Comment(by michaelld@…):

 Yes, Yes.  3.4.1 was released just last week; it's on my long queue of
 things to do.

 Question: Some of the gnuradio-* ports (which are still around) were
 removed from the 3.3.0 distro (e.g., gnuradio-mblock, which was part of
 3.2.X). Given that we're now to 3.4.X, can I just remove those ports?  Or,
 should I put a stub in place that just tells the user some relevant
 message but installs nothing?
