1=encoding utf8 2 3=head1 NAME 4 5perl5123delta - what is new for perl v5.12.3 6 7=head1 DESCRIPTION 8 9This document describes differences between the 5.12.2 release and 10the 5.12.3 release. 11 12If you are upgrading from an earlier release such as 5.12.1, first read 13L<perl5122delta>, which describes differences between 5.12.1 and 145.12.2. The major changes made in 5.12.0 are described in L<perl5120delta>. 15 16=head1 Incompatible Changes 17 18 There are no changes intentionally incompatible with 5.12.2. If any 19 exist, they are bugs and reports are welcome. 20 21=head1 Core Enhancements 22 23=head2 C<keys>, C<values> work on arrays 24 25You can now use the C<keys>, C<values>, C<each> builtin functions on arrays 26(previously you could only use them on hashes). See L<perlfunc> for details. 27This is actually a change introduced in perl 5.12.0, but it was missed from 28that release's perldelta. 29 30=head1 Bug Fixes 31 32"no VERSION" will now correctly deparse with B::Deparse, as will certain 33constant expressions. 34 35Module::Build should be more reliably pass its tests under cygwin. 36 37Lvalue subroutines are again able to return copy-on-write scalars. This 38had been broken since version 5.10.0. 39 40=head1 Platform Specific Notes 41 42=over 4 43 44=item Solaris 45 46A separate DTrace is now build for miniperl, which means that perl can be 47compiled with -Dusedtrace on Solaris again. 48 49=item VMS 50 51A number of regressions on VMS have been fixed. In addition to minor cleanup 52of questionable expressions in F<vms.c>, file permissions should no longer be 53garbled by the PerlIO layer, and spurious record boundaries should no longer be 54introduced by the PerlIO layer during output. 55 56For more details and discussion on the latter, see: 57 58 http://www.nntp.perl.org/group/perl.vmsperl/2010/11/msg15419.html 59 60=item VOS 61 62A few very small changes were made to the build process on VOS to better 63support the platform. Longer-than-32-character filenames are now supported on 64OpenVOS, and build properly without IPv6 support. 65 66=back 67 68=head1 Acknowledgements 69 70Perl 5.12.3 represents approximately four months of development since 71Perl 5.12.2 and contains approximately 2500 lines of changes across 7254 files from 16 authors. 73 74Perl continues to flourish into its third decade thanks to a vibrant 75community of users and developers.

There may also be 88information at http://www.perl.org/ , the Perl Home Page. 89 90If you believe you have an unreported bug, please run the B<perlbug> 91program included with your release. Be sure to trim your bug down 92to a tiny but sufficient test case. Your bug report, along with the 93output of C<perl -V>, will be sent off to perlbug@perl.org to be 94analysed by the Perl porting team. 95 96If the bug you are reporting has security implications, which make it 97inappropriate to send to a publicly archived mailing list, then please send 98it to perl5-security-report@perl.org. This points to a closed subscription 99unarchived mailing list, which includes 100all the core committers, who will be able 101to help assess the impact of issues, figure out a resolution, and help 102co-ordinate the release of patches to mitigate or fix the problem across all 103platforms on which Perl is supported. Please only use this address for 104security issues in the Perl core, not for modules independently 105distributed on CPAN. 106 107=head1 SEE ALSO 108 109The F<Changes> file for an explanation of how to view exhaustive details 110on what changed. 111 112The F<INSTALL> file for how to build Perl. 113 114The F<README> file for general stuff. 115 116The F<Artistic> and F<Copying> files for copyright information. 117 118=cut 119
