Server Operations needs to validate Github Enterprise version upgrades in a test environment, prior to performing them on the production github.mit.edu environment. Furthermore, we allow our key customers (MITx and the Ops internal infrastructure group) an opportunity to validate that the new version meets their needs, and this sometimes takes some time.
Here's the current known schedule for future versions:
|Version||Test Status||Deploy Status|
|2.9.15||Deployed Summer 2017||Current Production|
|2.11.7||In Testing Dec 2017||Current Test|
|2.11.7||Planning Production upgrade||TBD|
