I think the users that screamed about this would like a detailed "every
user visible change" list, in addition to the highpoints Release notes.

And having guidelines for the developers that describe the simple
questions to ask themselves when answering 'does this deserve a release
note'. It's not about advertizing: it's about documenting changes, so the
DBA can grep for likely words of something breaks, such as (in this case)
"array".

Tom, you said 'every change is user visible'. I think, for this purpose,
only things that modify existing behavior (input or output) in kind,
not merely quality, are 'visible'. A patch that speeds up (or slows
down!) query processing by 100 fold is certainly user visible, but not
for the purposes of reporting release changes. New functionality is not
'user visible'.
