Release Notes for JMRI 3.1.3 release

Date: September 11, 2012

From: Bob Jacobsen

Subject: Test version 3.1.3 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 versions. We expect this series to end in a JMRI 3.2 production release.

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.

New warnings for this version:


Older warnings

This release, and all other releases in this cycle, require Java 1.6.

Known problems with this release

This release does not work properly with some NCE systems. People have reported problems programming CVs and running trains. We expect that this will be fixed in JMRI 3.1.4 when it's released. In the meantime, we recommend that NCE users not install this release (JMRI 3.1.3), but stay with JMRI 3.1.2 instead.
