0.5.2

-----
- fix bug where ``firstresult`` wrappers were being sent an incorrectly configured
``_Result`` (a list was set instead of a single value). Add tests to check for
this as well as ``_Result.force_result()`` behaviour. Thanks to `tgoodlet`_
for the PR `72`_.

- fix incorrect ``getattr``  of ``DeprecationWarning`` from the ``warnings``
module. Thanks to `nicoddemus`_ for the PR `77`_.

- hide ``pytest`` tracebacks in certain core routines. Thanks to
`nicoddemus`_ for the PR `80`_.

0.5.1

-----
- fix a bug and add tests for case where ``firstresult`` hooks return
``None`` results. Thanks to `RonnyPfannschmidt`_ and `tgoodlet`_
for the issue (`68`_) and PR (`69`_) respectively.

0.5.0

-----
- fix bug where callbacks for historic hooks would not be called for
already registered plugins.  Thanks `vodik`_ for the PR
and `hpk42`_ for further fixes.

- fix `17`_ by considering only actual functions for hooks
this removes the ability to register arbitrary callable objects
which at first glance is a reasonable simplification,
thanks `RonnyPfannschmidt`_ for report and pr.

- fix `19`_: allow registering hookspecs from instances.  The PR from
`tgoodlet`_ also modernized the varnames implementation.

- resolve `32`_: split up the test set into multiple modules.
Thanks to `RonnyPfannschmidt`_ for the PR and `tgoodlet`_ for
the initial request.

- resolve `14`_: add full sphinx docs. Thanks to `tgoodlet`_ for
PR `39`_.

- add hook call mismatch warnings. Thanks to `tgoodlet`_ for the
PR `42`_.

- resolve `44`_: move to new-style classes. Thanks to `MichalTHEDUDE`_
for PR `46`_.

- add baseline benchmarking/speed tests using ``pytest-benchmark``
in PR `54`_.  Thanks to `tgoodlet`_.

- update the README to showcase the API. Thanks to `tgoodlet`_ for the
issue and PR `55`_.

- deprecate ``__multicall__`` and add a faster call loop implementation.
Thanks to `tgoodlet`_ for PR `58`_.

- raise a comprehensible error when a ``hookimpl`` is called with positional
args. Thanks to `RonnyPfannschmidt`_ for the issue and `tgoodlet`_ for
PR `60`_.

- fix the ``firstresult`` test making it more complete
and remove a duplicate of that test. Thanks to `tgoodlet`_
for PR `62`_.
