Changelog

Sourced from UnitfulAtomic's changelog.

v1.0.0

• Remove unnecessary code in __init__()
• This release contains no breaking changes

v0.3.0

• Update physical constants to CODATA 2018 recommended values (BREAKING)
• Simplify some atomic units (BREAKING):
  • 1st hyperpolarizability: e^3*a₀^3/Eₕ^2
  • 2nd hyperpolarizability: e^4*a₀^4/Eₕ^3
  • E-field gradient: Eₕ/(e*a₀^2)
  • Electric polarizability: e^2*a₀^2/Eₕ
  • Permittivity: e^2/(a₀*Eₕ)
• This release is compatible with Julia ≥ 0.7 and Unitful ≥ 0.16

v0.2.0

• Change names of atomic units to remove name clashes (BREAKING):
  • mₑ → me_au
  • e → e_au
  • ħ → ħ_au
  • k → k_au
  • a₀ → a0_au
  • Eₕ → Eh_au
• Register all units for usage with @u_str
• Compatibility with Unitful 0.14.0 (cf. ajkeller34/Unitful.jl#201)
• Since this version uses the CODATA 2014 recommended values, it does not support Unitful ≥ 0.16

v0.1.0

Initial release. This release only supports Unitful ≤ 0.13.0.
