CyanogenMod v7.0.3 Released With Bug Fixes and Security Update
The most popular series of custom ROM’s has received yet another major update. CyanogenMod v7.0.3 and v188.8.131.52 depending on the device, include a very important security fix. The CyanogenMod team highly recommends the update for any user currently running versions 7.0 7.0.2 or 184.108.40.206 releases. There is a catch, if you are currently using a cm7.1 nightly build, do NOT update to v7.0.3.* as the fixes are already included in any build after May 4th. Downgrading from a v7.1 nightly build (Android v2.3.4) to a v7.0.* stable release (Android v2.3.3) is known to cause issues. The update to v7.0.3.* also includes a bug fix for the notification system.
