Dear GNU Radio Community,

tonight, we’re releasing the first release candidate for the GNU Radio release.

You can find it on and soon as a tarball on

This is really a major step. In fact, it’s so big, that I really didn’t find the means to write a sensible CHANGELOG; I’ll conclude on the most user-relevant changes in the final release’s entry.

However, I’ve gone through all commits v3.7.0.0..HEAD and tried to count the unique contributors:

I’d like to announce that we’ve got a glorious amount of 215 individual contributors that added at least one commit since 3.7.0 that goes into this release candidate. Johnathan released 3.7.0 on the 29th of June 2013, some good six years ago.

To be specific, that’s 2209 days from today. Which means that we got one unique contributor every 10 days and 6-and-a-half hours. Not too shabby, I’d say, for this enormous period of time.

I’m pretty happy to see that the speed at which new contributors find our way seems to be increasing these days. We’re a lively, high-quality product with what I consider to be one of the more healthy communities you’ll find in Free Software.

Let us ride eternal, shiny and chrome.

Best regards, Marcus
