0.7.3

• Improvements to the 2D backend calculations
• Added array size thresholds for handing off to serialized fill methods

0.7.2

No real changes; minor release to fix conda-forge build on macOS

0.7.1

No real changes; minor release to fix MANIFEST.in for conda-forge builds.

0.7.0

• OpenMP is now required to build from source (not a difficult dependency to satisfy)
  • omp function argument deprecated
  • omp_max_threads renamed to omp_get_max_threads to mirror OpenMP C API
  • omp_available function removed
• Backend C++ code for 1D histograms rewritten (use Python and NumPy C APIs directly, no pybind11), more types supported (avoid conversions)
• Rewrite multiweight histograms (still via pybind11) to support more types (avoid conversions)
• Python code moved to the top level module (__init__.py) (without changing public API)

0.6.1

• OpenMP inspection improved; new functions replace pygram11.OPENMP:
  • pygram11.omp_available() -> bool checks for availability
  • pygram11.omp_max_threads() -> int checks for the maximum available threads
• some documentation improvements
• bump pybind11 version to 2.4.3
• pygram11.OPENMP will be removed in a future release

0.6.0

This is the first release dropping Python 2 support

• Add type hints
• Improve documentation

0.5.2

• In the backend we replace std::unique_ptr<T[]> with std::vector<T> for on-thread arrays.
• Improved documentation.

This is the last release supporting Python 2

0.5.1

• Fix setup.py such that setuptools doesn't try to install numpy via easy_install (remove unnecessary setup_requires argument).
• Add _max_threads attribute to pygram11._core.
• Fixed macOS wheels (use delocate to ensure OpenMP symbols are bundled).

0.5.0

New features

• histogramming multiple weight variations in a single function call is now possible via fix1dmw and var1dmw
• In the NumPy like API, passing a 2 dimensional array to the weights argument will use this feature as well.
• Binary wheels for Linux and macOS are provided on PyPI (conda-forge binaries are of course still available as well)

Other updates

• All functions now return the sqrt(sum-of-weights-squared) instead of sum-of-weights; before v0.5.x the 2D functions returned the sum of weights squared.

0.5.0.a2

Second 0.5 series alpha.

• Added fixed bin one dimensional multiweight histogramming to front end Python API.
• Updated documentation
