CyanogenMod 12.1 ROM
Android 5.1 CyanogenMod 12.1 Nightlies rolling out to a spate of Android devicesYouTube

The CyanogenMod (CM) team has just started rolling out its first batch of CyanogenMod 12.1 Nightly ROM builds to a bunch of Android devices including Google Nexus 7 2013 (LTE), OnePlus One, Motorola Droid Razr, Droid Razr HD, HTC One Max, Nexus 4 (aka mako), Nexus 6 (aka Motorola Shamu) and more.

As the nightly builds of CM12.1 ROM are still under development, it might take some time for the CM team to roll out the official milestone builds, which are far more stable than the nightly or experimental builds of CyanogenMod.

The good news is that the CM12.1 ROM can be installed on top of existing CM12 ROM. But, on the downside, all third-party add-ons such as Google Apps (Gapps) need to be installed manually after verifying the Gapps version compatibility with Lollipop firmware as the CM12.1 ROM is based on Android 5.1.

The nightly builds of CM12.1 ROM will be updated on a day-to-day basis until a new final version is eventually rolled out to supported Android devices.
