Ralph,

Yes, we made the big move the other day towards the 3.7.0 release.
Basically, we made next into master, so master is tracking the 3.7 API
branch now. You should have noticed the ~1100 updates when you pulled
master.

All blocks and code that come with GNU Radio should work fine (we're
bug testing, so reports on bugs in out blocks are welcome). So
anything you have that uses only GNU Radio blocks should update fine,
as long as updated any of the 'old' blocks with the newer ones.

I just sent another message to the listserv about this. All external
GNU Radio projects must be updated to work with the 3.7 API. I've
already started this with gr-osmosdr, including the interface to
RTL-SDR. See the gr-next branch on this repo:

Why does it take an hour to build? Can't you run a parallel make? Even
using -j2 should cut the time down to about half that.
