Release Notes for JMRI 3.5.4 release

Date: October 12, 2013

From: Bob Jacobsen

Subject: Test version 3.5.4 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 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 3.5.3:

Dan Boudreau made the following changes to operations:

Oscar Moutinho added a new webThrottle app, based on JSON and web sockets

Steve Todd updated the web version of the Operations Manifest to work properly for in-route trains, and rearranged and added some items to the JMRI Web Server local home page.

Matthew Harris updated the MS Windows launcher to check for an already running instance of a JMRI application and to provide an option to continue or abort.

Fixed problem where black-on-black panel icons would not display properly.

Robin Becker improved the TAM quad decoder definition

Dave Heap improved the DecoderPro operation: Sheet Read and Write operations were ignoring readOnly and writeOnly attributes if the CV value was Unknown. The readOnly and writeOnly attributes are now always respected for all Sheet operations. Read Changes will still attempt to read Unknown values but Write Changes will not attempt to write Unknown values.

Dave Heap added extra CVs, panes, workarounds for programmer issues and numerous fixes/improvements for ESU V4 files.

Alain Carasso improved the Mistral Gold decoder definition with "Other Sound Setting" (CV62)

Dave Heap improved the TCS WOW decoder definition.

Steve Lowens improved the Tsunami Rapido F9A definition.

Jeff Schmaltz added a decoder definition for the SoundTrax Piko decoder
