If you've been sitting on pins and needles waiting for the community-focused CyanogenMod firmware to both make the leap to Android 5.1 and fix that nasty Stagefright MMS exploit, you can relax. Hot on the heels of Cyanogen OS 12.1 (for devices like the OnePlus One), CyanogenMod 12.1 is arriving with both the perks from Android 5.1.1 as well as a Stagefright patch thattheoretically keeps you safe. There are also Stagefright fixes for CyanogenMod 11 and 12.0, in case you can't run the new operating system right away. There are a lot of devices to cover with this rollout, so don't be alarmed if you don't see a download right away -- if your phone or tablet is already running CyanogenMod's decidedly non-standard code, there's probably an update waiting in the wings.
