Hello! 👋
I am trying to upgrade our app from 0.11 to 0.13.1, and it seems parTupledN and parMapN has been moved and is now deprecated.
Is there documentation on how I could resolve this? Thank you!

Hey @Attila Domokos,

I'm not sure if you saw the release post? https://www.47deg.com/blog/arrow-0.13.0-release/

parMapN was renamed to parZip and now includes CoroutineScope as receiver in the lambdas.
And tupledN was removed in Arrow Core to remove redundant aliases, so we followed the same in Arrow Fx Coroutines.

So you can refactor to parZip({ fa() }, { fb() }) { a, b -> Pair(a, b) }.

Hope that helps 👍

Thanks @simon.vergauwen, I tried to bump Arrow to 0.12 and that had a pointer to parZip. I'll check the release notes.

I had to use nested parTupledN calls with v0.11.0 and now with parZip it's a lot cleaner! 🎉
