CyanogenMod, the open-source operating system for smartphones and tablet computers, has released the official version of CyanogenMod 13.0 which is based on Android 6.0 Marshmallow builds.

The CM 13.0 also CM 13.0 release 1 includes March security updates and new release builds which are expected to arrive every month.

Along with the goodness of Marshmallow features such as battery-saving Doze functionality, app permissions and more, the CM 13 brings its own tweaks to give users a better experience. For starters, it gets rid of encrypted Whisperpush text messages and fingerprint recognition extends beyond locking the home screen to specific apps .

  • CM Protected apps: New folder UX for viewing protected content

Along with the change logs, the Cyanogen blog also warns users that the CM13 Release 1 series comes with some restrictions and they have to follow a particular procedure to install the new custom ROM depending on the device's current software. For instance, those already running the CM 13 nightly builds should not install the latest release as the nightly is already running the latest codebase (Android 6.0.1_r22). If they still go ahead and do so, the system will crash as it will see this as an attempted database downgrade. For more procedural information click here.

CyanogenMod is developed as free and open source software based on the official releases of Android by Google, with added original and third-party code. Of late, a lot of people have taken to CyanogenMod as it offers features and options not found in the official firmware distributed by mobile device vendors.
