Release Candidate 1: I consider this the first stable version that would be ready for public consumption, but it needs additional testing. Especially around the paths that are used for caching comment text and the @excludes (I suspect I'm missing at least one).
added since 0.13 were a couple more fixes
* page scroll now stays where it is no matter how you close the dialog
* keyboard shortcuts aren't shown on screens < 500px to save space
* if the dialog opens outside of viewport (you made your browser smaller) it defaults back to bottom right
* actually deletes any outdated cache, not just for the viewed page
