CyanogenMod have released CM9 RC1 for 37 devices. The core OS has been stabilized for these 37 devices as developers are now looking to fine tune whatever bugs might’ve been left out earlier. The devices not included in the 37 list will continue to be worked upon to achieve the RC1 stage. Users who have downloaded the RC1 ROMs and are experiencing issues can report them here at the issue tracker for CM9. You can download the RC1 for you device (if available) here.
