Excellent update, very speedy on upgrades now. Amazing what a little (safe) concurrency will do.

Homebrew.app, however, has a show-stopper for me. "Failed to decode Homebrew JSON output" on the installed/upgrades panel. I'm guessing the Discover panel would normally indicate which Formulae/Casks are already installed, but because it couldn't parse the JSON output, that feature (if it exists) doesn't work.

I'll file an issue—I know HN isn't your bug tracker :)

Edit: there's an issue there already, and I sorted out the root cause: iTerm2's shell integration. If you're using zsh as your shell, the solution is here [^0] in the second comment.
