If you are at all familiar with the CyanogenMod team then you have some sort of idea how much time and effort goes into building their custom ROM’s. When ICS came out it posed to be a large task to incorporate all the Android 4.0 goodness on top of adding the CM features and injected butter we all have come to enjoy. CM9 is the teams latest build and has been in the nightly stage for some time now but the team just announced that they are gearing up to release an official RC1 (release candidate). Since the team is ready to build something final, they have recently issued a code freeze. That means although they still plan to release nightly builds, they wont be accepting any new code other than bug fixes and additional device support. What features and extras you see now is what you get, and RC1 will be a polished version of the most recent nightly builds.
As usual, the initial release will support a small number of devices, but more devices will be added in the future. We still don’t know exactly what devices will receive support at launch but you can imagine they are hard at work to release versions for most of the popular devices. Stay tuned for CM9 RC1 because it is just around the corner. Head to the source link for more details.
