Version 0.4.0 (2026-06)

Major redesign of the curryer.correction package with a new modular architecture, Pydantic-based configuration, standalone verification workflows, GCP regridding support, and expanded documentation and examples.

Highlights

  • Refactored curryer.correction into focused modules – split the former monolithic implementation into dedicated modules: config, pipeline, verification, parameters, kernel_ops, image_io, results_io, regrid, and error_stats.

  • Pydantic-based configuration – introduced structured config models (GeolocationSetup, Sweep, OutputConfig, DataConfig, GeolocationConfig, NetCDFConfig, RequirementsConfig, RegridConfig) with improved validation and serialization.

  • Split correction config into Setup / Sweep / Output – replaced the monolithic CorrectionConfig god-object with three focused models: GeolocationSetup (durable, mission-specific setup built once), Sweep (the lightweight parameter experiment varied between runs), and OutputConfig. Added Sweep.with_strategy() / Sweep.update_param() for cheap, eagerly re-validated copies. Calibration collapsed to direct file paths (CalibrationFiles.los_vectors_file / psf_file). JSON loading is now load_config_files() (returns (setup, sweep, output) from "setup" / "sweep" / optional "output" sections), plus load_setup_from_json() / load_sweep_from_json(); load_config_from_json() was removed.

  • Standalone verification workflow – new verify() entry point and result models (VerificationResult, GCPError) for checking geolocation performance without running a full correction sweep.

  • GCP chip regridding support – new tooling to load HDF GCP chips, convert ECEF coordinates to geodetic coordinates, and regrid them to regular lat/lon grids; includes CLI examples for batch workflows.

  • Expanded correction workflow API – clearer public entry points (run_correction, run_image_matching, compute_error_stats) and structured result types (CorrectionResult, ParameterSetResult).

  • Deterministic parameter search strategies – support for random sampling, grid search, and single-parameter sweep via the SearchStrategy enum.

  • Improved image/data I/O – unified path resolution with optional S3 support; format-agnostic helpers for MATLAB, NetCDF, HDF, and GeoTIFF workflows.

  • Expanded documentation and examples – new correction user guide, regridding documentation, runnable examples, and JSON config templates.

Breaking Changes

  • curryer.correction has been significantly reorganized internally; loader protocols were removed.

  • Configuration now uses Pydantic models; some module, class, and function names were renamed or relocated.

  • Removed the monolithic CorrectionConfig (and load_config_from_json) in favor of GeolocationSetup / Sweep / OutputConfig and load_config_files / load_setup_from_json / load_sweep_from_json. Entry points now take setup first: run_correction(setup, sweep, inputs, work_dir) and verify(setup, ...).

  • This release should be treated as a breaking redesign, however there are minimal downstream users of correction.

Version 0.3.3 (2026-06)

  • Added the curryer.compute.geometry module: GeometryData computes geolocation/geometry ancillary fields (subsatellite and subsolar points, satellite radius, Earth-Sun distance, spacecraft position and geodetic altitude) through a selective-compute registry that queries each SPICE input once, with importable math-only leaf functions and a documented per-field NaN fill contract

  • Added frame-to-frame rotation primitives to curryer.compute.spatial: frame_to_frame_rotation, frame_to_frame_euler, and frame_to_frame_quaternion

Version 0.3.2 (2026-04)

  • Pinned SpiceyPy below 8.1.0 for compatibility

  • Refreshed the documentation

Version 0.3.1 (2026-02)

  • Added a citation file

Version 0.3.0

  • Add automatic SPICE file path shortening tools

  • Corrected a bug within the apply_offsets function of Correction loop

  • BREAKING CHANGE: Renamed MonteCarlo function to more generic “Correction”

Version 0.2.1 (2025-12)

  • Added support for custom pointing vectors in compute.spatial.compute_ellipsoid_intersection

  • Clarified function and parameter naming and improved testing for associated functions

  • Left deprecated spatial compute functions in place for backward compatibility with warnings

    • Both pixel_vectors and instrument_intersect_ellipsoid were deprecated

  • Bug fix for montecarlo testing using pytest tmp_path

Version 1.0.0 (unreleased)

  • Add documentation building framework with Sphinx
