A mashup between reagami and webcomponents. I don't know why you would do this, but you can!

pr-str, prn, etc now print EDN instead of JSON in squint, as you can see in this beautiful draggable button demo

You can't make this shit up. I wanted to implement prn (for printing EDN) in #squintcljs so I created a branch named "prn". But it turns out you can't name a file prn (or prn.extension) in Windows so Windows CI failed.

cannot lock ref 'refs/remotes/origin/prn': Unable to create 'D:/a/squint/squint/.git/refs/remotes/origin/prn.lock': Invalid argument

Out of band DOM updating (manually messing with DOM elements) counter example in Reagami

The on-render hook in reagami just got more awesome. You can now pass data from mount to update to unmount, by just returning data!

Reagami now has an on-render hook that you can use to mount/update/mount a 3rd party JS component.
