Description

ICU is the premier library for software internationalization. This page contains the latest ICU 52 milestone 1 (52.0.1) build links.

Major changes since ICU 51 include the following:

Common Changes

  • Updated to Unicode 6.3 beta (but not UCA 6.3). In particular: New Bidi control codes, new Bidi_Class property values, and two new Bidi "bracket" properties. The updated Bidi algorithm implementation is not yet included. For other property value changes see the UAX #44 summary.
  • The first cut of CLDR 24 data is integrated, with significantly expanded data for many languages, but without conflict resolution so far, and there are some known issues.
  • Many bug & API doc fixes.

ICU4C Specific Changes

  • Improved implementation of thread synchronization, using safer and more efficient APIs on most platforms. It was necessary to deprecate and disable the runtime-customization of mutex functions. Build-time customization is still possible. (ticket #10051)

ICU4J Specific Changes

  • (TBD)

Known Issues

  • Plural implementaiton is incomplete
  • Exhaustive tests fail for timezones
  • C: ICU may fail to build under clang with #include <atomic>.  See #10271 for fix. 
  • C: In some environments (newer clang, older gcc/libstdc++) ICU may fail to build, see #10272 for workaround.
  • C: Some AlphabeticIndexTest failures when the tests are run in certain languages, see ticket #10277
  • C: Some VTimeZone exhaustive-test failures due to bugs in preliminary CLDR data, see ticket #10281
