Matroftt helped us find out where our sudden stars were coming from. Very thankful to get a flurry of appreciation from the community today for CorsixTH :)
I suppose I can answer a few questions about the history.
Peter Crawley (Corsix) built the original versions of CorsixTH back in 2009. I made my first significant contribution in 2012 when I added movies. Now I am the oldest active contributor and Windows packager. I primarily work on the engine and leave the scripting to others.
Lewri joined in 2020 and brought a lot of energy back to the project, improving community outreach, bug triaging, patching and keeping everyone talking.
Alan runs the distinct but parallel Android port which was recently started again after a long hiatus.
A number of other developers are currently active and can be found in our discord/matrix channel.
