CyanogenMod has announced today on their website as well as their Google+ page (pictured above) that CM9 stable builds will be popping up. I assume this is for all their RC2 ROMs they have on the site.
A post on their site revealed some other information such as Jelly Bean development and what these stable builds mean for Ice Cream Sandwich.
If your running a CyanogenMod nightly release or Release Candidate for a CM9 release, I advise you to head over to the CyanogenMod site and grab the stable build for your phone.
Now that CM9 is finished, we expect a ton of CM10 nightly builds. I was already running Aeroevan’s Unofficial CM10 build for the Incredible 2. It was the lightest and most responsive ROM i have ever flashed on my phone. If your phone had a CM9 build then expect a CM10 ROM to play with in the near future.
