I know that most distributions and vendors take snapshots from the
release branch, but it would provide a good start and give somewhat
reasonable changesets compared to e.g. 4.1.2. E.g. you most likely don't
have to worry about most other parts of the toolchain.

E.g. GCC now adds explicit abort() calls for certain pointer casts. That
hit FreeBSD within OpenSSL pretty badly. The memory issues in the
compiler are supposed to be fixed.
