Subjectivity is (fortunately?) no longer needed with Mac OS X 10.5 Leopard. Leopard’s mail client dutifully warns senders of blank subject lines before sending mail. I am, for this reason, stopping active development. This built in feature will likely be more useful as it is there by default. So with this release, I’ve fixed up the installer a bit, this time a shell script instead of an AppleScript, and prevented it from trying to install on Leopard. A bit of a farewell for this piece of software–on to bigger and better things.
