CyanogenMod 11 M12 snapshot is rolling out as we speak, because the most popular ROM must keep the good work up and update ALL the Androids of the world! The snapshot build started rolling out yesterday and, by now, most devices should be ready for it. You can get your update from the update menu or from the CM download page.
The CyanogenMod snapshot or the M build is the main ROM version for users, being also the most stable build available. The M builds are the ones you would want to use to keep your device as safe as you could when it comes to a custom built ROM.
The update is a few megabytes in size so you can head on and get it for yourself. It has bug fixes and little updates, as well as some security tweaks. Of course, you will be getting more support for dual SIM.
