QGroundControl compatibility with mavlink

I am using a custom build of QGroundControl.
The latest release 4.2.1 is linked to an older version of Mavlink from November 2021
But the daily builds are over 4.2.0 from master branch are linked to newer mavlink of April.

I use Mavsdk 1.4 in companion computer, which relies on newer mavlink release.

Px4 12.3 is based on September mavlink version. And 13.0 is still beta

So, Will the daily builds be stable for usage? I am kind of confused with this versioning. Could someone please clarify the stable ones to use.
