Thanks!
I noticed that two of my performance patches were not included in the
release notes and I personally think one of them belongs in the release
notes while other not.
The one I think belongs is the one below since it it really results in
major speedups of lower(), upper(), initcap() and casefold() on ICU with
UTF-8. Not having to convert from UTF-8 to UTF-32 and back is often a
major speedup.

UTF8-optimized APIs.
