While many users of CyanogenMod have moved on to the nightly Marshmallow-based CM13 releases, the more stable snapshot builds are still on CM12.1 (Lollipop). It's been more than two months since we got a new snapshot build, but now one is starting to roll out.
The CyanogenMod snapshot builds (previously called milestones) are the closest thing to a stable release. They should have the fewest bugs and the best hardware support. Unlike nightlies, which are usually released every night (duh), it can be a few weeks between snapshot builds.
So far, the new build has only been rolled out for a few Motorola devices—the 2013 Moto X, the Droid Ultra/Maxx, and the Moto Maxx variant. You can expect the new build to come to more devices soon.
