+- Issue #1276: Add temporary aliases for CJK Mac encodings to resolve
+  a build problem on MacOS with CJK locales.  It adds four temporary
+  mappings to existing legacy codecs that are virtually compatible
+  with Mac encodings.  They will be replaced by codecs correctly
+  implemented in 3.1.
+
 - Issue #2834: update the regular expression library to match the unicode
   standards of py3k. In other words, mixing bytes and unicode strings
   (be it as pattern, search string or replacement string) raises a TypeError.
