We'll likely be preforming the UBB.Threads upgrade (from v7.5.3 to 7.5.6) sometime this afternoon. There will be a small "hiccup" period as this upgrade is pushed out.

EDIT:
'eh decided that since I had already hacked the files this early that rolling out the update wasn't really too much of a hassle...

So, upgrade to what should be the last in the UBB.Threads 7 Series is now complete.
