But 9.3.0 is not mentioned in
    https://gcc.gnu.org/develop.html#timeline
- the closest is "GCC 9.3 release (2020-03-12)".

The distinction between 9.3 and 9.3.0 is meaningless to you,
but that is what has caused Heime's confusion.

You are saying that X.Y is a release and that X.Y.Z is something else,
but then use X.Y.0 to refer to a release.

Even though I cannot remember when Z != 0 last appeared,
gcc --version reports a string of the form X.Y.Z
so it seems to me that X.Y.Z *does* need to be described,
and the .0 should be included in the timeline.
