When it comes down to it, FPC 3.3.1 seems to be the first choice.
FPC 3.3.1 is the development version. All distributions including Linux distros and Lazarus release builds use the latest release version of FPC.
So, we desperately need a new release of FPC!
AFAIK FPC 3.2.3 branch is just fine. Certainly it is better then the 3+ years old FPC 3.2.2.
Please build a release out of it ASAP!
Yes, it would be time for a next major release, too, but let's not go there now.
