I understand your reason for making these changes. However, I am unsure
if your new wording is as clear as the previous one. Our reliance on
Cygwin and inability to prevent an error from aborting a transaction
were limitation and it seems clearer to just state that we have fixed
them rather than try to sugar-code our previous limitations.
Marketing-wise, I think you are right, but from an honesty/clarity
perspective, I think the current wording is better. What I could do is
remove some of the later references where we were talking updating the
system catalog to do various things. I am not sure it is needed.

It is mentioned as the top item in the pg_dump section. It doesn't seem
like a migration issue to me though. Is it a major feature?

We can improve the wording, but if the motivation is to reduced saying
bad things about our previous functionality, let me explain my
Basically, my goal with these release notes is to make it as clear as
possible why this new feature would be valuable to the reader. If it
makes our previous release look bad, so be it. For me, clarity and
candor gain a lot more credibility than trying to cover over missing
functionality in the past. I am not saying we have to be so honest that
we bash PostgreSQL, but in cases where we adjust wording to try to
prevent ourselves from looking bad, it is best to be honest and clear
about our limitations. I think in the long run it gains us lots of
credibility (and ultimately volunteers).
