Pyflagser

=============

Major Features and Improvements
-------------------------------

- Wheels for Python 3.10 are now available (`70 <https://github.com/giotto-ai/pyflagser/pull/70>`_).
- Wheels for Apple Silicon are now available for Python versions 3.8, 3.9 and 3.10 (`70 <https://github.com/giotto-ai/pyflagser/pull/70>`_).
- A ``MANY_VERTICES`` compilation flag has been added to enable computations on graphs with more than 2^16 vertices (Florian Unger, `68 <https://github.com/giotto-ai/pyflagser/pull/68>`_).

Bug Fixes
---------

- A bug in ``save_unweighted_flag`` has been fixed (Florian Unger, `69 <https://github.com/giotto-ai/pyflagser/pull/69>`_).

Backwards-Incompatible Changes
------------------------------

Python 3.6 is no longer supported, and the manylinux standard has been bumped from ``manylinux2010`` to ``manylinux2014`` (`70 <https://github.com/giotto-ai/pyflagser/pull/70>`_).

=============

Major Features and Improvements
-------------------------------

- Wheels for Python 3.9 have been added.
- The ``flagser`` submodule has been updated to the latest upstream version, integrating the following changes:

- ``flagser`` now trows exceptions instead of exiting the computation;
- ``flagser`` now supports a number of threads as input parameter and, by default, it will use the maximum number of logic cores available.
- ``flagser`` no longer produces output files.

Bug Fixes
---------

An error encountered when running multiple instances of ``pyflagser`` in parallel (due to clashes between temporary file names) has been fixed.

=============

Major Features and Improvements
-------------------------------

- ``flagser_count_unweighted`` and ``flagser_count_weighted`` were added to provide fast computations of simplex counts per dimension.
- ``flagser_unweighted`` and ``flagser_weighted``'s performance was improved when ``coeff`` is 2 by using a compiled version of C++ ``flagser`` without the ``USE_COEFFICIENTS`` flag.
- All C++ library files were moved to ``pyflagser/modules/`` upon compilation.
- The documentation of ``flagser_unweighted`` and ``flagser_weighted`` was further improved.
- Python bindings were made clearer, and documented for future maintenance.

Bug Fixes
---------

- A bug was fixed which caused ``flagser_unweighted`` and ``flagser_weighted``'s output persistence diagrams to be of shape ``(0,)`` instead of ``(0, 2)`` if empty.
