Release candidates for our March release are available at: https://github.com/gnuradio/gnuradio/releases/tag/v3.10.2.0-rc1 https://github.com/gnuradio/gnuradio/releases/tag/v3.9.6.0-rc1
OK, they were tagged in March. A few nice fixes/changes popped up at the last minute, so we let it slide a little. If everything looks good, the final releases will be published in a few days.
