+L<B> has been upgraded from version 1.44 to 1.45.
+
+Calling the C<GV> method on C<B::CV> objects created from a lexical
+sub would return nonsense, possibly crashing perl. C<GV> now returns
+C<undef> for lexical subs. [perl #118525]
+
+Added the C<NAME_HEK> method to return the name of a lexical sub.

-XXX Description of the change here
+The C<open> tutorial has been completely rewriten by Tom Christiansen, and now
+focuses on covering only the basics, rather than providing a comprehensive
+reference to all things openable. This rewrite came as the result of a
+vigorous discussion on perl5-porters kicked off by a set of improvements
+written by Alexander Hartmaier to the existing C<perlopentut>. A "more than
+you ever wanted to know about C<open>" document may follow in subsequent
+versions of perl.

+C<sv_pos_b2u_flags> has been added to the API. It is similar to
+C<sv_pos_b2u>, but supports long strings on 64-bit platforms.
=back
=item *
-XXX
+Autovivifying a subroutine stub via C<\&$glob> started causing crashes in
+Perl 5.18.0 if the $glob was merely a copy of a real glob, i.e., a scalar
+that had had a glob assigned to it. This has been fixed [perl #119051].
+
+=item *
+
+On 64-bit platforms C<pos> can now be set to a value higher than 2**31-1
+[perl #72766].
+
+=item *
+
+Perl used to leak an implementation detail when it came to referencing the
+return values of certain operators. C<for ($a+$b) { warn \$_; warn \$_ }>
+used to display two different memory addresses, because the C<\> operator
+was copying the variable. Under threaded builds, it would also happen for
+constants (C<for(1) { ... }>). This has been fixed [perl #21979, #78194,
+#89188, #109746, #114838, #115388].
+
+=item *
+
+The range operator C<..> was returning the same modifiable scalars with
+each call, unless it was the only thing in a C<foreach> loop header. This
+meant that changes to values within the list returned would be visible the
+next time the operator was executed [perl #3105].
+
+=item *
+
+Constant folding and subroutine inlining no longer cause operations that
+would normally return new modifiable scalars to return read-only values
+instead.
+
+=item *
+
+Closures of the form C<sub () { $some_variable }> are no longer inlined,
+causing changes to the variable to be ignored by callers of the subroutine
+[perl #79908].
+
+=item *
+
+Return values of certain operators such as C<ref> would sometimes be shared
+between recursive calls to the same subroutine, causing the inner call to
+modify the value returned by C<ref> in the outer call. This has been
+fixed.
+
+=item *
+
+C<__PACKAGE__> and constants returning a package name or hash key are now
+consistently read-only. In various previous Perl releases, they have
+become mutable under certain circumstances.
+
+=item *
+
+C</$qr/p> was broken in Perl 5.18.0; the C</p> flag was ignored. This has
+been fixed [perl #118213].
+
+=item *
+
+Starting in v5.18.0, a construct like C</[#](?{})/x> would have its C<#>
+incorrectly interpreted as a comment. The code block would be skipped,
+unparsed. This has been corrected.
+
+=item *
+
+Starting in Perl 5.001, a regular expression like C</[#$a]/x> or
+C</[#]$a/x> would have its C<#> incorrectly interpreted as a comment, so
+the variable would not interpolate. This has been corrected [perl #45667].
+
+=item *
+
+On non-threaded builds, setting C<${"_<filename"}> to a reference or
+typeglob no longer causes C<__FILE__> and some error messages to produce a
+corrupt string, and no longer prevents C<#line> directives in string evals
+from providing the source lines to the debugger. Threaded builds were
+unaffected.
+
+=item *
+
+Enabling "used once" warnings no longer causes crashes on stash
+circularities created at compile time (C<*Foo::Bar::Foo:: = *Foo::>).
