Perl

Perl is an open source, stable, and cross-platform programming language.

The Perl project is used for mission critical projects in the public and private sectors and is widely used to program web applications of all needs.

What is new in this release:

• Changes to Existing Documentation:
• perlrepository has been restored with a pointer to more useful pages.
• perlhack has been updated with the latest changes from blead.
• Selected Bug Fixes:
• Perl 5.18.1 introduced a regression along with a bugfix for lexical subs. Some B::SPECIAL results from B::CV::GV became undefs instead. This broke Devel::Cover among other libraries. This has been fixed. [perl #119351]
• Perl 5.18.0 introduced a regression whereby [:^ascii:], if used in the same character class as other qualifiers, would fail to match characters in the Latin-1 block. This has been fixed. [perl #120799]
• Perl 5.18.0 introduced a regression when using ->SUPER::method with AUTOLOAD by looking up AUTOLOAD from the current package, rather than the current package's superclass. This has been fixed. [perl #120694]
• Perl 5.18.0 introduced a regression whereby -bareword was no longer permitted under the strict and integer pragmata when used together. This has been fixed. [perl #120288]
• Previously PerlIOBase_dup didn't check if pushing the new layer succeeded before (optionally) setting the utf8 flag. This could cause segfaults-by-nullpointer. This has been fixed.
• A buffer overflow with very long identifiers has been fixed.
• A regression from 5.16 in the handling of padranges led to assertion failures if a keyword plugin declined to handle the second ‘my', but only after creating a padop. This affected, at least, Devel::CallParser under threaded builds. This has been fixed
• The construct $r=qr/.../; /$r/p is now handled properly, an issue which had been worsened by changes 5.18.0. [perl #118213]
