I’m sorry about the expiration surprise — didn’t expect to go this long without an update. I give each beta an expiration date so people update when a newer beta or a release version becomes available. I uploaded new betas last night, so if you go to the About Box and check for updates, you’ll get a dialog to download it.
I should have engineered that better. When a plugin expires it should check for an update and should also get the release version if there’s no beta available. If you have other suggestions, please let me know.
