The Android ROM community isn't quite as active as it was a few years ago with Android itself becoming more feature-rich. Still, CyanogenMod is chugging along with support for a ton of devices and a reasonably fast update cycle. A new snapshot build of the Marshmallow-based CyanogenMod 13 is now official (ZNH5Y), and it will be available on the first wave of devices today.

You can check out the exhaustive full changelog here if you want, but there's also a changelog of the most important stuff.

  • Wi-Fi Tethering – automatically turn off hotspot after X minutes of inactivity
  • Profiles – add notification light controls
  • Do Not Disturb/Priority Mode – add notification light controls
  • Privacy Guard/App data usage – Restrict apps to Wi-Fi or Cellular data only or block all internet access, per app
  • Bluetooth Devices battery support – For compatible devices, a new battery icon will appear in the status bar to show the paired devices’ battery level
  • Lockscreen Wallpaper picker makes its return
  • Lockscreen Weather and new Weather plug in support – see weather blog post
  • Lockscreen Blur support (on a per device basis) and the ability to disable the effect
  • Live Lockscreen support
  • New LiveDisplay hardware enhancements and API
  • Snap Camera (per device basis)
  • Gello Browser (per device basis)
  • Lots of translations – shout out to the CM translations team on CrowdIn
  • Cyanogen Apps support (see blog post, x86 is not supported yet)
  • Additional CM SDK APIs
  • Security fixes galore

This is a snapshot build, meaning it's the most stable build of CM you can get. Of particular note, this version of CM will include all security patches up through the August bulletin. Build ZNH5Y also includes fixes for several of the recently reported Quadrooter kernel vulnerabilities. Two of the vulnerabilities aren't accessible to the CM team, so those patches need to come from further up the chain.

If you're running the ZNH0E snapshot build, you can flash the new one on top of it. ROMs for various devices will roll out as they are ready. Today, you can expect downloads for popular devices from OEMs like OnePlus, Samsung, and Motorola, as well as most Nexus devices. The full list is available on CM's blog post, but they're all code names.
