I first set up Known on one of my DreamHost sites in 2016-2017, around the time of the first Distributed Web Conference. Have been running on 0.9.2 for quite some time, maybe since then.
Today I finally upgraded to 1.0.0 and the experience went very well.
I should probably turn off the non-https version of my Known blog and set it up so it's https-only, but I'm afraid that might be complicated.
Thanks for Known, congrats on the 1.0.0 release, and thanks for making the upgrade easy.
Crossing fingers for continued success.
