This could be broken into separate issues if that's more convenient.
Ref gh-240, deprecated/removed stuff for 1.9
Ref gh-240, 1.9 updates for .add()
Ref gh-240, clarify .attr() vs .prop() some more.
We never documented .data()-fired events and I haven't seen any complaints so I'm not going to document they were removed.

Ref gh-240. In 1.9, empty ajax response is not valid JSON.

Updated the exemple to reflect the change in Jquery 1.9 that the Ajax events should be attached to the document.

dmethvin: changed "broadcast" to "trigger" event terminology.
@dmethvin any chance you or someone else from the core team could finish this? "Ordering of disconnected nodes within a jQuery set" is interesting to me, since I recently hit a performance issue involving .add().
Where would be the right place to put the note about ordering? It applies to all methods. I think that .add() needs special notice since it's better to use $([ a, b ]) than $(a).add(b) if you want a specific order.
$([ a, b ])
I'm not sure the best way to document the general rule, but just adding a sentence about the array usage not forcing DOM order is a step in the right direction. We use this in UI when we want to have a manually ordered set.
We can mention that in jQuery() then. Since we got rid of the special behavior of .before() etc on disconnected elements I think .add() is a somewhat unique lone survivor so I can mention it there.
More emphasis about avoiding .add(), ref gh-240
Note new sane 1.9+ behavior for disconnected elems, ref gh-240
Down to just three open tasks, nice.
You can deploy manually to stage to test your changes or show them to others. Not great in the long run, but better then nothing. Ping me elsewhere if you need the credentials.
