Release v1.0.0 (#68) - all normalized string_metrics can now be used as scorer for process.extract/extractOne - Implementation of the C++ Wrapper completely refactored to make it easier to add more scorers, processors and string matching algorithms in the future. - increased test coverage, that already helped to fix some bugs and help to prevent regressions in the future - improved docstrings of functions - Added bitparallel implementation of the Levenshtein distance for the weights (1,1,1) and (1,1,2). - Added specialized implementation of the Levenshtein distance for cases with a small maximum edit distance, that is even faster, than the bitparallel implementation. - Improved performance of `fuzz.partial_ratio` -> Since `fuzz.ratio` and `fuzz.partial_ratio` are used in most scorers, this improves the overall performance. - Improved performance of `process.extract` and `process.extractOne` - the `rapidfuzz.levenshtein` module is now deprecated and will be removed in v2.0.0 These functions are now placed in `rapidfuzz.string_metric`. `distance`, `normalized_distance`, `weighted_distance` and `weighted_normalized_distance` are combined into `levenshtein` and `normalized_levenshtein`. - added normalized version of the hamming distance in `string_metric.normalized_hamming` - process.extract_iter as a generator, that yields the similarity of all elements, that have a similarity >= score_cutoff - multiple bugs in extractOne when used with a scorer, thats not from RapidFuzz - fixed bug in `token_ratio` - fixed bug in result normalisation causing zero division

Installation
============
While there are several ways of install RapidFuzz, the recommended methods
are either by using `pip` (the Python package manager) or
`conda` (an open-source, cross-platform, package manager)
using pip
---------
RapidFuzz can be installed with `pip`:
.. code-block:: sh
pip install rapidfuzz
There are pre-built binaries (wheels) of RapidFuzz for MacOS (10.9 and later), Linux x86_64 and Windows.

<div class="admonition error">
<p class="admonition-title">failure "ImportError: DLL load failed"</p>
<p>
If you run into this error on Windows the reason is most likely, that the
<a class="reference external" href="https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads">Visual C++ 2019 redistributable</a> is not installed, which is required to
find C++ Libraries (The C++ 2019 version includes the 2015, 2017 and 2019 version).</p>
</div>
using conda
-----------
RapidFuzz can be installed with `conda`:
.. code-block:: sh
conda install -c conda-forge rapidfuzz
from git
--------
RapidFuzz can be directly used from GitHub by cloning the

repository. This requires a C++14 capable compiler.
