-keep in sync with the latest CPAN release.
+Carp::Heavy now ignores version mismatches with Carp if Carp is newer
+than 1.12, since Carp::Heavy's guts were merged into Carp at that

-The time taken to build perl on Windows has been reduced quite significantly
-(time savings in the region of 30-40% are typically seen) by reducing the
-number of, usually failing, I/O calls for each L<perlfunc/require> (for
-miniperl only).
-[L<perl #121119|https://rt.perl.org/Public/Bug/Display.html?id=121119>]

-About 15 minutes of idle sleeping was removed from running C<make test> due to
-a bug in which the timeout monitor used for tests could not be cancelled once
-the test completes, and the full timeout period elapsed before running the next
-test file.

-
-On a perl built without psuedo-fork (psuedo-fork builds were not affected by
-this bug), killing a process tree with L<perlfunc/kill> and a negative signal
-resulted in kill() inverting the returned value. For example, if kill() killed
-1 process tree PID then it returned 0 instead of 1, and if kill() was passed 2
-invalid PIDs then it returned 2 instead of 0. This has probably been the case
-since the process tree kill feature was implemented on Win32. It has now been
-corrected to follow the documented behaviour.

-
-When building a 64-bit perl, an uninitialized memory read in B<miniperl.exe>,
-used during the build process, could lead to a 4GB B<wperl.exe> being created.
-This has now been fixed. (Note that B<perl.exe> itself was unaffected, but
-obviously B<wperl.exe> would have been completely broken.)
-[L<perl #121471|https://rt.perl.org/Public/Bug/Display.html?id=121471>]
-
-Perl can now be built with B<gcc> version 4.8.1 from L<http://www.mingw.org>.
-This was previously broken due to an incorrect definition of C<DllMain()> in
-one of perl's source files. Earlier B<gcc> versions were also affected when
-using version 4 of the w32api package. Versions of B<gcc> available from
-L<http://mingw-w64.sourceforge.net/> were not affected.

-C<LC_NUMERIC> is now initialized to the C locale. This affects only
-C<XS> modules, as the Perl core usages always make sure this locale
-category is correctly set for their purposes. C<XS> code remains
-vulnerable to other code changing this category's locale. Further fixes
-are planned in v5.22 to reduce these long-standing vulnerabilities.

-Fixed a bug detected by valgrind where sv_pvn_force_flags() would
-check SvPVX() even when the SV hadn't been upgraded to a C<SVt_PV>.
-SvPVX() is only initialized when the SV is upgraded to a C<SVt_PV> or
-higher. [L<perl

-Fixed a bug in caller() introduced in 5.18.0. In some circumstances
-when caller() was called on an C<eval STRING> stack frame it would
-attempt to allocate the limit of the address space minus one, which
-would croak with an out of memory error, which would be caught by the
-eval. A change in 5.19.1 which increased allocation sizes to allow
-COW to operate more often rounded that allocation size up and wrapped
-to a zero allocation size, resulting in a crash when the source string
-was copied over. [L<perl
-#120998|https://rt.perl.org/Public/Bug/Display.html?id=120998>].
+index() and rindex() no longer crash when used on strings over 2GB in
+size.
