=encoding utf8 =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.XXX.XXX =head1 DESCRIPTION This document describes differences between the 5.XXX.XXX release and the 5.XXX.XXX release. If you are upgrading from an earlier release such as 5.XXX.XXX, first read L, which describes differences between 5.XXX.XXX and 5.XXX.XXX. =head1 Notice XXX Any important notices here =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 reports are welcome. =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 section. =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 directories, or new subdirectories and F files at the top level of the source tree. =head1 Modules and Pragmata XXX All changes to installed files in F, F, F and F go here. If Module::CoreList is updated, generate an initial draft of the following sections using F, 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 file that could be cribbed. =head2 New Modules and Pragmata =head2 Pragmata Changes =head2 Updated Modules =head2 Removed Modules and Pragmata =head1 Utility Changes XXX Changes to installed programs such as F and F go here. Most of these are built within the directories F and F. =over 4 =item F XXX =back =head1 New Documentation XXX Changes which create B files in F go here. =over 4 =item L XXX =back =head1 Changes to Existing Documentation XXX Changes which significantly change existing files in F go here. Any changes to F should go in L. =head1 Performance Enhancements XXX Changes which enhance performance without changing behaviour go here. There may well be none in a stable release. =over 4 =item * XXX =back =head1 Installation and Configuration Improvements XXX Changes to F, F, F, and analogous tools go here. =head2 Configuration improvements XXX =head2 Compilation improvements XXX =head2 Platform Specific Changes =over 4 =item XXX-some-platform XXX =back =head1 Selected Bug Fixes XXX Important bug fixes in the core language are summarised here. Bug fixes in files in F and F are best summarised in L. =over 4 =item * XXX =back =head1 New or Changed Diagnostics XXX New or changed warnings emitted by the core's C code go here. =over 4 =item C XXX =back =head1 Changed Internals XXX Changes which affect the interface available to C code go here. =over 4 =item * XXX =back =head1 New Tests XXX Changes which create B files in F go here. Changes to existing files in F aren't worth summarising, although the bugs that they represent may be. =over 4 =item F XXX =back =head1 Known Problems XXX Descriptions of platform agnostic bugs we know we can't fix go here. Any tests that had to be Ced for the release would be noted here, unless they were specific to a particular platform (see below). This is a list of some significant unfixed bugs, which are regressions from either 5.XXX.XXX or 5.XXX.XXX. =over 4 =item * XXX =back =head1 Deprecations XXX Add any new known deprecations here. The following items are now deprecated. =over 4 =item * XXX =back =head1 Platform Specific Notes XXX Any changes specific to a particular platform. VMS and Win32 are the usual stars here. It's probably best to group changes under the same section layout as the main perldelta =head1 Obituary XXX If any significant core contributor has died, we've added a short obituary here. =head1 Acknowledgements XXX The list of people to thank goes here. =head1 Reporting Bugs If you find what you think is a bug, you might check the articles recently posted to the comp.lang.perl.misc newsgroup and the perl bug database at http://rt.perl.org/perlbug/ . There may also be information at http://www.perl.org/ , the Perl Home Page. If you believe you have an unreported bug, please run the B 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 C, will be sent off to perlbug@perl.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 perl5-security-report@perl.org. This points to a closed subscription unarchived mailing list, which includes all the core committers, who 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. =head1 SEE ALSO The F file for an explanation of how to view exhaustive details on what changed.
