Moving right along to Mason I 0.15 RC3 after the failures of RC2. I believe those issues were directly linked to the inclusion of lulzactive, which is conspicuously absent on this one. Other optimizations have been made, and it's starting to lean out as one would expect when pushing towards a version release.
I think I'm at a feature freeze as far as 15 goes at this point. It's time for clean up, the compile is still quite dirty, and there are a couple rough edges to clean out.
