Re: CVS commits and logs

[Richard Stallman]

      Exception: it is okay to
        commit several changes to a single ChangeLog file in one "cvs ci"
        command if those changes are related to the same feature/bugfix.

It's ok to commit unrelated items together in a ChangeLog file.

Aside from that, I agree with your rules.

    One other rule: the date label of the ChangeLog entry should reflect
    the date on which the change was _committed_ (as opposed to the date
    when the change was made in someone's local sandbox).

Yes.

      In other words,
    the dates in the ChangeLog should be monotonically increasing from
    bottom to top.

The change log entries should always be in order of most recently
committed first.  As Juanma points out, that doesn't always mean
the dates decrease.
