Consider adding tags for the repo.

[Piicksarn]

Hi @botelho~

Your great work had been recommend being added in CDNJS.
However, we need tags for repo to specify points in history and mark release points.
It's helpful for user to know the version and status of repository, and would enable wider distribution of the library.
Would you please consider on using tags?

Thank you!
