So you agree that this behavior worked, for quite some times (years...). And
that it worked as documented.

This means, of course, that the change in behavior was breaking
backwards-compatibility.

Whether you liked the original behavior or not is therefore completely
irrelevant: a backwards-incompatible change has been slipped in, without
appropriate documentation or public announcing, let alone the appropriate
deprecation period.

That is not okay.

Whatever you want to do, do it correctly. Do not just break
backwards-compatibility nilly-willy. And certainly not (maliciously?) snuck
into a "bug fix" release.
