Changes 55.1:
The features for this release include support of CLDR 27 (with a major cleanup \ 
of region locales, among many other improvements), formatting for scientific \ 
notation ("1.2 × 10³"), an update to Unicode 7.0 data for \ 
spoof-checking, narrow AM/PM markers ("7:45p"), and various \ 
performance enhancements. For C/C++, there are new methods for flexible dates \ 
("Nov 10", or "Sept 2015"), named capture groups for regular \ 
expressions, formatting of compound units ("3.5 meters per second"), \ 
new C wrappers, and independent timezone resource loading. ICU4J has been \ 
improved and tested for using ICU4C data and for running on Android.
