Re: [VOTE] Release Apache Ant 1.10.14 based on RC1

Hello Gary,

Yes, that allow.class which was introduced in 1.10.13 is no longer part 
of Ant 1.10.14. I think, as you note, adding it to the release notes 
sounds like the right thing, since a couple of projects had specifically 
run into issue with that class. I'll update the release note after the 
voting completes (won't create a new RC for that).
