Release Notes for JMRI 4.7.4 release

Date: May 28, 2017

From: Bob Jacobsen

Subject: Test Release 4.7.4 of JMRI/DecoderPro is available for download.


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 releases. We expect this series to end in the next JMRI production release around the middle of 2017. (See the tentative release schedule)

Some of the changes involved are quite extensive. They may require a certain amount of experience before they are working well. Therefore, this test release 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.

Known problems with this release

If any of those effect you, please either wait for JMRI 4.7.5, due out shortly after this one, or (once there's a fix for the problem) pick up a development build installer from Jenkins.
