Generally speaking, there shouldn't be any problems between two
versions that have the same minor version (the scheme is
major.minor.patchLevel).  Also generally speaking, it is a good idea
to have your software as consistent as possible.  Upgrading from 4.0.x
to 4.0.y should be a safe upgrade.  Upgrading from 4.x to 4.y might
have some caveats (ie, options that have been added or removed since
the last minor version).

Peace and Blessings,
