=head1 Notice
[ List each enhancement as a =head2 entry ]
+=head2 Now can dump compiled patterns before optimization
+
+This is primarily useful for tracking down bugs in the regular
+expression compiler. This dump happens on C<-DDEBUGGING> perls, if you
+specify C<-Drv> on the command line; or on any perl if the pattern is
+compiled within the scope of S<C<use re qw(Debug DUMP_PRE_OPTIMIZE)>> or
+S<C<use re qw(Debug COMPILE EXTRA)>>. (All but the 2nd case display
+other information as well.)

-close() on a pipe now preemptively clears the PerlIO object from the
-IO SV. This prevents a second attempt to close the already closed
-PerlIO object if a signal handler calls die() or exit() while close()
-is waiting for the child process to complete. [perl #122112]
+Perl no longer treats strings starting with "0x" or "0b" as hex or
+binary numbers respectively when converting a string to a number.
+This reverts a change in behaviour inadvertently introduced in perl
+5.30.0 intended to improve precision when converting a string to a
+floating point number. [perl #134230]
