=head3 L<perlapi>
+The API functions C<perl_parse()>, C<perl_run()>, and C<perl_destruct()>
+are now documented comprehensively, where previously the only
+documentation was a reference to the L<perlembed> tutorial.
+
The documentation of C<newGIVENOP()> has been belatedly updated to
account for the removal of lexical C<$_>.
characters in the range C<\x00-\xFF> it matches, as well as a list of
the first few ranges of code points matched above that.
+=head3 L<perlembed>

+The examples in L<perlembed> have been made more portable in the way
+they exit, and the example that gets an exit code from the embedded Perl
+interpreter now gets it from the right place. The examples that pass
+a constructed argv to Perl now show the mandatory null C<argv[argc]>.

The description of the conditions under which C<DB::sub()> will be called
=item *
+C<exit(0)> in a C<UNITCHECK> or C<CHECK> block no longer permits the
+main program to run, and C<exit(0)> in a C<BEGIN> block no longer permits
+C<INIT> blocks to run before exiting. [perl #2754]

+=item *

The canonical truth value no longer has a spurious special meaning as
a callable. It used to be a magic placeholder for a missing C<import>
or C<unimport> method. It is now treated like any other string C<1>.
=item *
+Some convoluted kinds of regexp no longer cause an arithmetic overflow
+when compiled. [perl #131893]

The default typemap, by avoiding C<newGVgen>, now no longer leaks when
XSUBs return file handles (C<PerlIO *> or C<FILE *>). [perl #115814]
