Release Notes for JMRI 2.99.3 release

Date: Feb 20, 2012

From: Bob Jacobsen

Subject: Test version 2.99.3 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 3.0 production release, probably in Summer 2012.

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.
