Autobuild is the new Linden Lab framework to maintain and build everything, from viewer to 3rd party libraries.
Channels and Versions
Channels are just groupings of versions. Linden Lab uses channels to track and supply updates for Project, Beta, and Release Viewers separately.
On login, the combination of channel plus version is checked against a set of rules in the Viewer Version Management service. Within each channel, some versions are allowed and some are blocked. Viewers are blocked if they are too old, are unsafe (security issues), incompatible (the protocol has been changed in some fundamental way), or are a test version and Linden Lab only wants data from the most recent. See Viewer Integration and Release Processes for an explanation of how different versions are managed by Linden Lab.
If you are building a viewer, the Policy on Third Party Viewers requires that you set your own channel name.
