There's one, actually. The default pack-index version is increased now,
so really, really old clients (pre-1.4.5) won't be able to understand
the packs generated by default by a new server. I haven't examined how
and when this affect clients, although I believe only those using an
ancient client that fetch pre-created packs over dumb transport (http
or rsync) repo packed with pack.indexversion = 2, or with 1.6.0
without a pack.indexversion setting at all, will suffer.

Encountering that particular scenario should be very rare indeed.

Apart from that, I agree with Jeff about there not being any problems
regarding compatibility, and I wholeheartedly agree with the hint to
start reading the releasenotes.

As for suggesting future improvements, perhaps relnotes entries with
the slightest chance of breaking anything for anyone could be marked
"COMPAT" or something, so Perry and the likes of him can find them
easily. I also agree with the suggestion that git itself should be
free of a deprecated way of doing things at the deprecation date.
