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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Nightlies: http://get.cm/?device=jfltexx

We have de-unified the Galaxy S4 line. Too many issues with having them all in one and a maintainer's nightmare. Look for jfltexx builds now as opposed to the jflte builds you previously used.

Google Apps:

OpenGApps (choose ARM, 5.1, nano)

The CyanogenMod team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!
