I can read perfectly fine, so a release that is not a release when it is customary to increment the number of the build to avoid confusion, yet somehow when I asked that question I knew I would get asshole responses to it as is customary around here...
Sorry everyone, I was planning on releasing 2.4.4 literally today [...] So if you're willing to download and build from git, now is a good time because the tree is quite stable.
New changes:
Massive overhaul of the nrolltime mechanism now should cause a huge rise in efficiency on pools that support it. This allows much lower getwork bandwidth for much higher hashrates.
Support for the expire= feature. This works in concert with nrolltime when pools support it to allow more local generation of work.
Support for the x-mining-hashrate feature. I'm sure some pool somewhere cares about this, even though I'm not convinced, but it was trivial to add.
Better damping of GPU temperature changes should cause much less overshoot when temps rise or fall outside the optimal range in autofan mode.
Reinstated the application restart should adl fail - disabling this did not fix the crashes for those who had cgminer crash after 1 week of uptime in windows fail land when their ATI driver would fail, and disabled the advantage of it fixing the problem for those who simply lost their fanspeed.
API groups features - this is squarely aimed at grouping privileges for remote access for services like P4man's hopping puppetmaster service.
Support for unlimited devices
Support for unlimited pools
Massive fix for the "dynamic" feature for GPUs. Somehow in the many device abstractions it had gotten broken and wasn't really doing what it was intended. It should be much more dynamic now.
Lots of other things under the hood.
Enjoy.
