The diagram seems to suggest that 2.4.0 would be first maintenance release. Anyways... So I will be able to make an inplace upgrade from 2.4.0 to 2.4.1 when it is released. i.e. no re-installation of OS or reformatting OSTs when I move to 2.4.1. Just upgrading the Lustre Kernel and Lustre Packages to 2.4.1 should do. right? Yes, that is the meaning of a maintenance release. Any upgrade from Lustre X.Y.N to X.Y.N+1 will not require re-formatting. However, we track vendor kernel bug fixes in our kernels, so a maintenance release will require a kernel change, but should not impact the OS install otherwise.

The 2.4.0 release is one of the 6-month feature releases. 2.4.1 will be the first maintenance release on that branch.
