Detailed release notes follow.

Important new features:

GRC Bus Ports (Nicholas McCarthy)

Bus ports in the GNU Radio Companion (GRC) allow ganging block
input

or output ports into a single port for display and connections.
This

simplifies flowgraph entry when dealing with blocks that work with
an

arbitrary number of
streams.

For further information, see:

http://gnuradio.org/redmine/projects/gnuradio/wiki/Busports

Has gruel been removed from gnuradio?

It is not included in versions 3.7.0 or 3.7.1

Unfortunate if gruel been dropped because neither source or binary files
are available for arm or armhf devices.

This negates the possibility for owners of arm or armhf devices to
compile and install gr-ais which depends on gruel.

Thanks.

Sorry about this separate post, a supplement to my last, but I cannot
edit the post even though it has been much longer than 15 minutes since
it was posted.

Is this the new location of gruel in the file structure?
/usr/local/lib/python2.7/dist-packages/gru Does not seem plausible to
me since the included features produced from cmake do not include gruel.
But, no harm in asking…

Thanks.

Greetings,

Just a quick note that I have now updated the gqrx/snapshots PPA to
GNU Radio 3.7.1. The repository supports i386, amd64 and armhf
architectures.
