##### 📢 Version Discrepancies  

We released a bad version 4.0.2 due to being in the middle of a typescript refactor during a patch release. Due to this the release versions and tags have gotten a bit out of wack. I was branching off of tags for 4.0.3 and 4.0.4 to avoid the same issue from 4.0.2.  

For simplicity's sake I've reverted the TS refactor and `master` is even with the latest 4.0.4. I have removed tags/releases for 4.0.2 and 4.0.3. React 19 peerDependencies are up to date in 4.0.4.

Sorry for the confusion!
