|PERL5123DELTA(1)||Perl Programmers Reference Guide||PERL5123DELTA(1)|
If you are upgrading from an earlier release such as 5.12.1, first read perl5122delta, which describes differences between 5.12.1 and 5.12.2. The major changes made in 5.12.0 are described in perl5120delta.
There are no changes intentionally incompatible with 5.12.2. If any exist, they are bugs and reports are welcome.
Module::Build should be more reliably pass its tests under cygwin.
Lvalue subroutines are again able to return copy-on-write scalars. This had been broken since version 5.10.0.
For more details and discussion on the latter, see:

If you believe you have an unreported bug, please run the perlbug program included with your release. Be sure to trim your bug down to a tiny but sufficient test case. Your bug report, along with the output of "perl -V", will be sent off to firstname.lastname@example.org to be analysed by the Perl porting team.
If the bug you are reporting has security implications, which make it inappropriate to send to a publicly archived mailing list, then please send it to email@example.com. This points to a closed subscription unarchived mailing list, which includes all the core committers, who will be able to help assess the impact of issues, figure out a resolution, and help co-ordinate the release of patches to mitigate or fix the problem across all platforms on which Perl is supported. Please only use this address for security issues in the Perl core, not for modules independently distributed on CPAN.
