    • is_generator_specific.
    • is_technicolor.
    • is_composite_quark_or_lepton.
    • is_special_particle.
  • Several PDG ID qualification functions improved and/or enhanced,
    and minor bugs fixed for certain special particles.
• Data CSV files:
  • Version 7 of package data files, with fixed LaTeX and HTML particle names.
  • Added newly-ish defined particles for two-Higgs-doublet scenario
    and additional SU(2)xU(1) groups.
  • Internal and user-irrelevant file particle2008.csv file removed.
• Tests:
  • Test suite extended to deal with new PDG ID related functions.
• Documentation:
  • Demo notebook slightly extended.
  • More explanations in the functions qualifying PDG IDs.

  • Added the 2020 PDG data table .mcd file, now default.
  • Version 6 of package CSV data files:
    • Since PDG 2020 information now the default.
    • Bug fix in parity of antibaryons.
• Documentation:
  • README updated and expanded with info on custom data loading.
• Miscellaneous:
  • ZipApp fix for releasing from web interface.

Version 0.10.0

  • Several improvements, in particular to better deal with nuclei
    and diquarks.
  • Speed of table loading improved.
  • Particle enums extended for diquarks.
  • Make particle literals available from top-level import.
  • Print-outs made more consistent for missing and non-relevant
    particle properties.
  • New tests added, some static type checking.
• PDGID class:
  • PDG ID functions extended to correctly and consistently deal
    with nuclei.
  • Functions now accept any SupportsInt, including Particle objects.
• Data CSV files:
  • Version 5 of package data files:
    • Diquarks added.
    • Information in nuclei added! List and masses taken from
      package periodictable version 1.5.2.
    • A couple of PDG ID numbers corrected (they had evolved in
      time).
  • Converter script adapted to add to the produced data files
    particles not in the PDG data table, such as diquarks.
• Redesigned packaging system, GHA deployment.
• Miscellaneous:
  • Files *requirements.txt removed from package - use
    pip install .[dev] instead
  • Warning from collections.abc fixed, keeping compatibility with
    Python 2.
  • Deprecation warning in attr.s fixed, requirement on minimal
    version of attr added.
  • Version tags now follow standard v#.#.# format.
  • Some Python warnings fixed, warnings enabled on testing
  • Some initial work on static type hints.
  • ZipApp fixes, simplifications and size reduction; ZipApp now
    requires python3 to be available
