Changelog

Changelog entries for the development version are available at https://exspy.readthedocs.io/en/latest/changes.html

0.3 (2024-10-11)

New features

• Support for Dirac GOS in the gosh format for EELS quantification, which includes the relativistic effects (e.g. spin-orbit coupling) based on Dirac equation. (#72)

Enhancements

• Make numexpr an optional dependency to allow installation in pyodide. (#80)

• Mention source of elements database in docstring (#87)

Bug Fixes

• Add back functionalities, which were unintentionally removed from public API when splitting from hyperspy in exspy.utils.eds, exspy.utils.eels and exspy.material. (#59)

• exspy.models.EDSModel.fit_background() fixes:

  • fix error when using linear fitting,

  • fix resetting signal range after fitting background,

  • suspend plot when fitting background. (#76)

• Plot background and integration windows fixes and improvements:

  • fix plotting windows with navigation dimension >=2,

  • raise improved error message when windows are out of the range of the signal, (#86)

Improved Documentation

• Fix examples in user guide, which needed to be updated after the split from hyperspy. (#59)

0.2.1 (2024-07-12)

Bug Fixes

• Fix gradients of the EELSArctan component. (#55)

• Fix blocked eelsdb queries (#66)

Improved Documentation

• Fix broken links in the documentation and missing docstring of the PESCoreLineShape component in the API reference. (#55)

0.2 (2024-04-10)

Bug Fixes

• Fix restoring Gosh and Hartree Slater GOS from stored models. (#32)

Improved Documentation

• Add eXSpy logo and adapt spelling to capital X (#22)

• Fix DOI and add more badges to readme file. (#36, #38)

Maintenance

• Use ruff for linting and formatting the code. Remove redundant GitHub workflow in favour of pre-commit. (#27)

• Fix deprecation scipy and numpy warnings. (#33)

0.1 (2023-12-03)

New features

• Support for tabulated Generalised Oscillator Strengths (GOS) using the GOSH open file format. By default, a freely usable dataset is downloaded from doi:10.5281/zenodo.7645765 (HyperSpy #3082)

• Add functionality to fit the EELS fine structure using components, e.g. hyperspy.api.model.components1D.Gaussian. (HyperSpy #3206)

Enhancements

• Enable signal_range arguments when using subpixel=True in align_zero_loss_peak() (#7)

Maintenance

• Use towncrier to manage release notes and improve setting dev version (#14)

• Use reusable workflow from the hyperspy organisation for the doc workflow (#13)

• Consolidate packaging metadata in pyproject.toml. (#4, #10)

• Use setuptools_scm to set holospy version at build time (#10)

• Add package and test workflow (#10)

• Add python 3.12 (#10)

• Add release workflow (#10)

Initiation (2023-10-28)

• eXSpy was split out of the HyperSpy repository on Oct. 28, 2023. The X-ray energy dispersive spectroscopy (EDS) and energy electron loss spectroscopy (EELS) functionalities so far developed in HyperSpy were moved to the eXSpy repository.
