CM 10.2 nightly builds will continue as CM 11 work begins
The latest stable release of CyanogenMod, version 10.2, is now available. While this marks the availability of the custom firmware based on Android 4.3 for dozens of different device, it is also the point where the CM team starts looking forward to KitKat. As is usually the case with big stable releases, active development time will start to focus on CM 11, which will be based on Android 4.4, as fewer and fewer changes need to be made to the 10.2 release.
Also tossed into the announcement of CM 10.2 is the point that CM nightly builds based on ICS (CM 9) will be halted so that newer versions — 10 and higher — can be actively released. Much like the slowing work on the stable version of 10.2, continuing to pump out new nightly builds of older CM branches makes less sense as very few meaningful changes are being consistently made to them.
For now, if you've been waiting for the official "stable" release of CM 10.2 in lieu of using a release candidate or nightly build, now's the time to do so. Downloads of CM 10.2 builds are already starting to be available from CyanogenMod's website at the second source link below. For those who wish to stay on the bleeding edge, CM 10.2 nightlies will continue to roll as CM 11 development moves along as well.
