Thanks.

This depends on the code going into BlueZ first, then into PA, and both
making releases (there are currently a whole lot of changes in master,
so we'd probably need to do a couple of rounds of RCs before shipping a
new stable release).

As Bastien pointed out, they will not be. To make the transition less
painful, our plan on the PulseAudio side is to support both BlueZ 4 and
5 in the short term till there are enough users have migrated to BlueZ 5
and we can feel more confident about dropping BlueZ 4 support.
Fortunately, we are able to separate this out without much in the way of
additional maintenance burden.

I think it makes sense to use this approach with 3.10 as well - support
BlueZ 4 and 5 as a compile-time option for this release, get some more
user-testing during this cycle from the more adventurous, and then
switch to BlueZ 5 only in 3.12
