The CyanogenMOD team has developed stable builds of the newest CM10 software. The latest modded ROM is stable, but has only been confirmed for a select number of devices. The stability, not surprisingly, is directly connected to how much information the CyanogenMOD team have about each device. Smartphones and tablets powered by Qualcomm chips seem to be pretty good, for example, because Qualcomm is forthcoming with its proprietary libraries. By contrast, Samsung isn’t saying much about their Exynos family of chips.
Moving forward, even though stable builds of CM10 are only becoming available now, the team has already started work on CyanogenMOD 10.1. This even newer version of the custom ROM will be based on Android 4.2 Jelly Bean. There are only a handful of new features, so they don’t feel that this newer version quite warrants being called CM11 just yet. We’ll have to wait on one built upon Key Lime Pie for that.
In the meantime, you can go to get.cm to look up your device and see if they’ve got a stable CM10 build for you. As always, loading custom ROMs and any other kind of hackery are done at your own risk and discretion.[Source]
