Many thanks to those who have reported bugs, shared ideas, fixed documentation, and submitted patches over the past three months! 👏

We could mention the R.both not short-circuiting anymore change here.

[davidchambers]

Good idea. I've updated the description.

[anton-rudeshko]

R.compose, R.pipe, R.composeP, and R.pipeP no longer return curried functions

😭 my code is exploding now 😢 very very very sad

[ivan-kleshnin]

I also complain about it here: #1391
