Since 4.4.0 is already released, people who will install 4.3.1 won’t be able to upgrade to 4.4.0 as the 4.4.0 artifacts won’t have an upgrade path from 4.3.1 to 4.4.0; but this can be only fixed (i.e. have an upgrade path) in 4.4.1. For 4.3.1, we can still have the changes but 4.3.1 users would only be able to upgrade to 4.4.1 or later releases and not 4.4.0 because there is no path from 4.3.1 to 4.4.0 in 4.4.0 release. This is true for all ACS releases, only the latest releases know and have upgrade paths. So, what I also proposed here was to refactor the whole upgrade logic as a tool and maintain it separately and this tool can perhaps has its own release process that is faster than the ACS releases and this tool knows about all the releases and has the necessary upgrade paths.
