All notable changes to this project are documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[3.0.2] - 2026-01-10#

Fixed#

  • NXsource: check of input values for source type, and probe.

  • NXsample: fix setting of transformations.

3.0.1 - 2025-11-25#

Fixed#

  • Replaced pint.UnitRegistry() by pint.get_application_registry().

    • Impact: Reduces initialization time and improves performance.

3.0.0 - 2025-11-21#

Added#

  • Persist the NeXus coordinate system used by the application and expose it through the new nxtomo.geometry.CoordinateSystem enum.

  • Introduce DetXFlipTransformation and update detector flip helpers to reflect the McStas axis convention.

Changed#

  • Minimum supported Python version is now 3.10.

  • Centralize pint quantity consistency checks when merging detectors, warning (or failing) on unit mismatches and inconsistent magnitudes.

  • NXtomo.concatenate now skips missing components safely and restores parent links only when applicable, avoiding crashes for partial entries.

  • Continuous integration and documentation were refreshed, including updated guidance on the ESRF coordinate system.

Removed#

  • Drop the deprecated node_name constructor argument and NXtomo.concatenate parameter, along with legacy path shims.

  • Remove the deprecated UDDetTransformation and LRDetTransformation classes in favour of explicit flip transformations.

Fixed#

  • Correct axis swaps introduced by the McStas migration so detector flips are read and written with the expected orientation.

  • Ensure pixel size comparisons and detector distance merges handle pint quantities consistently when combining detectors.

  • Improve robustness to Virtual Source (VS) selection (when a VDS contains VS with partial dataset associated).

  • Saving rotation angle: make sure rotation angle are saved in degree

2.0.1 - 2025-07-16#

Fixed#

  • Restore backward compatibility for gravity transformations saved with an m/s2 unit string.

  • Reattach the detector parent after loading so saving an existing file preserves the original hierarchy.

2.0.0 - 2025-07-03#

Added#

  • NXsample propagation_distance, x_pixel_size, and y_pixel_size fields.

  • NXsource distance field.

  • NXdetector sequence_number field.

Changed#

  • Minimum supported Python version is now 3.9.

  • Unit handling migrated to Pint.

1.4.0 - 2025-04-03#

Changed#

  • Rename NXtomoDetectorDataSplitter to NXtomoSplitter.

  • Drop the NumPy < 2.0 restriction.

Removed#

  • Deprecated base_tilt and rocking attributes.

  • Legacy setup.py.

1.3.0 - 2024-11-29#

Changed#

  • NXtomoDetectorDataSplitter.split now prefers tomo_n over nb_part (!53).

1.2.0 - 2024-01-24#

Added#

  • Split the tutorial into dedicated guides for editing datasets and creating them from scratch.

Changed#

  • Support silx 2.0 and adopt the PyData Sphinx theme.

1.1.0 - 2023-09-27#

Deprecated#

  • NXtomo constructor node_name parameter (calls now ignore it when provided).

Changed#

  • NXtomo.save requires the data_path argument.

1.0.0 - 2023-08-07#

Added#

  • Initial release featuring the NXtomo application definition, NeXus object helpers (NXdetector, NXinstrument, NXmonitor, NXsample, NXsource, NXtransformations), and path utilities for tomography datasets.
