=head1 Incompatible Changes
+=head2 Removal of the bytecode compiler and of perlcc
+
+C<perlcc>, the byteloader and the supporting modules (B::C, B::CC,
+B::Bytecode, etc.) are no longer distributed with the perl sources. Those
+experimental tools have never worked reliably, and, due to the lack of
+volunteers to keep them in line with the perl interpreter developments, it
+was decided to remove them instead of shipping a broken version of those.
+The last version of those modules can be found with perl 5.9.4.
+
+However the B compiler framework stays supported in the perl core, as with
+the more useful modules it has permitted (among others, B::Deparse and
+B::Concise).
+
+=head2 Removal of the JPL
+
+The JPL (Java-Perl Linguo) has been removed from the perl sources tarball.

Note, users experienced with PCRE will find that the Perl implementation
of this feature differs from the PCRE one in that it is possible to
backtrack into a recursed pattern, whereas in PCRE the recursion is

isn't supplied. Due to the optional nature of the argument, you can only
use it at the end of a prototype, or before a semicolon.
+This has a small incompatible consequence: the prototype() function has
+been adjusted to return C<_> for some built-ins in appropriate cases (for
+example, C<prototype('CORE::rmdir')>). (Rafael Garcia-Suarez)

+=head2 UCD 5.0.0

=head1 Installation and Configuration Improvements
+=head2 C++ compatibility
+
+Efforts have been made to make perl and the core XS modules compilable
+with various C++ compilers (although the situation is not perfect with
+some of the compilers on some of the platforms tested.)

+=head2 Ports

=head1 Selected Bug Fixes

=head1 New or Changed Diagnostics
=head1 Changed Internals
+The anonymous hash and array constructors now take 1 op in the optree
+instead of 3, now that pp_anonhash and pp_anonlist return a reference to
+an hash/array when the op is flagged with OPf_SPECIAL (Nicholas Clark).
