I've been happily using this package for a while, then noticed that Package Control was suggesting I upgraded from version "unknown" to the latest. It appeared to succeed, but the package remained in the list of packages with available upgrades.
I removed the package (using PC) and reinstalled (using PC). Again, PC reported success but the package was not actually available.
I notice you don't mention Package Control in your install instructions. Is there a known problem?
(I'm falling back to hg4subl for now, which is working fine, but wanted to let you know about this.)
ST version 2.0.2, Package Control v2.0.0, OS X
