M1 or nightly builds for many devices are ready for flashing
Falling right in schedule with the halting of development on CM 10.2, CM 11 M1 has just been released for Nexus devices. The latest release of a new version of CM is usually marked by the start of nightlies, but things are a bit different this time around. Because there are likely to be few bugs with the latest version on Nexus devices (excluding the Galaxy Nexus this time around), CM 11 for these devices will be open to bug reports and tweaks to benefit upcoming CM 11 releases for other devices.
Those other devices will start to receive standard nightly builds of CM 11, and because they're early on in development and are likely to have major bugs, you won't be able to immediately submit bug reports — that will come later as the changes settle down. Once usage picks up on nightly builds, we'll see proper M1 and M2 releases for non-Nexus devices.
You can head to the CM download page to see if your device has a CM 11 build ready to go at the second source link below.
