We always offer the latest Squeezebox Server version for download in the Max2Play interface when we have tested it extensively and can be sure that the most important Max2Play or Squeezbox features work smoothly. Accordingly, I would recommend that you only use the installations we offer, as long as you do not miss any features or bug fixes that the new version of LMS provides. In this case you can install the new version via ssh if you want. However, we cannot guarantee that the installation will work without errors.
We will test the new server version as soon as possible and offer it for download.
