The developers behind the popular CyanogenMod custom ROM for Android devices have released a minor update fixing some of the bugs that have been uncovered since CyanogenMod 7.0 was released two weeks ago. In fact, the developers pushed out two updates last night. But since some bugs were discovered in version 7.0.1, that update was pulled and quickly replaced with CyanogenMod-7.0.2.
Existing CyanogenMod users should get a notification when a build is ready for their device. You can also grab the download directly from the CM web site or use the ROM Manager utility for rooted devices.
The update fixes problems with the app launcher and Google voice on most devices. Some phones also had problems with GPS, proximity and light sensors. This update should fix those problems, among other things. You can find more details in the change log.
