Jarkko Hietaniemi has released perl 5.7.1 (the link will be active within a few hours if it is not now), the second development release of perl 5.7, which is the development track for what will be perl 5.8. Read the announcement from the archives.
This is NOT perl 5.6.1. perl 5.6.1 is a maintenance release for the stable perl 5.6. perl 5.7.1 is for development purposes only, not for production use. This release sees lots of Unicode changes; PerlIO as the standard instead of standard IO, which is no longer standard; and lots of other cool little things.
