0.11.2

Renamed internal Python files hist.py and misc.py to _hist.py and _misc.py, respectively.

The contents of these modules are brought in to the main pygram11 module namespace by imports in __init__.py (the submodules themselves are not meant to be part of the public API). This avoids tab completions of pygram11.hi<tab> yielding pygram11.hist when we actually want pygram11.histogram.

0.11.1

Two convenience functions added to the pygram11 namespace:

• bin_centers: returns an array representing the the center of histogram bins given a total number of bins and an axis range or given existing bin edges.
• bin_edges: returns an array representing bin edges given a total number of bins and an axis range.

0.11.0

• API change: functions calls with weights=None now return None as the second return. Previously the uncertainty was returned (which is just the square-root of the bin heights); now users can take the square-root themselves, and the back-end does not waste cycles tracking the uncertainty since it's trivial for unweighted histograms.
• More types are supported without conversions (previously np.float64 and np.float32 were the only supported array types, and we converted non-floating point input). Now signed and unsigned integer inputs (both 64 and 32 bit) are supported.
  • If unsupported array types are used TypeError is now raised. This library prioritizes performance; hidden performance hits are explicitly avoided.
• Configurable thresholds have been introduced to configure when OpenMP acceleration is used (described in the documentation).
• The back-end was refactored with some help from boost::mp11 to aid in adding more type support without introducing more boilerplate. We now vendor boost::mp11 as a submodule.
• Bumped the vendored pybind11 submodule to v2.6.2.
• C++14 now required to build from source.
• Added Apple Silicon support for Python 3.9 with libomp from Homebrew installed at /opt/homebrew.
• Documentation improvements
• Renamed master branch to main.
