5.10.0-compatible PAR kits are building as I write this.
Some tweaking was needed - that seems to be the case with *every* new version of Perl - but the PAR kits are now happily building. :-)
Given that it's now late Nov., and my original target was for *early* Nov., I think I'll just add the versioner support and call it 1.1.2. If anyone has something you MUST see in 1.1.2, now's the time to send patches for it! :-)
