L<perl5360delta>, which describes differences between 5.35.0 and 5.36.0.

=head1 Incompatible Changes

There are no changes intentionally incompatible with 5.36.0.  If any exist,
they are bugs, and we request that you submit a report.  See

=head1 Configuration and Compilation

=over 4

=item *

C<Configure> probed for the return type of malloc() and free() by testing
whether declarations for those functions produced a function type mismatch with
the implementation.  On Solaris, with a C++ compiler, this check always failed,
since Solaris instead imports malloc() and free() from C<std::> with C<using>
for C++ builds.  Since the return types of malloc() and free() are well defined
by the C standard, skip probing for them.  C<Configure> command-line arguments
and hints can still override these type in the unlikely case that is needed.
[L<GH #20806|https://github.com/Perl/perl5/issues/20806>]

=head1 Testing

Tests were added and changed to reflect the other additions and changes in this
release.

=head1 Selected Bug Fixes

=over 4

=item *

An eval() as the last statement in a regex code block could trigger an
interpreter panic; e.g.

    /(?{ ...; eval {....}; })/

[L<GH #19680|https://github.com/Perl/perl5/issues/19680>]

=item *

An C<eval EXPR> referring to a lexical sub defined in grandparent scope no
longer produces an assertion failures.
[L<GH #19857|https://github.com/Perl/perl5/issues/19857>]

=item *

Writing to a magic variables associated with the selected output handle, C<$^>,
C<$~>, C<$=>, C<$-> and C<$%>, no longer crashes perl if the IO object has been
cleared from the selected output handle.
