Release 1.0.0

Major Release Version 1.0.0

• Data files:
  • Added the 2026 PDG data table file, now default,
    and made a new 2026 nucleus data file to match.
  • Added version 16 of package CSV data files since PDG 2026 information now the default.
  • Removed old and superseded 2022 and 2023 PDG and derived data files.
  • Removed old 2020 and 2022 nucleus data files.
• Particle class and submodules:
  • Return Fraction instead of float for charge, spin J, and isospin I.
  • Implemented baryon, lepton and R-parity quantum numbers.
  • Implemented flavour quantum numbers - strangeness, charmness, bottomness, topness. Also hypercharge.
  • Tests added for all new functionality.
  • Added also a test of the Gell-Mann–Nishijima formula relating charge to isospin and hypercharge.
  • Performance improvements, notably for particle and PDGID literals.
  • Minor improvements and fixes to the odd member function.
  • Improvements to the CLI commands python -m particle ... for better user experience
    and clearer error messages.
• PDGID class method and related standalone functions:
  • Return Fraction instead of float for charge, spin J, and isospin I.
  • Minor fixes to the odd function.
• Classes for MC particle identification codes and converters:
  • New common MCParticleID base class for MC particle ID classes.
    The classes Geant3ID, PythiaID, Corsika7ID now inherit from it
    and are much simplified and streamlined.
• Dependencies:
  • Moved to Pandas 2.0+.
  • Dropped support for Python 3.9.
• Miscellaneous:
  • Added support for agents.
  • Started using pattern matching to simplify bits of code.
• Tests and CI:
  • Test suite significantly improved and enhanced.
  • Updates and improvements to pre-commit hooks and CI YAML files.
