The code is no longer compatible with older versions of zope.testing
and introduces a hard dependency on a new major release of another
package. That clearly constitues the need for a major version upgrade
in my book.

If the code would optionally use zope.testrunner and fall back on the
existing zope.testing it would be fine to do this change in a minor
release like 1.3. As you can tell from the reported breakage the new
release is not backwards compatible.

Some people use the prefer-final option of buildout to guard against
unstable software. But more importantly humans checking for new
versions or the z3c.checkversions has a chance of identifying this new
release as yet unstable.
