If you're reading this on a later GSM-only Samsung device, pay attention. After clarifying their continuing support for Tegra 2 devices earlier this week, the CyanogenMod ROM team wants to let you know about their position vis-à-vis Samsung's Exynos 4 series of chipsets. In a nutshell: devices based on the Exynos 4 will be getting CyanogenMod 10.1 (Android 4.2) nightly builds, and not much else. These phones and tablets will not be getting stable releases of the latest CyanogenMod builds for the time being.

Here's a quick list of the affected devices, running the Exynos 4210 and 4412 chipsets:

Galaxy S II (AT&T and International GSM)

Galaxy S III (International GSM)

Galaxy Note (International GSM)

Galaxy Note II (AT&T, T-Mobile, International GSM and International LTE)

Galaxy Note 10.1 (WiFi and International GSM)

The CyanogenMod team's reason for the lowered level of support includes "various issues surfacing from the binaries and sources we have to work with." According to this Google+ post, they've been having issues since Ice Cream Sandwich, and no longer feel they can meet their own high standards for stable builds. If they can iron out the problems they'll upgrade these devices, but that doesn't seem particularly likely.

Support for the Exynos 3 and Exynos 5 will continue, based on the source codes for the Nexus S and Nexus 10, respectively. (Also, if you've got a Qualcomm Snapdragon-powered Samsung phone or tablet, like most of the US versions not listed above, you're in the clear.) The CyanogenMod team is actively working on the Exynos 5 Octo-core platform, based on the international Galaxy S4.
