When was 4.6 released?

Roughly two years ago.

thank you legendruthless.
My follow-up would be: is there a place I can access in regards to the development of 4.7? to be observational/interested, and without participation?

He doesn’t have anything we can see. Last update was he was working on a new interface instead of 4.7.

Prior to version 4.6 he had a road map so everyone could follow his plans. But that is hidden nowadays
