No, not all X.Y release are compatible. For instance, the current
version is 4.1, 4.0 is still supported. 4.2 will come out in a couple
of months. I currently have a 4.0 box that needs to be upgraded. I
could 'upgrade' to 4.1, but not to 4.2. To go to from 4.0 -> 4.2 I will
need to reinstall.
For most everything, when you upgrade you end up replacing all the
binaries. A kernel from a new version will generally run the userland
apps from the previous version, but the userland apps from a new version
will generally NOT run on the previous versions kernel.

All openbsd releases that have the same "major" version are definately
OpenBSD's versions are not major.minor they are just numbers. 3.9 to
4.0 was not a 'major' milestone, it was just the next version.
Every 6 months a new version of OpenBSD is released and they just
increment the number by .1. Going from 3.0 to 4.0 was 10 releases over
