Is this a new version? I don’t remember if I bought it or got it through my patron membership, but I do have it already installed on my computer. 
 

Edit: reading more in detail, I’m now aware that the change is that it used to be available exclusively to patrons, but now it’s available to all TG members. Thanks, it’s a great typeface. 

Same version, just made public now. 

I must give thanks for your development and release of these fonts - they're outstanding. I was about to start work on creating OTFs of Signal's flavors myself by hand using FontForge, but wasn't looking forward to the slog :-)

amazing! Thank you, king of type
