Apple has updated OS X Yosemite to version 10.2.2 which is available through Software Update. The update brings a variety of fixes, most notably issues with WiFi connectivity, slow performance in loading webpages, and a security issue with loading remote Mail in Spotlight. iCloud Drive content can now be browsed in Time Machine, the company's local backup solution for OS X. On my MacBook Pro with Retina Display, the update was a sizeable 554 MB download.
