MKVToolNix v98 released

2026-04-05 — mosu

Hello there!

MKVToolNix v98 is now out, again just a pretty small release with just a handful of changes — but why hold off even longer? Who knows when things will pick up again. So here we are!

An important reminder for macOS users: I will stop providing macOS binaries and any kind of support for macOS in the second half of 2026 due to Apple discontinuing support for the Rosetta x86-to-ARM translation system. As my current build process only works on x86 (Intel) macs this will be the end of the line for any kind of mac support for me. There is some community support in the form of third-party builds over on the MKVToolNix forum.

You can download the source code or one of the packages. The Windows packages as well as the Linux AppImage are available already. The other Linux packages & the macOS disk image are still being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:
