As Google ramps up the pace seemingly ever day on updates its beginning to seem like it might be less tiresome to run CM nightlies. Android just released another update only a few weeks after releasing 5.1. The new update will bring your device up to 5.1.1. We are still waiting to find out what exactly changed in this new version of Android. I have a feeling that we will see mostly bug fixes.
CyanogenMod took to twitter today to announce that 5.1.1 source code will be included in tonight's nightlies.
Head to the link below to see if your device is supported yet by CM for 5.1.1
