Version history

Current GitHub code (modified 9 Jun 2026):
2026.6.0 (18 Jun 2026):

  • Add MCR-ALS to data combinations, including docs and an example.

  • Split PCA into PCA-classic and PCA-cumulative.

  • Adapt to new Python Qt bindings.

  • Improved interaction with the file system, particularly when using filters.

2026.4.0 (17 Apr 2026):

  • Add slices to data conversion.

  • Add pinhole correction to LCF of transmission XAS.

2026.3.0 (5 Mar 2026):

  • Add cumulative logging to time profiling that sums the execution times of each method over all data items.

  • Add name change and color change of the splitter button ‘corrections’ that signals a used correction, which is useful because this splitter is most frequently collapsed.

  • Add optional vertical separation between curves in 1D plots.

  • Fix a bug of triggering transformations after a GUI update from data.

2026.1.0 (5 Jan 2026):

  • Add a pipeline-specific “How-tos” tab to the main tabified dock widget.

2025.11.0 (5 Nov 2025):

  • Bug fixes.

2025.10.0 (30 Oct 2025):

  • The functionality and look of ParSeq on macOS have been revised. Check boxes and radio buttons did not work. Tab widgets were of a small size and with a too dark background. Table headers and tree view headers were too small. All the above issues have been fixed.

  • The Save project dialog now sets its check boxes from the ini file.

  • Minor bug fixes and updates.

2025.8.0 (31 Aug 2025):

  • Add workaround for corrupt h5 files: stop using h5Model.insertFileAsync().

  • Minor bug fixes.

2025.3.1 (28 Mar 2025):

  • Bug fixes in doc builds.

  • Improve tie expressions in LCF.

2025.3.0 (13 Mar 2025):

  • Enable custom node icons.

  • Enable node arrays with an extra abscissa.

  • Add glitch detection.

  • Add metavariables to fits.

  • Enable several transformation widgets per node, with the idea to get a widget in the ‘corrections’ splitter.

  • Add optional interpolation when making data combinations.

  • Add Principal Component Analysis and Target Transformation to data combinations.

  • Minor new features and minor bug fixes.

2024.11.0 (23 Nov 2024):

  • Finalize general data corrections. Include doc pages with descriptions and animated examples. Add “delete spikes” data correction.

2024.5.0 (4 May 2024):

  • Add general data corrections.

  • Add EXAFS fit. It features two fit intervals (k and r), constraints, ties to other parameters (also of another data item) and error analysis.

  • Update the main help pages.

2023.5.0 (May 2023):

  • Add curve fitting facilities. Implemented 2 general fitting routines: linear combination fit and function fit.

1.0.0 (4 Apr 2023):

  • Functional ParSeq and a few pipelines.
