The big Paranoid Android 5.1 update has arrived for those with Nexus-branded smartphones and tablets. Based on Android 5.1 Lollipop, the release brings lots of new features and improvements, including Wi-Fi calling on the Nexus 6, a brand new Theme Engine, and VoLTE on select devices.

Cyanogen this week began rolling out its latest CyanogenMod 12 nightlies, which bring some “much needed” new features, including dynamic Quick Settings tiles and Wi-Fi priorities. The releases also bring IMAP push improvements that promise to improve battery life and networking usage.

A new custom ROM for the HTC One M9 brings a number of exciting Lollipop features that aren’t yet built into the handset’s firmware by default. Among them is support for multiple user profiles and native display color controls, and you can get your hands on them now.

MultiROM, the popular tool for Android devices that allows users to install and boot between multiple ROMs, is now available for the Nexus 6, making it easy to switch between Google’s stock software, CyanogenMod, Paranoid Android, or another ROM of your choice on the fly.
