Over on the CyangoenMod site, the CM10 team revealed that their latest “M” - milestone or monthly – build of Android 4.1 Jelly Bean has been released. As previously reported, the “M” builds of the popular CyanongenMod 10 firmware are to be the definitive stable versions of CM10. The “M” builds are described as “ready to use as your daily driver” when in comparison to the more common but less stable nightly builds.
As expected the M2 release has become available around a month following the M1′s arrival. M2 builds are now available for a variety of devices including all 3 Galaxy Nexus variants, Galaxy SII models, and all the U.S. Galaxy SIII phones, as well as other devices. The newest builds of CyanogenMod 10 are available via the CM updater, as well as via ROM Manager.and the get.cm download site.
