Hi Folks, Larch 0.9.46 is now available, with installers for Windows, MacOS, and Linux at https://millenia.cars.aps.anl.gov/xraylarch/ It has been several months since I announced a release. For XAFS and XANES analysis, there have been several recent improvements: - add reading and visualizations tools for RIXS plane data (thanks, Mauro Rovezzi!). - better support for reading older Athena Project files. I think all Athena files are now supported, but if you run into trouble, please send me the file you are having problems with. - better support for reading and parsing data files from more XAFS beamlines, at least those in North America. If you have data files that are not being read correctly (or even "well", including figuring out how columns should be labeled), please send an example file and how you expect it to read. - several fixes to the XAS Viewer application. There is still a To-Do list for this, but if you have suggestions, problems, or irritations using this, please let me know. There have been steady improvements in using Larch as a Python library, especially from Jupyter consoles and Notebooks. Some improvement in the docs and examples have been made. These are still behind but will continue to be worked on over the next few months. If you having any questions or suggestions, please let us know. --Matt Newville
