If I remember correctly (and I may well not) it's somewhat OS dependent, with OS X being rather strict about package updates (2.15.1 not being so compatible with 2.15.2) while linuxen are nicer about it. Certainly packages with significant compiled code (like Matrix) are more prone to versioning mis-matches.
