Thanks a lot to the whole ReScript community for this remarkable achievement, we would not have been able to do this without y’all.

Have fun with the new release!

Thank you for this FANTASTIC and probably most prominent and important ReScript release so far! It’s turning into a mature, stable language with its own identity (and legacy :-)). The effort you put into this is mind blowing - I use ReScript everywhere I can today and I have no clue what I’d do without it any longer (probably leave the Node.js domain behind altogether, it’s unbearable without ReScript for me today).

Thank you so much for this early Christmas gift!
