So awesome. Congrats and keep up the great work everyone!

It is appreciated, more than you will ever know.


The .rpm and .deb packages needed to be resigned and uploaded. An old subkey made it way to the signing process, but that should be fixed now. Sorry!

The good news is that the signing should be faster next time. Narrowing the time between the tag and the actual release.

Somehow the wrong key didn’t triggered an issue during the docker images that are been updated also in the next couple of minutes.
