Get ready to start downloading, as the CyanogenMod team has started pushing out its first release candidate for 10.1. The CM team only uses the RC moniker to describe software that is believed to be stable and reliable enough for regular daily use. If you are looking for a rock solid version of Android 4.2 for your phone, this is probably the one to get.
The timing is no coincidence, as this lands exactly one week before a new version of Android is expected to be announced at Google I/O 2013 (probably v4.3). As with previous OS releases, the CyanogenMod team usually pushes a final RC or stable release shortly after the launch of a new version from Google, immediately before integrating the latest code base with their own modifications.
