I would like to know where the difference between Slurm versions around 2.X.X and 13-15.X are.
The most detailed list I could find regarding versioning is here: http://www.schedmd.com/#news
It seems that with Slurm version 2.6.1 another version named 13.12.0-pre1 came out.
However, nowhere is explained, how these two versions differ from each other.
While the version 13.X is still under development (currently 15.X), it seemed to have stopped for Slurm version 2.6.7.
Are these two different versions compatible to each other? Are upgrades from 2.X to 15.X possible? Are these versions completely diffferent? And if so, in what do they differ?
