-[ 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 v5.19.6
=head1 DESCRIPTION
If you are upgrading from an earlier release such as 5.19.4, first read
L<perl5195delta>, which describes differences between 5.19.4 and 5.19.5.
-=head1 Notice
-
-XXX Any important notices here
-
=head1 Core Enhancements
-XXX New core language features go here. Summarize user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
-
-[ List each enhancement as a =head2 entry ]
-
=head2 $a and $b warnings exemption
The special variables $a and $b, used in C<sort>, are now exempt from "used
CPAN modules to provide functions using $a and $b for similar purposes.
[perl #120462]
-=head1 Security
-
-XXX Any security-related notices go here. In particular, any security
-vulnerabilities closed should be noted here rather than in the
-L</Selected Bug Fixes> section.
-
-[ List each security issue as a =head2 entry ]
-
-=head1 Incompatible Changes
-
-XXX For a release on a stable branch, this section aspires to be:
-
- There are no changes intentionally incompatible with 5.XXX.XXX
- If any exist, they are bugs, and we request that you submit a
- report. See L</Reporting Bugs> below.
-
-[ List each incompatible change as a =head2 entry ]
-
=head1 Deprecations
-XXX Any deprecated features, syntax, modules etc. should be listed here.
-
=head2 Module removals
-XXX Remove this section if inapplicable.
-
The following modules will be removed from the core distribution in a
future release, and will at that time need to be installed from CPAN.
Distributions on CPAN which require these modules will need to list them as

=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.
