- Drop support for Python 3.6, which reached end of life on 2021-12-23
   and is no longer supported by pip as of pip version 22.
   Take advantage of this to reduce bidict's maintenance costs.
 - Use mypy-appeasing explicit re-exports in ``__init__.py``
   (e.g. ``import x as x``)
   so that mypy no longer gives you an implicit re-export error
   if you run it with ``--no-implicit-reexport`` (or ``--strict``)
   against code that imports from :mod:`bidict`.
 - Update the implementations and type annotations of
   :meth:`bidict.BidictBase.keys` and
   :meth:`bidict.BidictBase.values` to make use of the new
   :class:`~bidict.BidictKeysView` type,
   which works a bit better with type checkers.
 - Inverse bidict instances are now computed lazily the first time
   the :attr:`~bidict.BidictBase.inverse` attribute is accessed
   rather than being computed eagerly during initialization.
   (A bidict's backing, inverse, one-way mapping
   is still kept in sync eagerly as any mutations are made,
   to preserve key- and value-uniqueness.)
 - Optimize initializing a bidict with another bidict.
   In a microbenchmark on Python 3.10,
   this now performs over **2x faster**.
 - Optimize updating an empty bidict with another bidict.
   In a microbenchmark on Python 3.10,
   this now performs **60-75% faster**.
 - Optimize :meth:`~bidict.BidictBase.copy`.
   In a microbenchmark on Python 3.10,
   this now performs **10-20x faster**.
 - Optimize rolling back

- update to 0.22.0:
- Drop support for Python 3.6, which reached end of life on 2021-12-23
and is no longer supported by pip as of pip version 22.
Take advantage of this to reduce bidict's maintenance costs.
- Use mypy-appeasing explicit re-exports in ``__init__.py``
(e.g. ``import x as x``)
so that mypy no longer gives you an implicit re-export error
if you run it with ``--no-implicit-reexport`` (or ``--strict``)

:meth:`bidict.BidictBase.keys` and
:meth:`bidict.BidictBase.values` to make use of the new
:class:`~bidict.BidictKeysView` type,
which works a bit better with type checkers.
- Inverse bidict instances are now computed lazily the first time
the :attr:`~bidict.BidictBase.inverse` attribute is accessed
rather than being computed eagerly during initialization.
(A bidict's backing, inverse, one-way mapping
is still kept in sync eagerly as any mutations are made,
to preserve key- and value-uniqueness.)
- Optimize initializing a bidict with another bidict.

- Optimize updating an empty bidict with another bidict.
In a microbenchmark on Python 3.10,
this now performs **60-75% faster**.
- Optimize :meth:`~bidict.BidictBase.copy`.
In a microbenchmark on Python 3.10,
this now performs **10-20x faster**.
- Optimize rolling back
:ref:`failed updates to a bidict <basic-usage:Updates Fail Clean>`
in the case that the number of items passed to the update call
can be determined to be larger than the bidict being updated.
Previously this rollback was O(n) in the number of items passed.
Now it is O(1), i.e. **unboundedly faster**.
- Optimize :meth:`bidict.BidictBase.__contains__`
(the method called when you run ``key in mybidict``).
In a microbenchmark on Python 3.10,
this now performs over **3-10x faster** in the False case,
and at least **50% faster** in the True case.
- Optimize :meth:`bidict.BidictBase.__eq__`
(the method called when you run ``mybidict == other``).
In a microbenchmark on Python 3.10,
this now performs **15-25x faster** for ordered bidicts,
and **7-12x faster** for unordered bidicts.
- Optimize :meth:`~bidict.BidictBase.equals_order_sensitive`.
In a microbenchmark on Python 3.10,
this now performs **2x faster** for ordered bidicts
and **60-90% faster** for unordered bidicts.
- Optimize the
:class:`~collections.abc.MappingView` objects returned by
:meth:`bidict.OrderedBidict.keys`,
:meth:`bidict.OrderedBidict.values`, and
:meth:`bidict.OrderedBidict.items`
to delegate to backing ``dict_keys`` and ``dict_items``
objects if available, which are much faster in CPython.
For example, in a microbenchmark on Python 3.10,
``orderedbi.items() == d.items()``
now performs **30-50x faster**.
- Fix a bug where
:meth:`bidict.BidictBase.__eq__` was always returning False
rather than :obj:`NotImplemented`
in the case that the argument was not a
:class:`~collections.abc.Mapping`,
defeating the argument's own ``__eq__()`` if implemented.
