Taking a breather from all the work on L, we snuck in another M release yesterday against the CM 11.0 (KitKat) branch. This release is less heavy on features, instead focussing on stability for various device trees and security fixes.
Notably on the security topic, this release incorporates the upstream Google patches against last months POODLE vulnerability in SSLv3. You can read more about the POODLE vulnerability on Google’s Security Blog. Users are strongly encouraged to update to the latest available build to keep in line with the latest security patches.
