v0.4.0 (2025/08/03)

  • Use XArray for handling IDL format data.

v0.5.0 (2025/08/05)

  • Use Polars for storing test particle data.

v0.5.3 (2025/08/13)

v0.6.8 (2025/11/07)

  • Make the native AMReX particle loader into a module.

v0.6.9 (2025/11/09)

  • Add transform to plot_phase.

v0.6.10 (2025/11/09)

  • Support B and E field velocity transformations.

v0.6.11 (2025/11/11)
