Saw a post that [@last] not working on 5.0 on Windows 10. Can confirm it also does not work on OS X.

What Squiffy's version you used?

Oh, you updated it on OS X! I'm still on 5.0. Will update and retry when I'm home. Thanks!

Err, I guess I was looking at the wrong thing. Could'a sworn it was updated. I'm on 5.0 on a Mac.

I think I'll try the command line version.
