Just after expanding Nightly support to Samsung's Epic 4G and a slew of LG handsets, the CyanogenMod team has brought nightlies to a handful of Xperia devices, including Coconut (the Xperia Live with Walkman), Iyokan (the Xperia Pro), and Satsuma (the Xperia Active).
In a Google+ post earlier today, CyanogenMod announced that CM7 support had arrived for multiple new devices, throwing out a special hint to Xperia users.
For those not familiar, a "nightly" is a brand new released, built on a daily (or nightly) basis with a day's worth of new code. Often times, new features contained in nightly updates may be unstable or not fully tested. The features in nightlies often evolve into alphas, betas, RC's and at some point make it into a full, stable release.
