Perl 5.10 Release Candidate 2 has been released, two (busy) weeks after the RC1. As Dave Mitchell, the 5.10 pumpking, says, I'm not planning to change anything between now and final release unless it's a real showstopper; so, help making sure there are no showstoppers left before the final release!
As usual, the full list of changes is in the perldelta; and here is a list of significant fixes since RC1:
Please report any problems you encounter, especially bugs introduced since 5.10.0. Whenever possible, please report bugs using the perlbug utility. If the build or regression tests fail, make nok. If the build fails to early to run this, please mail perlbug at perl.org directly.
