Downloads are available for Windows, various Linux distributions, and macOS. This release fixes the following three issues:

Bug fixes

• mkvmerge: all subtitle frames are now treated as key frames in order to fix
  wrong data in source files. Fixes #2541.
• mkvmerge: AV1: fixed frame timestamp calculation when reading bitstreams
  that lack timing information from IVF files. Fixes #2553.
• mkvmerge: Matroska reader: fixed an infinite loop that could happen with
  large video frames and applied timestamp files due to too much data being
  buffered at the wrong time. Fixes #2550.
