So there is no place to discuss anything that's posted in the 7.6.1 changes thread? That's strange.
Click on the link at the bottom of each reposted/mirrored item, and discuss the changes at that link. That's where the most current information regarding UBB.threads development (currently at v7.6.1) are happening. On the Developer site, UBBDev.com
From the OP:
these changelog notes are being mirrored from UBBDev.com
A link at the end of each post will take you to the discussion regarding that specific changelog.
