-=item * "b . COND" in the debugger has been fixed
-
-Breaking on the current line with C<b . COND> was broken by previous work and
-has now been fixed.
-
-=item * Tying C<%^H>
-
-Tying C<%^H> no longer causes perl to crash or ignore
-the contents of C<%^H> when entering a compilation
-scope [perl #106282].
-
-=item * C<~> on vstrings
-
-The bitwise complement operator (and possibly other operators, too) when
-passed a vstring would leave vstring magic attached to the return value,
-even though the string had changed. This meant that
-C<< version->new(~v1.2.3) >> would create a version looking like "v1.2.3"
-even though the string passed to C<< version->new >> was actually
-"\376\375\374". This also caused L<B::Deparse> to deparse C<~v1.2.3>
-incorrectly, without the C<~> [perl #29070].
-
-=item * Vstrings blowing away magic
-
-Assigning a vstring to a magic (e.g., tied, C<$!>) variable and then
-assigning something else used to blow away all the magic. This meant that
-tied variables would come undone, C<$!> would stop getting updated on
-failed system calls, C<$|> would stop setting autoflush, and other
-mischief would take place. This has been fixed.
-
-=item * C<newHVhv> and tied hashes
-
-The C<newHVhv> XS function now works on tied hashes, instead of crashing or
-returning an empty hash.
-
-=item * Hashes will null elements
-
-It is possible from XS code to create hashes with elements that have no
-values. Perl itself sometimes creates such hashes, but they are rarely
-visible to Perl code. The hash element and slice operators used to crash
-when handling these in lvalue context. These have been fixed. They now
-produce a "Modification of non-creatable hash value attempted" error
-message.
-
-=item * No warning for C<open(foo::bar)>
-
-When one writes C<open foo || die>, which used to work in Perl 4, a
-"Precedence problem" warning is produced. This warning used erroneously to
-apply to fully-qualified bareword handle names as well. This has been
-corrected.
-
-=item * C<select> and package aliasing
-
-After package aliasing (C<*foo:: = *bar::>), C<select> with 0 or 1 argument
-would sometimes return a name that could not be used to refer to the
-filehandle, or sometimes it would return C<undef> even when a filehandle
-was selected. Now it returns a typeglob reference in such cases.
-
-=item * C<PerlIO::get_layers> and tied variables
-
-C<PerlIO::get_layers> no longer ignores FETCH on tied variables as it used
-to most of the time [perl #97956].
-
-=item * C<PerlIO::get_layers> and numbers
-
-C<PerlIO::get_layers> no longer ignores some arguments that it thinks are
-numeric, while treating others as filehandle names. It is now consistent
-for flat scalars (i.e., not references).
-
-=item * Lvalue subs and strict mode
-
-Lvalue sub calls that are not determined to be such at compile time
-(C<&$name> or &{"name"}) are no longer exempt from strict refs if they
-occur in the last statement of an lvalue subroutine [perl #102486].
-
-=item * Non-lvalue sub calls in potentially lvalue context
-
-Sub calls whose subs are not visible at compile time, if
-they occurred in the last statement of an lvalue subroutine,
-would reject non-lvalue subroutines and die with "Can't modify non-lvalue
-subroutine call" [perl #102486].
-
-Non-lvalue sub calls whose subs I<are> visible at compile time exhibited
-the opposite bug. If the call occurred in the last statement of an lvalue
-subroutine, there would be no error when the lvalue sub was called in
-lvalue context. Perl would blindly assign to the temporary value returned
-by the non-lvalue subroutine.
-
-=item * AUTOLOADing lvalue subs
-
-C<AUTOLOAD> routines used to take precedence over the actual sub being
-called (i.e., when autoloading wasn't needed), for sub calls in lvalue or
-potential lvalue context, if the subroutine was not visible at compile
-time.
-
-=item * C<caller> and tied C<@DB::args>
