This is not really a point release. OCaml versions a little different, a version number has three parts: Super-Major.Major.Patch. Super-Major releases are incredibly rare, the last one was the bump to 4, which was done since the language now supports GADTs (while staying compatible with OCaml 3.x). I don't even know what caused the bump from 2.x to 3.00. Then the Major part is a normal release in which many features may be added. The format is always two digits, of which the first may as well be a 0. The Patch part is just for fixes, stuff that was broken and overlooked when the release was done. So OCaml 4.03.0 is basically 4.3.0 in a Python-esque versioning scheme (remember how many changes were done between Python 2.2.0 and 2.7.0?).
