Our most recent release of Mantid, v3.10.0, required an update due to some changes in SNS DAS. We have put together a patch release to address these issues and we are pleased to announce that this is now available.
Installation packages can be found at http://download.mantidproject.org and the details of what is contained in the patch can be found at http://docs.mantidproject.org/v3.10.1/release/v3.10.1/index.html
