Changelog

0.5.2

  _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_.

0.5.0

---

• 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_.
