Release Notes for JMRI 4.7.3 release

Date: April 17, 2017

From: Bob Jacobsen

Subject: Test Release 4.7.3 of JMRI/DecoderPro is available for download.

Notes:

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 releases. We expect this series to end in the next JMRI production release around the middle of 2017. (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 release 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

New warnings for this release:

Older warnings

See the JMRI 4.6 release note for warnings predating the 4.6 development series. These may be relevant to you if you're updating from an earlier version.

(Since JMRI 4.7.1) JMRI no longer supports the portable paths resource: or file: that were deprecated in JMRI 2.13. When loading a panel, an error message will be displayed if the panel contains a path that starts with resource: and the panel will not load until changed using an external editor. Paths starting with file: cannot be automatically flagged because JMRI allows file: URLs.

(Since JMRI 4.7.1) JMRI applications will not load a panel file that fails XML validation; an error will be shown that should explains the error, allowing it to be fixed using an editor. (The explanations remain a work in progress.)

(Since JMRI 4.7.1) The LocoNet Server (the LocoNetRMI service; not the LocoNetOverTcp service) in this version of JMRI doesn't properly interoperate with JRMI 4.6 or before. The workaround is to update both client and server JMRI machines to the same JMRI version. We expect this will be fixed in JMRI 4.7.5.

(Since JMRI 4.5.6) As part of fixing the TMCC throttle issue, the handling of TMCC preferences was changed. If you have a TMCC connection configured, please go to the "Defaults" pane in the Preferences window and make sure that the TMCC connection is selected for the appropriate device types.

(Since JMRI 4.5.2)This and future releases of JMRI may not function on OS X if the Java SE 6 provided by Apple is installed. OS X operating system updates routinely remove this version of Java SE 6. Please raise any issues concerning this on the user's group.

To remove Java SE 6 from OS X, follow these steps (these steps assume JMRI is installed in the folder /Applications/JMRI, if not, adjust the following paths as needed):

  1. Open Terminal.app.

    El Capitan only: Reboot into Recovery Mode by restarting your Mac and pressing Cmd-R until the Apple logo appears. Once in Recovery Mode, select Terminal from the Utilities menu.

  2. Run the command /Applications/JMRI/PanelPro.app/Contents/Resources/uninstall-java6.sh It can take up to a half hour to complete. Wait for the message Removed Apple Java SE6.

    El Capitan only: Run the command bash /Volumes/Macintosh\ HD/Applications/JMRI/PanelPro.app/Contents/Resources/uninstall-java6.sh /Volumes/Macintosh\ HD It can take up to a half hour to complete. Wait for the message Removed Apple Java SE6.

  3. El Capitan only: Restart your Mac.

(Since JMRI 4.5.2)Support for directly executing AppleScript within JMRI has been removed due to changes in macOS and Java outside our control. If you require the ability to use AppleScript, you may be able to add this capability on your own by visiting JMRI AppleScript Support, but please be aware that this may not work on upcoming releases of macOS or Java.

(Since JMRI 4.5.1)Internal turnouts and sensors need to have complete, individual system names. The names "IT" and "IS" (without any suffix) are no longer permitted: "IT12" is fine, but just "IT" is not. Most panel files that contain these should automatically migrate them to new names when saved, but in some cases you might need to manually update them.

(Since JMRI 4.3.3) You can now set the order of your startup items: If you're opening panel files, running scripts, etc as the program starts up, there's a preferences pane that lets you easily set the order in which those happen. If you've set the order manually (e.g. by editing configuration files) in the past, please check this preference to make sure it's set the way you want.

(Since JMRI 4.1.2) Jython has been upgraded to version 2.7.0 with the following potentially breaking changes:

(Since JMRI 4.1.1) 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.

Download links:

Please note that the download links in this and future JMRI releases link to Github servers. If that doesn't work for you, the files up to 4.11.x are also still available from the SourceForge.net servers. Please let us know of any problems.

Changes since production release 4.7.2:

The list of included commits is available from our GitHub code repository.

DecoderPro

DecoderPro now has two additional options for how it handles CV reads and writes. These are set via the Programmer section of the Roster preferences panel.

These options are stored with the preferences for future use. A new DecoderPro Roster window will pick up new values of the options, without having to close and restart the program.

Hardware Support

Programming capability facades are little tools that are used to handle things like indexed CVs, special ways to write upper-address CVs not supported by a command station, etc. Previously, these would have trouble recovering when they encountered multiple errors. (This came up in the context of the time that the DCS240 command station takes to do writes, which JMRI thought was an error) This has now been greatly improved.
