@cdata The automated tests are failing, do I need to make a change in the configuration?

[nlfiedler]

Excellent, thank you, I'll test and build locally and push out a release.

Just to confirm before I update the changelog, this is not a major change, nor is there a breaking change, correct? From my reading of https://doc.rust-lang.org/cargo/reference/semver.html it looks like a minor change. While the AsyncStreamCDC was modified, it was not in a published release. Was there something else I failed to notice that warrants either a BREAKING CHANGE or a major version bump?

Thanks

@nlfiedler ah, this was my mistake. I did in fact break AsyncStreamCDC but you are correct to point out that it had never been released in the first place. So, as far as releases are concerned, there was no breaking change here.

[nlfiedler]

Very good, it has been released. Thank you again.
