You seem to be missing this file in the branch:

doc/src/sgml/html/release-11-3.html

It's in the 11.3 tarball.

review: Needs Fixing

[Andreas Hasenack (ahasenack)]

I skimmed the changes declared in the release file, and nothing jumped out as being incompatible or bad, so +1 once the release file issue pointed out earlier is sorted out.

[Andreas Hasenack (ahasenack)]

Oh, and I kicked the bileto tests. Still running, and I suspect it will take a while.

[Christian Ehrhardt  (paelzer)]

Thanks for kicking the tests on all of them.
