Default How to recreate my stable releases using manifests

I want to build a stable 4.4.2 omni, but omni codes in github had updated to 4.4.4, and I do not know how to roll back.
In CM, there is always a build-manifest.xml in its rom and I can easily roll back to the status defined by build-manifest.xml (

Then I wonder how can I get the xml file to obtain the same repos as you guys in a stable release?
