CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Reporting Bugs

You are allowed to report bugs only in this thread. Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow.
