Releases
Every version of the editor and the engine, with what changed in it. The one to follow if you build on Polygonjs and want to know what a new download brings.
Feeds
Everything we publish is a feed you can follow in your own reader. No account, no newsletter, and nothing that tracks you back.
Blog
Longer writing: how a part of the engine works, what a release was actually for, and the occasional thing we got wrong. Slower than the releases and worth more per post.
Atom is the format every reader written this century understands. JSON Feed is the same content for anything easier to wire up from code. Both carry the same entries, so subscribe to one, not both.
