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.

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?

A maintenance release stream is a series of maintenance releases that follows a given feature release. So, 2.4.0 is a feature release, 2.4.x is set to become our next maintenance release stream, and 2.4.1 (due out in Q3) will be the first maintenance release in that stream. The visual on the roadmap showing the link between the feature releases and the maintenance releases aims to illustrate this. Does this make sense? Do you have any suggestions how we could clarify this?

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.

I guess that clears all confusions. Peter, you could simply remove the number '2.4.0' shown in the 'Maintenance Release' branch in the diagram. i.e. not have 2.4.0 printed at both places. This will clearly indicate that 2.4.0 will be a 'Feature Release' but will go on to become a 'Maintenance Release' in its subsequent versions. Thanks Guys.
