Can we update the tag please?

Hi, we're using the 1.2.0 tag since it was the last released tag.
This tagged release does not have the check for duplicate functionality.
This also fixes #35 which is the issue we had.

Fix:
All you need to do is release the current code as a tag.
You can do so here:

If you want you can make me a maintainer and I can just release it with the new tag as well.
