Resolves #6055

[jdvala]

Is there any timeline on when this will be released?

[efiop]

@jdvala We'll likely release by the next monday. Thank you for your interest! 🙏

@efiop I hope this is released soon, we are having a lot of troubles in our CI due to fsspec for s3fs and dvc.

Would you mind sharing those troubles? There is no active DVC release with s3fs yet, so there shouldn't be any issues with it (unless you are installing it separately to the environment dvc is installed).

So the thing is that we are using s3fs (not a direct dependency, dask is using s3fs) in a different project and then importing that project into the current one where DVC is being used, this is type of cyclic dependencies are really a pain to resolve with the new pip resolver (takes ages).

I ran pipgrip on my repo and here is the output

Error: Because no versions of s3fs match >=0.9.0,<2021.4.0 || >2021.4.0,<2021.5.0 || >2021.5.0
 and s3fs (2021.4.0) depends on fsspec (==2021.04.0), s3fs (>=0.9.0,<2021.5.0 || >2021.5.0) requires fsspec (==2021.04.0).
And because s3fs (2021.5.0) depends on fsspec (==2021.05.0), s3fs (>=0.9.0) requires fsspec (==2021.04.0 || ==2021.05.0).
And because my-repo (0.0.3) depends on s3fs (>=0.9.0)
 and dvc[s3] (2.1.0) depends on fsspec (==0.9.0), my-repo (0.0.3) is incompatible with dvc[s3] (2.1.0).
And because . (0.1.dev36) depends on both dvc[s3] (==2.1.0) and my-repo (==0.0.3), . is forbidden.
So, because no versions of . match <0.1.dev36 || >0.1.dev36
 and root depends on . (*), version solving failed.
