Notice

Summary: please skip this release and wait for 3.3.3

Unfortunately,a subtle bug in the TASTy reader managed to survive the Release Candidate (RC) process. The bug caused 3.3.2 to emit TASTy files incompatible with previous releases in the LTS line, namely 3.3.1 and 3.3.0. This means that, should a library author release a new version using 3.3.2, all users still based on older 3.3.x releases will encounter issues. While a simple workaround exists - users can bump their patch version in the LTS line, which is safe and recommended - we regard compatibility in the LTS as paramount. Therefore, we have decided to abandon the 3.3.2 release completely. New testing measures will be introduced to avoid such situations in the future and to guarantee that LTS line remains internally consistent in all cases.
