• When comparing :class:~datetime.datetime or :class:~datetime.time instances, if the fold is the only thing that's different, it's now shown in the output.

• A more detailed exception is now raised when resolving a :doc:replacement <mocking> doesn't give what's expected.

• :doc:Replacement <mocking> of methods on instances is now prevented when strict=True.

• Fix bug where replacement of methods on subclasses failed when using :meth:Replacer.on_class.

• Implement :ref:strict comparison <compare-datetime> as an option for :class:~datetime.datetime and :class:~datetime.time.

• Retire zope.component helpers.

• Support :class:bytes in :class:popen.MockPopen commands.
