=head2 EBCDIC support
-Core Perl now mostly works on EBCDIC platforms. This is not true of
-many modules, including some which are shipped with this release. If
-you have resources to help continue this process, including test
-machines, send email to L<mailto:perl-mvs@perl.org>.

=head2 Literal control characters in variable names
-This deprecation affects things like C<$\cT>, where \cT is a literal
-control in the source code. Surprisingly, it appears that originally
-this was intended as the canonical way of accessing variables like
-C<$^T>, with the caret form only being added as an alternative.

-The literal control form is being deprecated for two main reasons: It
-has what are likely unfixable bugs, such as C<$\cI> not working as an
-alias for C<$^I>, and their usage not being portable to non-ASCII
-platforms: While C<$^T> will work everywhere, C<\cT> is whitespace in
-EBCDIC.

C<NULL> C<CvGV> to C<undef>. C<B::CV::GV> again returns a C<B::SPECIAL> object
in this case. [perl #119351]
-B version 1.44 (perl 5.19.2) introduced three new B::OP methods,
-C<slabbed>, C<savefree>, C<static> and C<folded>, but these have never
-actually worked until now. They used to croak.

The list of Perl versions covered has been updated.
-A function C<is_core()> has been added, which returns true if the
-specified module was bundled with Perl. Optionally you can specify
-a minimum version of the module, and the specific version of Perl
-you're interested in (defaults to C<$^V>, the running version of Perl).
