Have you thought about syncing git tag with Cargo crate version in Cargo.toml?

My worry is that the tags and version in Cargo.toml can get out of sync. At the very least, we should check if they are in sync before publishing.

Nope, but it's a great idea. Not sure how to do this, though. Are there any other projects that do that already that we can learn from?

I can do some research into it. Not a blocker for this PR though.

Thanks, then I'll merge it.
I think I'll add support for binary releases to Github, too and then cut a new 0.4.0 release.
