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.

     ICU: use UTF8-optimized case conversion API

     Initializes a UCaseMap object once for use across calls, and uses
     UTF8-optimized APIs.
