<p class="MsoNormal"><span style="mso-fareast-language:EN-US"> - Windows and macOS packages are now named MantidWorkbench-6.4.0 with the appropriate extension. Other than this they are used in the same manner.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"> - A new linux tarball ,``mantidworkbench-6.4.0.tar.xz``, now supports many Linux distributions and should work on any 2010+ distribution. This can simply be unpacked with `tar xJf mantidworkbench-6.4.0.tar.xz

extracted and run anywhere, so does not require root permissions to install.</span><o:p></o:p></p>
