CyanogenMod could very well be the most popular custom Android build around today and thus, many experts have getting a constant flow of attention from developers, tinkerers and android-enthusiast all-around.
The latest 12.1 version from the OS has finally got out with the source code realm and also on to actual device builds. So if your handset currently supports CyanogenMod 12, it is most likely updatable to 12.1, that is, in reality, depending on the AOSP version of Android 5.1. This brings the widely accepted custom ROM current, seeing how Android 5.1 happens to be being seeded to Nexus devices, also.
Even also, Cyanogen developers promise which the new version is directly installable over a pre-existing CM 12.0 install, so no data loss should happen. There is a catch, though - all alternative party add-on zips have to be manually updated running properly. So the challenge is definitely finding the proper, Android 5.1 compatible versions that don’t crash around the new OS.
On another CyanogenMod-related note, a number of you might remember an up to date scoop in regards to a partnership between Microsoft and CM, boiling into the integration of MS apps and services straight to the custom ROM. The whole story was quickly debunked, but Cyanogen took the liberty of reiterating this along with the newest builds announcement.
So, with this fiasco officially out with the way, you can happily enjoy CM 12.1. But, if you undertake hop on the new edition, we will just remind you, it's a nightly build and thus, bugs of the caliber are required. So, in case you rely heavily with your CyanogenMod-powered device, you should probably wait for an more stable milestone build to turn up in the near future.
Also, the state download page for that custom ROM happens to be down, so you could possibly have to look a bit later for that package.
