About this issue

@dgorodnichy @Maychell Oh, derp – this is only available on the master branch, this isn’t in a release just yet.

When do you expect to release a stable version with the optional method? 🙏

Upvote, waiting for the stable release 😃 👍

@mkalygin @jasonperrone Yes, I’d advise using the master branch if you really need this.

We still have some open issues for 4.0.0.
