+========================
+version 6.5, 20/2/2020
+========================
+As of version 6.5, SIMRES source code is distributed via GitHub. 
+With the move to git repositories, the structure of the binary and source 
+packages has changed significantly. The functionality remains the same 
+as for version 6.4. 
+A new PGPLOT graphics driver for Windows (similar to pgxwin_server on Linux) 
+has been developed and added as a submodule to SIMRES. 
+The user interface (written in Java) is now also added as a submodule and includes Ant
+builder scripts. 
+The SIMRES core can now be compiled using the GNU gcc/gfortran suite (using the
+mingw-w64 tools on Windows)
+
+=======================
+version 6.4, 6/9/2019
+=======================
+- Improved MCPL functionality (import/export neutrons)
+- Binding with McStas using MCPL (see doc/simres-guide.pdf)
+- Export of sample scattering events (see demo/STRESSPEC)
+- New demo examples (choose demo on startup)
+- New sets of supermirror lookup tables for various models
+- Simulation of guide misalignment
+- Improved guide waviness model
+- Hollow sample shapes (set wall thickness parameter)
+- Improved stability and monitoring of the simulation kernel
+- 64 bit binaries
+
+===============
+version 6.3.5
+===============
+- New sources: ESS butterfly, ISIS
+- Export to MCPL file (use command MCPL)
+- Choice of gonio-stage order for component positioning
+- Recording of events in guides: m-value, escape coating, escape
+
+===============
+version 6.3
+===============
+- updated user guide (PDF)
+- console command - running simulations on a remote server
+- new source definitions for ESS baseline 2013 and pancake moderators
+- SGUIDE: manual (free shape) or automatic (elliptic, parabolic) shape setting 
+- new bug fixes (see simres-relaese-notes.pdf)
+
+===============
+version 6.2
+===============
+- new user guide (PDF)
+- console command - running simulations on a remote server
+- new source definitions for ESS baseline 2013 and pancake moderators
