Mail Extension, New icon?

Hello! I had to un-install SpamSieve to try and correct a bug; after the re-install, I’m back to using a plug-in for Apple Mail, but I think I’d been using an extension with a newer version…? I’m not sure. A recent update had a newer icon too, but I can’t seem to find a newer version than the current download. I’m thoroughly confused.

Also, the special Junk icon in Apple Mail is gone.

Thanks!

It’s in public beta.
