Here's the first build from the androidarmv6 jenkins, with CM Updater/OTA support:
xda devdb mirror: http://forum.xda-developers.com/devd...ct/dl/?id=6889
MediaFire mirror: https://www.mediafire.com/?fww9av35wq227fs
Team-Simplicit mirror: http://www.team-simplicit.com/downlo...AL-liberty.zip
I don't think anything liberty-specific has changed except for CM Updater being added.. just upstream CM/androidarmv6 stuff.
The EXPERIMENTAL part in the filename doesn't really have any meaning - that's just how it was built.
Only marvel has been added to the build schedule so far, but I think the other devices will be added soon (I don't want to bug them about it, so I haven't asked yet).
Once that happens, jenkins will build updates weekly that will show up in the updater (Settings > About phone > CyanogenMod updates) or here
Edit: First OTA/weekly is out http://download.androidarmv6.org/_builds/liberty/
[developer stuff ahead]
With this, all of the source has moved to androidarmv6. SimplicityCM still exists, but probably will be used more for testing things or for different ROMs.
