Larch version 0.9.59 has been released.  It should now be installed by default using all installation mechanisms, and you may see a notice to update if running xas_viewer.

This is mostly bug fixes, but some are important enough to warrant pushing out now.  Changes are detailed at https://github.com/xraypy/xraylarch/releases/tag/0.9.59

For XAS Viewer use, the most important of these are 

 a)  "energy reference" and "energy shifting" of spectra work much better.

 b) the action of the "pin icon to select points on the graph" has now changed (by popular opinion) to be: click on pin icon, *and then* cliick on point of the graph.  

There are also new binary installers - the one for Linux might work for more people ;), and the installation might be faster for more people.

We're hoping that there will be another release in a couple of months to give a more comprehensive "Project File" concept.   But, as always, suggestions or comments are welcome.
