C<qr/\X/>, which matches a Unicode logical character, has been expanded to work
better with various Asian languages. It now is defined as an C<extended
grapheme cluster>. (See L<http://www.unicode.org/reports/tr29/>).

C<\X> will now always match at least one character, including an initial mark.
Marks generally come after a base character, but it is possible in Unicode to
have them in isolation, and C<\X> will now handle that case, for example at the

-XXX what does "files in the To directory" mean? -- dagolden, 2009-12-20
+The generated files in the C<lib/unicore/To> directory are now more
+clearly marked as being stable, directly usable by applications.
+New hash entries in them give the format of the normal entries,
+which allows for easier machine parsing. Perl can generate files
+in this directory for any property, though most are suppressed. An
+installation can choose to change which get written. Instructions
+are in L<perluniprops>.

- Export PL_curinterp symbol for MULTIPLICITY without USE_ITHREADS
-
- This is necessary for XS extensions that define PERL_CORE. In that
- situation PERL_GET_CONTEXT will resolve to PL_curinterp, which is
- normally not exported (extensions call Perl_Gcurinterp_ptr() to get a
- pointer to PL_curinterp instead). With USE_ITHREADS defined
- PERL_GET_CONTEXT will expand to Perl_get_context() even inside the
- core because the context needs to be fetched from threadlocal storage.

-commit 8a27a13e89107aaf68c0748b68ee71fbd86d774b
-
- [perl #71076] sort with active sub (5.10 regression)
-
- One of the tests in sort.t causes a bus error (or sometimes â\80\98Undefined
- subroutine calledâ\80\99) if run multiple times. This is because sort
- decreases the refcount of an active sub used as a comparison routine.
