The bug caused Wi-Fi connectivity to drop intermittently on certain configurations of Macs and routers. Over the course of the month since Yosemite was released, the bug has generated a 1,000-plus reply thread on the Apple support forum.
Mac users that have experienced Wi-Fi performance issues running Yosemite should expect to see an improvement with this update. I've tested it on a system that was affected by the Wi-Fi bug and the problem now appears to be fixed.
According to Apple, the 10.10.1 patch not only addresses the Wi-Fi bug, but a raft of other issues too:

There are also enterprise-related improvements:

And there are also numerous bug fixes, including a lock screen bug that allowed unauthorized access to photos.
