Description

New features:

  • Calib2: improve "recalib" like calibration, without peak-picking but a known geometry in input (#2840)
  • Sensor: new CZT (Cadmium-Zinc-Telluride) detector material
  • Support for logarithmic/sqrt/non-linear units binning space with formula-based conversions
  • Multigeometry integration results now support union()

Bug Fixes & Code Quality:

  • New `ImmutableDict`` class for immutable dictionary representation
  • Fixed Integrate1dResult.rebin1d()`` to properly handle dummy` values and normalization
  • PoniFile Enhancements: calibrant and image metadata are now saved to ease Recalibration
  • Sensor Configuration now properly initializes material strings
  • Wavelength is checked in enable_parallax()
  • Several typos and grammar improvements in documentation/tutorials
  • Improved kernel OpenCL compilation for silx v3+ compatibility

Supports python 3.10-3.14, 3.14t is untested. 62 commits over 2 month
