Release Notes for JMRI 2.11.5 release

Date: May 28, 2011

From: Bob Jacobsen

Subject: Test version 2.11.5 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 fifth in a series of test versions. We expect this series to end in a JMRI 2.12 or 3.0 production release in 2011.

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.

Older warnings

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.

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.

Zimo sound decoders allow the end user to select the sounds played, and their volumes, from any of those stored on the decoder. As an example, this allows the user to change the horn, or brake noises, as well as set the sound levels for each element. This is done using a technique Zimo call "psuedo programming". An Ops-mode CV change to CV300 is made to enable pseudo programming, then function keys select various sounds. The throttle speed control acts as a volume control. Some function keys will end the programming (as will issuing a new Ops-Mode change of the CV). The difficulty for end-users in this approach is that the initial selection of which ops-mode value to select is not obvious, the throttle function keys when mapped to the pseudo programming features are not intuitively laid out (may be OK on a Zimo handset) and pressing some functions can have unexpected consequences (turns sounds off for that aspect of the decoder!).

The new "" script is an attempt to make Zimo Pseudo Programming a bit easier for the end user. It can be seen as complimenting my earlier CV61 Zimo function mapping tool. (And perhaps one day, I will bring them together into a general Zimo programming aid tool !).

Its been tested by a couple of Zimo sound users, and we found a bug in the Zimo decoder firmware which resulted in one feature being temporarily removed from the script pending a decoder update from Zimo.

Randall Wood updated the fast clock support so that it maintains a memory variable IMRATEFACTOR with the rate information.

Giorgio Terdina fixed a problem with the XnTCP adapter code.
