• fix many Numpy uses that have been deprecated in Numpy2.
• require Numpy<2, at least until other packages (pymatgen, scikit-image) support it.
• drop requirement for peakutils, add function to reproduce peakutils.peak_indices
• improve debugtime utility, use tabulate module for output.
• add support for Python 3.12, and drop testing of Python 3.8.

• Feffit Panel: fixes for handling cases with no data, to allow EXAFS simulations without data.
• Feffit Panel: fix plotting individual paths (#515).
• PCA Panel: fix plotting of group with model and other plot variations (#520).

• Analysis Panels can be selected or deselected from the Preferences Menu.
• remove "XY data" (was "raw data") from XAS Normalization Panel
• reading general "XY data" (was "raw data") into separate Panel
• "Spin Arrows" to in/decrement numbers are now acceptably sized on Linux/Gtk3.

  can be used in Path Parameter expressions: 'nleg', 'degen', 'rmass',
  'rnorman', 'gam_ch', 'rs_int', 'vint', 'vmu', 'vfermi'.

• Larix/Background Subtraction: better getting of rbkg (and ek0) from data
  group, not default value (say, 1.0 for rbkg) (GH
• Larix/Dialogs: fix bug in smoothing dialog, and better preserving of "zoomed view" for several data-processing dialogs.
• More fixes to Struct2XAS codes.

0.9.72

A few new features, and several bug fixes and improvements:

[Added or changed features]

• XAS Viewer (a naming demonstrating that Matt is poor at naming things) has been renamed "Larix".
• Structure information (from CIFs or data from the Materials Project) can now be converted to inputs for FDMNES. (PR #458). See the Jupyter Notebook example at https://github.com/xraypy/xraylarch/blob/master/examples/Jupyter/struct2xas_examples.ipynb. This should be viewed as ongoing work, but real progress has been made here, thanks to @beatrizfoschi @maurov @Ameyanagi @mretegan
• Binary Installers have been updated for all platforms, and are now based on Python 3.11.5.
• Significant improvements to Larch_XRD1D to read calibration files, integrate XRD images, display 1D XRD patterns, save XY outputs, and compare XRD patterns to crystal structures from the AMCSD database.
• Improvements in handling Bliss data, especially from ESRF BM16.
• Some improvements in Plotly plotting.
• Several cleanups and purging of the legacy _larch argument for many python functions.
• Some cleanups of XRF fitting results and generating XRF fitting scripts.
• Feffit reports now use floating-point formatting with strings of length 10 (was 11, led to many 1-digit diffs in outputs).

[Bug Fixes, Code improvements]

• fix for setting e0 with very badly formatted data.
• layout tweaks for Larix/XAS Viewer, especially for Linux/Gtk3.
• better checking of formula parsing for CIF formulas
• more gracefully closing AMCSD sqlite, avoiding crashes.
• more fixes to energy calibration.
• better defaults for normalization parameters when reading in data.
• several fixes in reading and working with Session Files and saved Feff calculations and Feffit results.
• better detection of non-default values for kstep in EXAFS routines.
• more uniform use of a single mkdir function.

0.9.71

Mostly bug fixes, mostly for XAS Viewer:

• reading data and finding E0 for data with repeated or even "almost repeated" energy points
• more improvements to finding "small energy step" value when finding E0.
• fix reading of XAS in degrees.
• update to supported usage of polynomial fitting with numpy
• fix remembering of energy ranges for LinCombo and other XANES processing panels.
• E0 is now separate for XANES / Normalization ('.e0') and for EXAFS extraction ('.ek0'), defaulting to the same value.
• Groups can now be iterated over!

Several other smaller bugfixes!

0.9.70

Improvements to XAS Viewer:

• bugfix for deglitching
• better energy calibration dialog, and several bugfixes associated with energy alignment and setting of energy references
• update dependency requirements for pyshortcuts and wxutils
• Add "Larch Updater" application/shortcut to better run automated updates.

• Add "flat+normalized" and "normalized+i0" plots, with small tweaks to flattening.
• improvements (more needed) to CIF database and reading with sqlalchemy2.
• importing data from text files and Specfiles now supports reading multiple columns into individual groups. Currently, these multiple-columns must use a shared "normalization / I0" array and will not use a logarithm: suitable for data columns that are fluorescence/emission or already mu(E) data.
• summing of channels with ICR/ORC channels and some other ways of expressing deadtime information can now be done when reading in text data files.
• the result of a Linear Combination Fit can now be inserted as a Group in the File list.
