So in the Compatibility release notes for 9.1 we should say:

required, users should request transaction isolation mode

Yeah, we definitely need to mention it in the release notes. I feel
there should also be notes in the regular docs, but Heikki would
(quite understandably) prefer to minimize changes to the current
patch until it is committed and deal with that such issues in
smaller follow-up patches.
By all means, feel free to add a note to the docs about this. A note in
the Hot Standby Caveats section would be good, in addition to somewhere
in the chapter about isolation levels.
