Release Notes for JMRI 2.11.4 release

Date: April 16, 2011

From: Bob Jacobsen

Subject: Test version 2.11.4 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 fourth in a series of test versions. We expect this series to end in a JMRI 2.12 or 3.0 production release in 2011.

It contains many new features, including:

along with other changes. See the complete list below.

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:

Development Version 2.11.4 contains significant improvements to the Powerline Interfaces. Some of these improvements involved a complete restructuring of the underlying code. As a result, previously working Preferences may now show no connections for some of the Powerline Interfaces. If this occurs, go to Preferences and setup the Powerline Layout Connections again. Then save the Preferences and restart JMRI.

Older warnings

In Development Version 2.11.3 JMRI instituted a more robust and transparent system for handling missing panel icon files. If missing icon files are discovered during the panel loading process this system presents a dialog box that allows the user to either delete the offending reference or use the file browser to find the proper location. Older versions of JMRI didn't always fully remove the references to deleted panel icons. Panels which contain these stray references will present the dialog box during the first panel load. If the panel worked fine before, simply choose the delete option for each "missing" icon presented to remove the stray references. Once the panel has finished loading, save/store the panel file, quit JMRI and then reload. As a precaution, we recommend either making a backup copy of your panel file before diving in or saving the modified file under a different name

There have been extensive changes to the throttle code. If you have written scripts that use throttles, particularly multiple throttles, please check to make sure they still work.

The numerical values of "ON" and "OFF" for Lights changed in JMRI 2.11.2, along with some of the other constants in the class. This will have no impact on people just using the program. If you're using scripts with numerical values in them, please recode them to use the symbolic values.

Known problems with this release

None at the time of this release.

Matthew Harris:

Pete Cressman:

Lionel Jeanson:

Kevin Dickerson:

Nigel Cliffe:

Jack Shall added the EMD 710G3C-T2 and GE Gevo-12 to the Tsunami decoder definitions.

Marc Fournier improved the wording in the reset section of the BLI Paragon decoder definitions.

Michael Greene updated the Lenz Ultradrive decoder definition.

Stephen Lowens provided an updated Digitrax SFX decoder definition that includes the most recent decoder definition coding techniques. The file includes definition for new decoders: SDN144PS, SDN144K0A, SDN144K1E, SDH164D & SDH164K1A, B & C, as well as legacy decoders SDH104K1A, B & C and SDH104T1. T he definition includes new CVs 60, 133, 134 & 154 and adds default values for all CVs where documented. He also compared the documented defaults with an actual decoder and corrected errors where Digitrax documentation is incorrect.

Alain Carasso add the latest version of Roco 10745 decoder, more sophisticated than Lokpilot Basic, but less than full Lokpilot one, and also a 10745 Roco decoder file (no long address settings).

Updated the NMRA manufacturer code list with values to March 8, 2011.

Giorgio Terdina released a new version of AutoDispatcher, supporting user-defined track colors and including new schedule commands to test the held state of signal heads and to operate turnouts and accessories like level crossings.
