Wrong, it *is* bumped.
Look at today's conversation between me and BtBn where he gives link to
the merge commit of ffmpeg.
I think Michael takes care of bumping version numbers when merging libav
features (for example libav bumped from 51.24 to 51.25, and FFmpeg from
51.41 to 51.42 for cpu flag mask)

No patching at all is done, Michael uses MICRO number >= 100 in all
