Release Notes for JMRI 3.9.6 release

Date: December 7, 2014

From: Bob Jacobsen

Subject: Test version 3.9.6 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 one of the last in a series of test versions. We expect this series to end in a JMRI 3.10 production release around the end of 2014.

JMRI is now only available under the GNU General Public License. For more information, please see our copyright and licensing page.

The JMRI 3.9.* releases series, including this one, and JMRI 3.10 (expected in December 2014), will be the last JMRI releases that will work with Java 1.6. To use any later JMRI test or production releases, you'll have to update the Java on your computer to Java 1.8 or later. All JMRI releases 3.9.3 and are tested on Java 1.8, so you can do the Java update now if you want to.

The 3.9.5 release had some changes to XML file processing. They're meant to be transparent for existing files (roster, panels, etc), but mistakes happen. If you encounter trouble with existing roster or panel files, please let us know. Most importantly, if that happens, immediately make a back up copy of your files!

RFID support has been changed to allow for additional protocols - existing CORE-ID readers should remain unaffected but, in certain circumstances, it may be necessary to update connection configuration with the correct protocol.

The activation.jar library is no longer included with the JMRI download. This shouldn't have any impact on you, but it's remotely possible that it might impact you if you have your own Java code that you're combining with JMRI and/or you're still using a Java version before Java 1.6. (Scripts and panel files will not be impacted.)

Images associated with roster entries are now saved to the roster directory instead of the resources directory when added to the roster entry. Existing images are not moved.

The XmlIO web service has been deprecated and is scheduled to be removed after JMRI 3.12 (July 2015). All users and developers who are relying on direct access to the XmlIO API are recommended to begin using the JSON API. inControl web throttle users are recommended to begin using webThrottle instead, or to plan on investing in devices that can support webThrottle, WiThrottle for iOS, or Engine Driver for Android.

Several methods in the InstanceManager class have been deprecated and will be removed after JMRI 3.12 (July 2015). This doesn't affect JMRI users, but if you have your own code that uses JMRI, please take a look at the code and make any necessary changes.
