April 11th, 2007: McStas webserver downtime

Unfortunately, the McStas web server was offline most of the day. We hope that the problem has now been sorted out. Should this not be the case, you are welcome to use our mirror site available at Sorry for any inconvenience the downtime may have caused you.

March 7th, 2007: NeXus/DANSE/MacOS X support in McStas 1.11

The McStas team went to visit SNS, and took the opportunity to implement the NeXus support in collaboration with SNS staff. This will be in the 1.11 release coming out very soon. Work was also carried out to ease import of McStas within the DANSE project. A MacOS X installation procedure will also be in the 1.11 (experimental). Full PGPLOT support will probably be included in the Windows installer as well.
