Behaviour of MonadCancelThrow[EitherT[IO, Throwable, *]]

This issue sounds somewhat familiar, and apologies if I forgot the exact discussion, however I stumbled on it in the wild in the context of https://github.com/typelevel/fs2/pull/2895 and found it pretty...

Proposal: IO#raceMany that accepts collection of IO[T], returns winner and cancels others

I've been considering a race scenario implementation for a collection of IOs. Concept itself is similar to IO#race but stretched out to many IOs. Input is a collection of IO[T]....

Unsafe run sync in CE3

Use `js.typeOf` checks for JS feature tests instead of try/catch

This is my fault. I've been lazily using `Try(js.Dynamic.global....)` when I should be writing idiomatic code like this: https://github.com/typelevel/cats-effect/blob/76d2602ea651a6f0035bef4f9aa506773a335c95/std/js/src/main/scala/cats/effect/std/JavaSecureRandom.scala#L77-L78 Today in the Discord there were reports of `ReferenceError: Can't find...

Using the same primitives implemented in #2885, implement a higher performance `circularBuffer` for `Async[F]`. This will probably require some fiddling with `UnsafeBounded` to allow it to run in overwrite mode...
