Did you ever working on testing a lazarus or fpc release?

Very difficult. If a release is created from a branch, nobody can ensure
that all release builders built the release candidate from exactly the
same revision, if they don't, things might be broken when the final
release should be built.

At cvs times we did this for fpc and we had to lock the branch to
prevent commits (btw: can git lock branches ;)?), but nevertheless it
caused confusion. So we decided to built from tags and move the tag by
merging if really needed. Believe me, from 15 years fpc development,
we've a lot of experience how to built a release of something complex
like lazarus or fpc (fpc has even a defined release procedure, see
http://wiki.freepascal.org/Release_Template)
