[USRP-users] [UHD] Release Announcement

Excellent & Happy New Year to the UHD / Volk / GNU Radio community!

For OSX (Mac OS X / macOS) users, I updated the 'uhd' port in MacPorts to
this release last night; it is available right now!

We (MacPorts developers) recommend doing the following semi-regularly to
keep your 'ports' install up to date -- which right now will include
updating 'uhd' (and, if you use GNU Radio, then 'volk' too to the recent
2.1.0 release. I am striving to -finally- update the GNU Radio ports in
early January 2020 so-as to provide GR37, GR38, and GR39 options where
possible and available):
sudo port selfupdate
sudo port upgrade outdated
For most MacPorts users (generally: those using OSX 10.11 or newer), the
"install" and "upgrade" commands will download pre-compiled binaries, and
hence will be quite fast and reliable overall compared with building from
source. UHD / Volk / GR work fine on the current macOS release (10.15
Catalina) -- at least when installed via MacPorts!

I recognize that MacPorts isn't everyone's preference for a package
manager. I do not (yet) develop for HomeBrew or Fink ... because in my
experience MacPorts works more safely, more reliably, and overall better.
That said, if you want a pre-compiled and downloadable OSX GNU Radio .app,
check out @ktemkin's here: <
https://github.com/ktemkin/gnuradio-for-mac-without-macports >. I don't
think it includes the new UHD or Volk releases yet, but I've no doubt it
will in the near future.

Cheers! - MLD
