v3.16.0

2026-09-27

• #604: Fixed duplicate_iterators=True for async functions spied with mocker.spy.
• #611: Fixed async mock assertion introspection to use awaited arguments instead of the latest call's arguments.
• #606: mocker.resetall(return_value=True, side_effect=True) now also applies to non-callable mocks, such as those returned by mocker.create_autospec(SomeClass, instance=True). Previously both arguments were silently ignored for them.
• #547: Added SpyType for annotating mocker.spy results.
• Dropped support for EOL Python 3.9.
• #147: Removed handling of RuntimeError: stop called on unstarted patcher, which can no longer occur in the supported Python versions.
• Added support for Python 3.15.
