Perl v5.13.7 released

  {Neo sees a black cat walk by them, and then a similar black
      cat walk by them just like the first one}
  Neo:      Whoa. Deja vu.
  {Everyone freezes right in their tracks}
  Trinity:  What did you just say?
  Neo:      Nothing. Just had a little deja vu.
  Trinity:  What did you see?
  Cypher:   What happened?
  Neo:      A black cat went past us, and then another that
               looked just like it.
  Trinity:  How much like it? Was it the same cat?
  Neo:      It might have been. I'm not sure.
  Morpheus: Switch! Apoc!
  Neo:      What is it?
  Trinity:  A deja vu is usually a glitch in the Matrix. It happens  
              when they change something.

This release corresponds to commit 57fc91ac6f in Perl's git repository. It is tagged as 'v5.13.7'.

We welcome your feedback on this release.

If Perl 5.13.7 works well for you, please use the 'perlthanks' tool included in this distribution to tell the all-volunteer development team how much you appreciate their work.

If you discover issues with Perl 5.13.7, please use the 'perlbug' tool included in this distribution to report them.

If you write software in Perl, it is particularly important that you test your software against development releases. While we strive to maintain source compatibility with prior stable versions of Perl wherever possible, it is always possible that a well-intentioned change can have unexpected consequences. If you spot a change in a development version which breaks your code, it's much more likely that we will be able to fix it before the next stable release. If you only test your code against stable releases of Perl, it may not be possible to undo a backwards-incompatible change which breaks your code.

Perl 5.13.7 represents approximately one month of development since Perl 5.13.6 and contains 73100 lines of changes across 518 files from 39 authors and committers.

Notable changes in this release:

  • Array and hash container functions accept references
  • Improved support for custom OPs
  • Single term prototype
  • Unicode Version 6.0 is now supported (mostly)
  • y///r

I like how the page just showed a bunch of matrix crap instead of any useful information whatsoever

How exactly should the blog parse long ass posts to show what you think is useful? Oh wait, it can't. It just shows the top portion of the post.

Thanks for share
