PyAutoGalaxy v2026.4.13.3

What's New

Breaking Changes

  • refactor: rename env vars to PYAUTO_* prefix (#343)
    • One env var rename. Quantity visualizer now controlled by PYAUTO_SKIP_VISUALIZATION instead of PYAUTOFIT_TEST_MODE. See full details below.
  • fix: give each basis independent ell_comps in mge_model_from (#342)
      • New parameter: centre_per_basis: bool = False on mge_model_from — when True, each basis gets independent centre priors
      • Behaviour change: mge_model_from with gaussian_per_basis > 1 now produces independent ell_comps per basis (was previously tied). Calls with gaussian_per_basis=1 are unchanged.
  • refactor: merge PYAUTO_DISABLE_CRITICAL_CAUSTICS into PYAUTO_FAST_PLOTS (#340)
    • Environment variable only — no Python API changes. PYAUTO_DISABLE_CRITICAL_CAUSTICS is retired; set PYAUTO_FAST_PLOTS=1 instead to skip both tight_layout() and critical-curve/caustic overlay computation. Callers that only set PYAUTO_DISABLE_CRITICAL_CAUSTICS will no longer skip overlays — they must migrate to PYAUTO_FAST_PLOTS=1.
    • Paired PyAutoBuild PR removes the retired flag from the release workflow, default env vars, and docs. A follow-up workspace sweep will remove it from the autofit/autogalaxy/autolens workspace env_vars.yaml, run_scripts.sh, and CLAUDE.md files.
  • feat: reinstate title_prefix on all matplotlib subplot panel titles (#333)
  • refactor: remove integral-based deflection/potential methods from mass profiles (#324)
    • The following methods are removed from mass profile classes:
      • deflections_2d_via_integral_from — removed from Gaussian, Sersic, SersicGradient, NFW, gNFW, gNFWSph
      • deflection_func — removed from Gaussian, Sersic, SersicGradient, NFW, gNFW
