What's New in version 3.9.4 Build 27423 Dev
  • This is a test release. Please post a note if you encounter any new or old bugs! And please back up your JMRI files before installing this, in case you want to go back to an earlier version.
  • This is the next in a series of test versions. We expect this series to end in a JMRI 3.10 production release around the end of 2014.
  • Some of the changes involved are quite extensive. They may require a certain amount of experience before they are working well. Therefore, this test version should be considered experimental.
  • JMRI is now only available under the GNU General Public License. For more information, please see our copyright and licensing page.
