MBR and LDM/GPT were present on the disk. Fixed.
- The Recover marked command was inactive if marked files were invisible due to the applied file mask. Fixed.
- The Copy information command copied the information from the previous file when the information of the selected file didn't exist. Fixed.
- The Expand All command for the folder tree may have frozen on partitions with large numbers of folders. Fixed.
- The number of marked files may have been displayed incorrectly when the view was changed from Real, by Extension, by Time, etc. Fixed.
- Sometimes R-Studio may have crashed during file recovery. Fixed.
- Sometimes the built-in previewer may have frozen when showing damaged files. Fixed.
- Scan time and progress may have been displayed incorrectly while scanning several regions. Fixed.
- Disk scan may have crashed or frozen during the process and an attempt to stop it. Fixed.
- The Rescan the entire disk command may have failed for an already scanned disk. Fixed.
- The Scan dialog didn't size units when it was closed and then opened again. Fixed.
A lot of symlink processing bugs have been fixed, two being worst:
- If there was a symlink to another folder in a place to store recovered files, and there was a folder in the data for recovery which name coincided with that symlink's folder, the recovered data was written to the symlink's folder. That may have resulted in complete loss of files stored in the symlink's folder. Fixed. Now R-Studio saves recovered files only within the path(s) specified for storing recovered files.
- When files were marked and then umarked in a folder that was a symlink, the files in its target were unmarked, too. Fixed.
- Disс information wasn't renewed when the CD was ejected and the Refresh command was executed. Fixed.
- R-Studio tried to access an attached CD/DVD drive during device refresh which may have resulted in temporal freeze. Fixed. Now R-Studio accesses a CD/DVD drive only when it works with it. Fixed.
- Disk size wasn't shown for a CD/DVD disc under WIndows NT. Fixed.
- R-Studio may have temporally frozen while switching between the Real, Extension, XXX Time views for partitions with many folders. Fixed.
- Many internal bugfixes to improve program's efficiency.
- Hexadecimal editor may have frozen while opening a multi-volume image. Fixed.

What's new in this version:

New features and enhancements:
- Mkvmerge: AV1: added support for reading Dolby Vision from AV1 IVF & OBU streams
- Mkvmerge: MPEG TS reader: added support for colors in teletext subtitles
- MKVToolNix GUI: multiplexer: when adding files the GUI can automatically enable the "forced display" flag for subtitle tracks if the file name contains the word "forced" delimited by certain characters (configurable). This feature is turned on by default.
- MKVToolNix GUI: multiplexer: added the option `--stop-after-video-ends` to the dialog for additional command line options.
- MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the dialog allowing the user to select the playlist to add will now show audio & video track properties as well (pixel dimensions for video; sampling frequency, channels for audio).
- MKVToolNix GUI: header editor: in order to reduce confusion with users non that versed in Matroska elements, the naming of the two "language" track properties has been changed: the old element is now titled "Language (obsolete)" & the current, IETF BCP 47 based one is simply called "Language".
- MKVToolNix GUI: preferences: you can now use the "delete" key to remove entries from simple list widgets for strings (e.g. the list of recently used destination directories).

Fixed:
- Mkvmerge: DTS reader: if a DTS stream doesn't start with a DTS core but a sub-stream element (EXSS), the reader will now look for a core. If found, it'll start processing from there instead of from the start. This fixes the timestamp calculation if the sampling frequency in the core & in the extensions are different.
- MKVToolNix GUI: multiplexer: the "emphasis" and "stereoscopy" combo-boxes now have a much smaller minimum width, allowing to make the whole "properties" pane much smaller again.
- MKVToolNix GUI: macOS: when you install the application from the DMG it'll no longer register itself as an alternate handler for its supported file types. It seems like this overrode existing associations, forcing people to change them manually to whatever they wanted them to be. Additionally this forced the associated file to always be shown with an MKVToolNix icon. The GUI's own `.mtxcfg` files will still be registered. .
