There is not only a
Version 7.6.0 Changelog thread here at
UBBCentral, which lists all of the major changes coming in v7.6.0, which was last updated on November 7th, but there is also the
Official UBB.threads Announcements forum at
UBBDev was last updated on November 5th (Development of UBB.threads v7.5.9+ is done through
UBBDev).
Live coding of v7.6.0 is running at both here at UBBCentral and UBBDev as a public beta test of the code itself. Development is anything but dead, with weekly/monthly changelogs which show drastic changes in the codebase (this is a MAJOR rewrite), things are actually quite active; especially when one takes into account that the development team has day jobs and other outside obligations.
Plus, you know, the hints that we've been working on the Installer/Upgrade tool in the shoutbox and various postings...
