Are Nightly CyanogenMod Releases Safe? I am using a 2013 Moto X Developer Edition (XT1053) and am currently running stock Android, (with the exception of Motorola's software) and I am thinking of switching to CyanogenMod. However, after looking at the CyanogenMod download releases for the "ghost" model, I notice there are pretty much only nightlys. I have never used a nightly release before, and I do have a nandroid backup if anything goes wrong, but are the nightlys stable enough to use daily?
Back when I had a Samsung Galaxy Ace and wanted to use CyanogenMod on it, it almost always had a Nightly build. Encountered a few bugs, but not major ones.

Granted this is a different phone and CM version, point is you have to know which features/functionalities are working and not based on the wiki/release notes provided. Also which bugs are present. You may want to wait for those information to be available before flashing. But it's always good to have a Nandroid back up.

So, nightlys could be safe, could be not. Always refer to the documentation.
