Kudos on the active development - the commit activity shows real dedication!
The ask: Tagged releases with semantic versioning (e.g., v1.0.0) + a CHANGELOG.md file.
Why it would be valuable: Allows teams to pin to stable versions, breaking changes become predictable via CHANGELOG, easier to track what's new between versions, standard practice for production dependencies, easier to report/fix bugs against specific versions, and GitHub releases provide clear download points for users.
