Hi,

since this is new ABI change announcement, and not one that was previously
announced and is now being applied, this announcement should go in the 
deprecation.rst file, rather than release_16_04.rst.

Thomas, is there some reason why the deprecation notices are not called out in
the release notes for a new release? Why are they kept separately?
