This is to inform you all that the next stable McStas release 2.6 will become available during January 2020.
- If you have any useful contributions to make, in the shape of instruments or components, now would be a good time. :-)
I would also like to mention that we aim to make an official beta-release of our experimental McStas 3.0 available soon. This will happen following v. 2.6 within the first months of the new year, and be the first release to support running simulations on Nvidia GPU processors. Probably not all of our components will be ported at release, but most of what you do on CPUs today will be available!
A short set of slides is available here outlining what is coming, when we started and how we achieved it... :-)
Seasons greetings on behalf of the McStas team,
Since the problem seems to occur consistently on updated Mojave (10.14) and Catalina (10.15) systems, a patched version of our macOS App bundle has been uploaded to our download page.
Please let us know via the mailinglist or by creating a GitHub ticket if any further issues arise.
Did you ever wonder how the number of included components and instrument files in McStas changed over time? - And did you know that we now include 215 components and 192 example instruments?

With the latest update to Xcode command line tools on macOS, there is no longer an option to install the system header files to the legacy location of /usr/include .
This unfortunately means that the miniconda-based gcc that we distribute with McStas (and set up by default) is no longer able to locate the math.h header file and compilations fail with
mccode-r.h:39:18: fatal error: math.h: No such file or directory
Our suggested workaround is to configure your McStas installation to instead use the system-provided clang compiler, see our GitHub issue #799 for a detailed description of how to do this.

In collaboration with the China Spallation Neutron Source, the McStas team participated in the first ever McStas school in China in the last week of March.
All lecture material and exercises are available through our new McStas school site, hosted on GitHub
Further, our hosts suggested we recorded videos of the lectures which are slowly becoming available on the new McStas youtube channel.
The results from the 2018 McStas user survey are now online at http://survey2018.mcstas.org.
The main conclusions are that
