Release Notes for JMRI 4.5.8 release

Date:December 14, 2016

From: Bob Jacobsen

Subject: Test version 4.5.8 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 perhaps the last in a series of test versions that will end in the next JMRI production release in December 2016. (See the tentative release schedule) We would very much appreciate testing and feedback, so we can catch bugs before the production release.

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 version:

Older warnings

See the JMRI 4.4 release note for warnings predating the 4.4 development series. These may be relevant to you if you're updating from an earlier version.

(Since JMRI 4.5.6) When a Digitrax DCS240 is the command station, JMRI throttles may not be able to take control of a locomotive or consist in some cases if the DCS240 "expanded slots" (i.e. 400 slots) feature is in use. Be sure to "dispatch" or "release" locomotives and consists from throttles which use "expanded slots" before attempting to acquire the locomotive or consist via a JMRI throttle, as this may enable JMRI to acquire the locomotive or consist. This problem can affect throttles which use the JMRI WiThrottle interface and throttles controlled via the JMRI Web Server. This issue is thought to be present in all previous versions of JMRI.

(Since JMRI 4.5.6) DCC++ connections on Linux may not work.

(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 4.5.5) Apple has released a new "Sierra" version of macOS (formerly known as OS X) which has enhanced security for downloaded programs. We're providing a new form of signed download to work with this, see below. We'd be interested to hear whether that download works on older OS versions, so that we can just release this new form without having to provide separate downloads.

(Since JMRI 4.5.2) This and future versions 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) LocoTools, no longer supported since JMRI 2.10, has been removed from the Linux and OS X distributions.

(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 4.3.5) When sharing a configuration between this version and JMRI 4.3.4 or older, the older version of JMRI will not reflect changes in preferences, window position, table sorting, column order, or other user interface state. This is due to changes in how user preferences and interface state are stored.

(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 Yahoo group for help converting them, or just drop them and use the current definitions.
