Release Notes for JMRI 3.1.6 release

Date: December 2, 2012

From: Bob Jacobsen

Subject: Test version 3.1.6 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 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:

To allow use of UTF-8 characters (special characters with accents, Japanese text, etc) in XML files, particularly decoder definitions, the default file encoding has been changed to UTF-8. This requires a change to the startup scripts distributed with JMRI. If you're just using the JMRI-provided startup tools, you should be all set. If you're using your own custom startup scripts, you need to add a "-Dfile.encoding=UTF-8" option to them. If you have any problems with special characters in your existing files, please let us know as soon as possible.

Older warnings

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