Contributed by Dan Ailenei in `81 <https://github.com/ionelmc/python-hunter/pull/81>`_.
* Improved contributing section in docs a bit.
Contributed by Tom Schraitle in `85 <https://github.com/ionelmc/python-hunter/pull/85>`_.
* Improved filtering performance by avoiding a lot of unnecessary
``PyObject_GetAttr`` calls in the Cython implementation of :class:`~hunter.predicates.Backlog`.
* Implemented the :class:`~hunter.actions.ErrorSnooper` action.
* Added support for profiling mode (eg: ``trace(profile=True)``).
This mode will use ``setprofile`` instead of ``settrace``.
* Added ARM64 wheels and CI.
* Added :any:`hunter.event.Event.instruction` and :any:`hunter.event.Event.builtin` (usable in profile mode).
* Added more cookbook entries.
