The latest version (r60) is not marked as a github release, and they are sporadically spread out. We have r57, r55 and r51 as the three latest whereas I imagine we'd have one for each revision. Additionally, only r51 has the addon zipped with it like a full release.

Would it be possible to more consistently tag releases and uploaded the .zip with the associated tag?

Reasonable request, the problem is that the project is not using the community packager. I could set that up but don't have enough permissions on the repo here to set up environment vars. If @Jaslm is available and can grant me the permissions or set it up, I can do it!
