=head1 NAME
-[ this is a template for a new perldelta file. Any text flagged as
-XXX needs to be processed before release. ]
-
perldelta - what is new for perl v5.13.1
=head1 DESCRIPTION
L<perl5120delta>, which describes differences between 5.10 and
5.12.
-=head1 Notice
-
-XXX Any important notices here
-
=head1 Incompatible Changes
=head2 "C<\cI<X>>"
=head1 Core Enhancements
-XXX New core language features go here. Summarise user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
-
=head2 Exception Handling Reliability
Several changes have been made to the way C<die>, C<warn>, and C<$@>
object-based warning as an object, where previously it was passed the
result of stringifying the object.
-=head1 New Platforms
-
-XXX List any platforms that this version of perl compiles on, that previous
-versions did not. These will either be enabled by new files in the F<hints/>
-directories, or new subdirectories and F<README> files at the top level of the
-source tree.
-
=head1 Modules and Pragmata
-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here. If Module::CoreList is updated, generate an initial draft of the
-following sections using F<Porting/corelist-perldelta.pl>, which prints stub
-entries to STDOUT. Results can be pasted in place of the '=head2' entries
-below. A paragraph summary for important changes should then be added by hand.
-In an ideal world, dual-life modules would have a F<Changes> file that could be
-cribbed.
+=head2 Updated Modules
=over
The implementation of C<Errno> has been refactored to use about 55% less memory.
There should be no user-visible changes.
