  • scipy 1.11

Maintenance

• Include conftest.py in MANIFEST.in so sdist can run tests propertly (#451)
• Disable linting github action and rely on pre-commit.ci instead (#451)

Highlights

• Add support for Python 3.11 (#423)
• Allow Numba to be optional (#423)
  • User-defined functions (UDFs) still require numba
• Update how to install python-graphblas and dependencies via pip.
  • The recommended way to install python-graphblas via pip is now:
    • pip install python-graphblas[suitesparse] (also installs suitesparse-graphblas)
    • pip install python-graphblas[suitespars-udf] (also installs numba)
    • pip install python-graphblas[default] (also installs pandas and scipy)
    • pip install python-graphblas[all] (installs every optional dependency including for testing and viz)
  • pip install python-graphblas will keep its current behavior for about a year
    • This currently installs suitesparse-graphblas and numba, which may be dropped as required dependencies in 2024.3.0
    • Release 2024.3.0 or later will probably only depend on numpy, donfig and pyyaml
