First Yosemite update should fix some of the more pressing bugs.



From ArsTechnica:

Apple has just released OS X 10.10.1, the first major update to Yosemite. The patch doesn't include any big new features, but it fixes a handful of bugs, including one that could cause problems with Wi-Fi connections. The update was released alongside iOS 8.1.1, a minor update that improves performance on older devices like the iPhone 4S and iPad 2.

You can grab 10.10.1 through the Mac App Store's Update tab, and it ought to show up on Apple's downloads site later today if you prefer to manually download and install.
