All known changes have been applied to all of the core, so you shouldn't have to worry too much. All tests pass nicely. Contrib maintainers: it's pretty straightforward for any given tool.

Because nearly every module is touched, this upgrade is not in a set of Subversion branches (way too much work). I am maintaining them on GitHub and keeping a branch synchronized with trunk:

So, I will put it to the TCC to think about the right time to apply these changes to trunk. I am deliberately sharing this now, after 2.9.1 has settled, since I think this is about the right time.
