Release Notes for JMRI 4.1.6 release

Date: Dec 12, 2015

From: Matthew Harris

Subject: Test version 4.1.6 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 the next JMRI production release around the end of 2015. (See the tentative release schedule)

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.

Known problems with this release

The Digitrax PR2 does not work with this release. If you need to work with a PR2, please stay with JMRI 4.1.3 or earlier, or wait for JMRI 4.3.1 which should appear in December 2015.

DCC++ Support is broken in 4.1.6 (and 4.2.0). Sorry! If you need DCC++ support, please revert to 4.1.5 or wait for 4.3.1

Older warnings

See the JMRI 4.0 release note for warnings predating the 4.1 development series.

We are now building releases, including this one, from our GitHub repository. For more information on this, please see our documentation page.

The configuration is now stored in multiple files within a directory named profile inside a Configuration Profile instead of within the file ProfileConfig.xml. PanelPro and DecoderPro both should migrate from the old configuration to the new configuration seamlessly. See JMRI Issue #69 for more details. Please report any issues at our GitHub project.

The XML schema for decoder files has been made more precise. This shouldn't effect people who just use the JMRI decoder definitions as distributed, because they all work with this more precise version. But if you have decoder definitions of your own, you may have to update them. Ask for help on JMRI Users if you have trouble. Specifically, the decoder file verification will now reject a few things that it didn't catch before, even though they didn't really work:

As a side effect of checking this, the qualifier elements inside a variable now have to be at the front of the contents, and the label, comment and tooltip elements have to be at the back. You can't just sprinkle them around and hope the code finds them (because sometimes in the past the program would miss one; now we require an order we're sure the code will understand).

The code for handling Panel Editor / Control Panel Editor icons has changed to better deal with rotating icons. This has changed how opaque vs transparent icon backgrounds are handled. Please check your panels to make sure we haven't inadvertently caused a problem, particularly if you've got rotated icons and/or use have custom icons with transparent backgrounds. If there are any problems, please send in a copy of your panel file so we can recreate the problem and fix it.

Mac OS X 10.11 El Capitan requires signed drivers for USB adapters. If you've upgraded from an earlier version, your drivers may not work. That will cause JMRI to throw errors when it doesn't find communications links. To fix this, go to the web site for your adapter manufacturer, find the drivers that are listed to work with Mac OS X 10.9 or later, download, and install, then retry JMRI again.

RFID readers using the Olimex protocol were incorrectly decoding tag values - this has now been fixed. If you were using Olimex RFID readers with earlier versions, your existing ID Tag database will contain invalid tags. New ID Tag entries will be generated for each correctly read tag - this will require that any additional information be re-entered and, optionally, old invalid entries manually deleted.

Jython has been upgraded to version 2.7.0 with the following potentially breaking changes:

Decoder definitions that use the "ivariable" form are now deprecated. Definitions included with this release have been converted to the new form. If you have decoder definitions with the older "ivariable" form, they will no longer validate, but can still be used for the first couple of test releases in this series. Please ask on the JMRI Users group for help converting them, or just drop them and use the current definitions.

The OpenLCB 0.6.4 library in this version has a bug in its alias calculations which prevents JMRI from communicating occasionally. A patch has been submitted to the OpenLCB group. In the meantime, the workaround is to restart JMRI and/or the node and try again; that might allocate different alias values.
