Dear Matthew, Thank you for the kind email! I always appreciate your hard work for the XAS community. I have a few small feedbacks: 1. In Help > Check for updates, it still shows 2024.12.0 as the newest version. 2. When I tried the pre-edge peak fitting for one of my data with a Voigt profile, it resulted in a negative value of Gamma, which should be unphysical (to my mind at least). It turns out that my pre-edge peak can be fitted very well to a single Gaussian. Is it an error that can be fixed? 3. In pre-edge peak fitting again, I tried first fitting the baseline, then fixing the parameters for baseline with what was fitted, then fitting the peak. Somehow, the resulting fit shows the same baseline parameters, but the plotted baseline is shifted downwards. For 2 & 3, I have attached screenshots as well as the raw data. If these are issues too minor/trivial, please feel free to ignore them. I would also like to ask if I may be added to the zoom meeting. By the way, I am on the west coast, so only after 11am your time will work for me. But if 9 am your time is the best for other reasons, it is ok. Perhaps being able to access the recording would be enough for me. Thank you very much!

Hi Folks,
Larch version 2025.1.1 has been released. This fixes a serious issue for generating Feff data files, and a few other issues too.
It had been more than a year since fresh binary installers were made, so those have been updated too.
As always, suggestions and feedback are welcome. Since this is the first release of the year, and since we have an XAFS Conference and Q2XAFS meeting coming up this summer in Chicago (July 14-20), I encourage people to think about what they would like to see for these and other tools for XAFS and related work. And also: think about coming to the conference ;).
For those interested, we’ll restart monthly meetings to discuss the development of these tools later this month (probably January 24, probably 9 AM Chicago time). This is not development-only, but often about feature requests, complaints about the GUIs, and ideas. If you are interested, let me know, and I’ll happily add you to the invite list for that Zoom call.
We would like to hear feedback on:
1. Should we have a monthly Zoom meeting (maybe alternating time of day) as “Office Hours” ? 2. Should we send a survey of user needs and desires for features, recommendations, etc?
If you have opinions on any of these topics, let me know either here or by direct email.
