What's new in this version:

Important notes:
- The string formatting library used was switched from `boost::format` to [`fmt`]. See the section "Build system changes" for details

New features and enhancements:
- MKVToolNix GUI: added an option in the preferences for disabling automatic scaling for high DPI displays
- MKVToolNix GUI: the GUI will now prevent the system from going to sleep while the job queue is running. This feature is implemented for macOS, Windows and Linux/Unix systems where the `org.freedesktop.login1.Manager` D-Bus interface is available

Bug fixes:
- Mkvmerge: chapter generation: the start timestamps of chapters generated in intervals was wrong for files whose smallest video timestamp was bigger than 0
- Mkvmerge: MP4 reader: fixed handling of atoms whose size exceeds the parent atom's size
- Mkvmerge, MKVToolNix GUI's chapter editor: the chapter name template will now also be used when reading Ogg-style chapter files with empty chapter names
- Mkvextract: AAC: mkvextract will now write the program config element (PCE) before the first AAC raw data packet if the PCE is present in the `AudioSpecificConfig` structure in the `Codec Private` Matroska element. The PCE carries vital information about the number of channels and is required in certain cases
- Mkvpropedit, MKVToolNix GUI's header editor: in situations when a one-byte space must be covered by a new EBML void element the following element must be moved up instead. If that moved element is a cluster, the corresponding cue entries will now be updated to reflect the cluster's new position
- MKVToolNix GUI: Windows: the application manifest is now included properly so that Windows actually recognizes it

Build system changes:
- Qt's D-Bus implementation is now required for building on systems other than macOS and Windows, The `boost::format` library is not used anymore
- The [`fmt` library]is now required. Versions 3 and newer are supported. As not all Linux distributions include packages for the library, its release 5.2.1 comes bundled with MKVToolNix. The `configure` script will check for a system version of the library and use it if present and recent enough. Otherwise it will fall back to the bundled version and link that statically
