I see beta 3 has “debug” in the name; whereas, beta 2 does not.
What does “debug” signify and which would be the more stable package, beta2 or beta3.debug ?
It looks like for beta 3 there’s both a debug and release (without -debug) build, while before it was just a release build. Debug builds are bigger and potentially a bit slower, but potentially offer more insight to the devs if something goes wrong.
Debug has embedded debug symbols which help generating useful bug reports. So if you are willing to contribute via testing pre-releases then you should download debug version otherwise non-debug version will be just fine.
Hardware support (does everything e.g. hardware acceleration, volume buttons, etc. work on Linux?)
Software support (evaluate every program you use daily/weekly/monthly and not just the software for photography).
How old is your PC (Linux Mint might work better on older machines)
I you try Linux just for digiKam I would not bother but if that is for rsync, rapid photo downloader, digiKam, etc. it might make sense.
Linux might feel a bit clunky compared to Windows but it offers better integration of such cool tools like exiftool, rsync, ffmpeg into your workflow via shell scripts.
