## Release 3.5, 5th October 2015

We are proud to announce version 3.5 of Mantid, this version includes significant improvements to multidimensional visualisation, the addition of an "Region of Interest" Mode into the Instrument view and a new multiple scattering absorption correction algorithm based on the work of Jerry Mayers. In addition to this we are also releasing the [Mantid Forum](http://forum.mantidproject.org/) to provide a center for support and conversation across the Mantid community.

These are just a few headline points for the changes in this release, so please take a look at the release notes, which are filled with important changes and improvements in many areas. The development team has put a great effort into making all of these improvements within Mantid, and we would like to thank all of our beta testers for their time and effort helping us to make this another reliable version of Mantid.

Throughout the Mantid project we put a lot of effort into ensuring Mantid is a robust and reliable product. Thank you to everyone that has reported any issues to us. Please keep on reporting any problems you have, or crashes that occur to mantid-help@mantidproject.org or use our contact page.
