Release Notes for JMRI 3.5.5 release

Date: November 17, 2013

From: Bob Jacobsen

Subject: Test version 3.5.5 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 next in a series of test versions. We expect this series to end in a JMRI 3.6 production release around the end of the year.

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.

Changes since test release 3.5.4:

Changes to decoder programming and definition allow specification of workarounds when a command station only handles a subset of CVs, and the decoder provides a way to access the full range locally. Useful with ESU and Zimo decoders, but not all (close to none) of the decoder definitions have been updated to use this.

NCE command station programmer updated to indicate when it can't access high-address CVs.

Dave Heap added automatic display of CV numbers in DecoderPro tooltips. To see the CV address for a decoder parameter, hover your mouse over it. By default this is off (DecoderPro exists to hide this information, not show it), but you can turn in on with a preference under Roster, then Programmer.

The OpenLCB lib was updated to the current version. This includes several memory-read protocol fixes.

Dan Boudreau made the following changes to operations:

Ken Cameron made the following changes:

David Zuhn updated the Mac OS X launcher to handle different Java configurations, particularly when installing a clean version of Mac OS X.

Bjorn Kvisli and Pierre Billon created multiple Doehler & Haass decoder definitions.

Bjorn Kvisli added decoder definitions for the Arnold N scale decoders.

Peter Ulvestad added a decoder definition for the MRC 1952, improved the definition for the MRC 1957, added the 1922 and 1916.

Suzie Tall fixed some cross-references that were preventing the CROR-2008 and InfraBel signals from displaying properly.

Dick Bronson provided additional UTCS track segment icons.

The timestamp on messages in the console output was changed to default to a real timestamp like "2013-11-17 15:16:07,486" in local time.
