The CyanogenMod team has announced the availability of the first nightly builds of CyanogenMod 13, which is based on Android 6.0 Marshmallow.
CM13 is currently available for download only to seven devices, that include OnePlus One, Nexus 7, LG G4, Galaxy Tab Pro 8.4, LG GPad 7.0, LG G3 (Verizon) and Moto X (2014).
Normally, nightly builds are not stable in comparison to the Snapshot releases. The CyanogenMod team recommends that people who have CM 12.1 YOG4P or CM 12.1 YOG7D releases should stick to the Snapshot release and not flash their devices to CM13 nightly build. However, those who are willing to download the latest build can do so, but there will be some quality issues.
CyanogenMod suggests that the team is working on a CM13 Snapshot release that is expected to be made available by January 2016.
"If you are on a 12.1 nightly, you can 'dirty flash' CM13 (read update like any sane person) as long as you also update your third party add-ons in the same pass. This means, if you use Xposed, OpenGapps, etc. flash a Marshmallow compatible version of them immediately after your CM13 flash," per CyanogenMod team.
The team also recommends that if users have any unofficial, self-made or XDA builds of the CM13 source code, then they should delete them completely before downloading the nightlies.
CM13 will bring a number of new features, such as Fingerprint sensor and Multi-Window support to Android devices. It will also bring a new user interface design and keep the app drawer that is also a feature on CM 12.1. Google introduced new app drawer in Android 6.0 Marshmallow and it allows users to organize apps in alphabetical order.
CyanogenMod ROMs are known for better battery backup in comparison to stock ROMs due to the absence of bloatware app on it. Android 6.0 Marshmallow will improve battery backup by two times when compared to Android Lollipop. This means that CM13 will also bring improved battery backup in its upcoming ROMS.
CyanogenMod said that only a select number of devices are in CM13 roster. Although, other Android device owners should keep watch because the availability of CM13 nightlies for their devices might be announced one of these days, hopefully.
