Ecosystem upgrade megathread

[kubukoz]

Here, we can track the progress of major libraries upgrading to CE3.

That should be a nice way of finding out whether any of them are going to be late with the upgrade, or straight-up impossible to migrate in a relatively source-compatible fashion.

I came here from your tweet 😅
In cats, I did the following doc PR to collect the libs/projects related to the typelevel ecosystem

typelevel/cats#3609

It may be relevant to this thread I guess
Cheers 😉

Can we roll fuuid in to cats-effect-std module?

[kubukoz]

Can we roll fuuid in to cats-effect-std module?

I'm all for it. Also a small Random[F], Chris's unique and https://github.com/ChristopherDavenport/system-effect/blob/master/src/main/scala/io/chrisdavenport/system/effect/Environment.scala

• fs2-grpc has a CE/FS2 3.0 branch with all tests green :)

[kubukoz]

Added, thanks!

[RaasAhsan]

Can we open issues for each library/class we'd like to port to std?

[ChristopherDavenport]

Random - https://github.com/christopherdavenport/random
Cats-Effect-Time - https://github.com/ChristopherDavenport/cats-effect-time (scalajs artifact size complications)

[kubukoz]

@RaasAhsan I like the idea, I can create some later on, unless someone beats me to it

[ghostdogpr]

For ZIO interop, the repo is this one https://github.com/zio/interop-cats

fs2-rabbit has a CE/FS2 3.0 branch with all tests green

catbird seems to be missing from the list (Finch is using it for example).

I tried to implement the new typeclasses but I'm again blocked by cancelation requirements. My thoughts are here: typelevel/catbird#267
