This will most likely be the last update to JSB. A lot of you won't even be able to update to this version, but you should see this message. Apple is no longer allowing this type of extension to exist in Safari. If you'd like to let Apple know just how much you need extensions like JSB, you can leave feedback here:

It's sad to say goodbye. I appreciate everyone who has ever used JSB and am incredibly grateful for all the support I received.
