Fvwm2 -> fvwm3

I installed Linux Mint 20 and then used fvwm2. Now I’d like to install Linux Mint 21. I know that the new version of fvwm is fvwm3. My question - if I will install fvwm3, the old config for fvwm2 still will work?

Yes, the old configuration should still work. There are some changes, some of the depreciated things (for 20+ years) have finally been removed and there are some new features, but for the most part it should work.

Thank you. But it turned out that there is no fvwm3 in the Mint’s repository, the fvwm2 only. I installed fvwm2.
