Release Notes for JMRI 4.12 release

Date: July 13, 2018

From: Bob Jacobsen

Subject: Production Release 4.12 of JMRI/DecoderPro is available for download.

We are very pleased to announce that the 4.11 series of JMRI test releases has resulted in a version that's good enough to be recommended for general use, including by new users. We're therefore making that version, "Production Release 4.12" available for download today.

Notes:

JMRI is now only available under the GNU General Public License. For more information, please see our copyright and licensing page.

Required Migration Step

Since JMRI 4.7.4

JMRI was updated in JMRI 4.7.4 to use a new serial library. Depending on your exact circumstances, you may need to do some migrations:

• If you are using JMRI on Linux or macOS / OS X and are updating from an older JMRI version, you must open the JMRI preferences and make sure that the selections are correct for your serial device(s). Be sure to save the changes.

  In general, previous versions used serial device names like "/dev/cu.usbserial-ABC123FG". This version will generally omit the prefix, and use serial device names like "cu.usbserial-ABC123FG". (If given the choice between a name starting with "tty" and one starting with "cu", pick the "cu" one). See the before and after images to the right.

• If you are using Linux and have previously used the "JMRI_SERIAL_PORTS" option to make sure your serial device is visible to JMRI, you'll have to change that to use the "purejavacomm.portnamepattern" option instead. See the JMRI Linux install page for more information.
• If you use your own JMRI scripts to access a serial device, you'll have to update their library references:
  • Any import gnu.io statements will have to be replaced by import purejavacomm statements.
  • More generally, any reference to gnu.io, e.g. a reference to a class like gnu.io.SerialPort, statements will have to be replaced by a reference to the corresponding purejavacomm class.

Known problems with this release

• This release will occasionally set the default connection to internal, which prevents programming decoders. One symptom is getting 123 every time you read a CV. This is fixed in JMRI 4.14. We recommend you update to that version.

Warnings for this release:

See the JMRI 4.10 release note for more warnings predating the 4.11 development series. These may be relevant to you if you're updating from a version earlier than JMRI 4.10.

When running JMRI using Java 9 or Java 10, the script import statements need to be fully-qualified: in addition to 'import java', you might need 'import java.beans' and others.

Since JMRI 4.11.8 Some new display capabilities were introduced into Layout Editor during JMRI 4.11-series development. This release changes some of the defaults in this area, which might change the appearance of some track segments on your panels if they're still using default values. If you select them and change their properties, then save your panel file(s), you can restore their previous appearance. There's a PDF document with more details. We apologize for the inconvenience.

Since JMRI 4.11.8 Because of changes to the "node identification" algorithm used to tell one computer running JMRI from another, you might receive a warning message about the "Node Identity" the first time you run JMRI version 4.11.8 or newer. (If you have more than one profile, this can happen with each). There's no permanent problem here, but you might have to reset your window preferences (i.e. position and size, column layout, etc) in this case. We apologize for the inconvenience.

Since JMRI 4.11.4 The additions to Layout Editor in JMRI 4.11.4 mean that files containing Layout Editor panels written by JMRI 4.11.4 or later will fail a validation check in JMRI 4.11.3 or earlier. If you back-date your JMRI version and need to to get past this, please bypass validation.

Since JMRI 4.11.4 If you are running a local website with a copy of the JMRI content, as described here, please repeat the "setSymLinks.sh" step near the bottom of those instructions after installing JMRI 4.11.4 (or later). This will make some new formatting available on your local site.

Since JMRI 4.11.4 There are issues with the Pi-SPROG One command station operation. A number of workarounds should be applied:

• Do not turn on the track power until the power supply to the Pi-SPROG ONE is turned on
• Do not enable extra debugging through default.lcf, nor open the system console window
• Do not open the SPROG console window
• Disable power conversion (CV 29) in all locos
• If connecting via VNC (or similar), setup the screen layout before turning on the track power

Pi-SPROG One with version 2.4 or earlier firmware will cause a timeout after a track short circuit. A dialog box will open to inform the user of this. The track power will be turned off and must be turned on again using the power control.

Since JMRI 4.11.2 The system connection preferences (i.e. hardware preferences) are now enforcing the correct form for system prefixes: One upper case letter, optionally followed by a number (one or more digits, e.g. "L12"). Existing prefixes in existing configurations are unchanged, but new ones will have to have the correct form.

Since JMRI 4.9.4 Due to changes in the capitalization of some method and property names, some scripts may fail until adjusted to use the new capitalization. The Javadocs for any JMRI class will list the correct capitalization.

Since JMRI 4.9.4 For Windows users only: JMRI 4.9.3 (and all later) has a new version of the "LaunchJMRI.exe" program. It's used to set options as JMRI is starting up, and is a completely normal part of JMRI. Because it's new and different, however, your anti-virus program may reject it. You might get a message about "file removed" or "file quarantined" or similar and then JMRI might not start. The solution is to make sure that your anti-virus program doesn't interfere with JMRI's installation and running. There are so many of those, unfortunately, that we can't really provide useful instructions beyond that.

Since JMRI 4.7.6 If you're having trouble getting your DCC programmer to work, try checking that the "Defaults" under "Preferences" are set to your hardware system. The reason: This version of JMRI (and all later) provides more options for "default systems": If you have multiple sets of hardware attached, which should be used for throttles, for programming, etc. JMRI tries to guess the right settings for these when you upgrade to this version, but apparently it sometimes gets that wrong (we haven't been able to track that down yet). Setting them manually fixes any wrong guesses.

Since JMRI 4.7.3 This release will not start cleanly if installed over earlier versions of JMRI (the Windows installer ensures this is not an issue). Remove the JAR files jackson-annotations-2.0.6.jar, jackson-core-2.0.6.jar, and jackson-databind-2.0.6.jar from the lib directory within the previous installation directory to resolve this.

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; these will have to be changed manually.

Since JMRI 4.7.1 When loading a panel file, JMRI applications now check the file's syntax and contents. This process is called "XML validation" If validation fails, an error message is shown that should explain the error, allowing it to be fixed using an editor. (The explanations remain a work in progress.) If you have a problem loading a panel file, please

1. Configure your JMRI startup to first run the jython/TurnOffXmlValidation.py script which will suppress the error. This script needs to be run before your panel is loaded.
2. Write out a new version of the panel file (after saving a backup!)
3. Use that new version from now on.
4. And drop use of the jython/TurnOffXmlValidation.py script.

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. 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.

Also look at JMRI-4.11.4.pdf in the Yahoo files area. It provides an overview of the changes.
• Text labels with alternate font assignments retain their formatting. (Dave Sand)
• The column widths for the Valid Paths section of the routing table adapt to the content. (Dave Sand)
• Now displays hidden mainline track sections while in edit mode.
• Fixed the View Block Routing selection list for cross-overs to use the actual block name instead of the same name for each entry.
• Dave Sand fixed a problem where the wrong default value was assigned to an unoccupied block
• Changed some of the Layout Editor appearance defaults, which might change the appearance of some track segments on your panels if they're still using default values. If you select them and change their properties, then save your panel file(s), you can restore their previous appearance. There's a PDF document with more details.

Logix

• Three new Conditional Actions have been added for Entry/Exit.
  • Set NX Pair Enabled — Enable a NX Pair. When enabled, it can used to create a route.
  • Set NX Pair Disabled — Disable a NX Pair. This will prevent the use of the pair to create a route.
  • Set NX Pair Segment Active / Inactive — If the route is not active, create the route, otherwise clear down, cancel or stack the route depending on the default actions or user response.
• Variable State and Action references to Entry/Exit Pairs now use the Entry/Exit system name. This prevents broken references caused by Entry/Exit user name changes. The conversion may find missing references which will be displayed in the system log. The affected Variable State or Action row will be deleted.
• Logix may now be shared across different Locales (languages) without losing the Mixed logic definition, e.g. english "(R1 or R2) and R3" will display and work as "(R1 oder R2) und R3" in german. To apply this on existing Logix Conditionals, open each in the original Locale and click "Update" to update the logic to the universal format. Don't forget to save the new configuration to a (new) xml file.
• Fix for nested antecedent Conditionals that would break when edited in 4.11.4. (Dave Sand)
• Antecedents are localized for display and editing but stored in English. This faciliates portability between languages. (Dave Sand)

Panel Editors

• Egbert Broerse improved how icons are previewed in the catalog
• Switchboard panels were improved to open without an Editor and with unconnected switches hidden when saved in that state. The turnout icons were fixed to match the state shown in the Turnout Table.
  You can prevent a Switchboard from operating the layout via the Editor's Option menu.
  Operating a Switchboard over JMRI Web Server and in WiThrottle has been restored.
• Text labels with alternate Font assignments retain their formatting. (Dave Sand)
• Fixed display of the icon tree chooser and drag-n-drop during icon edit in the classic Panel Editor.

Control Panel Editor

The following problems were fixed in the Item Palette:

• Text panel lost afte 2nd opening of Palette
• Background color chooser disabled after 2nd opening of Palette
• Multiple family button panels displayed after adding icons
• Inability to create new icon family sets for IndicatorTO items
• Drag icon disappears after editing existing IndicatorTO icons
• Panel background colors not shared among all Palette tabs when editors are changed
• Incorrect placement of dragged items to a zoomed panel.
• Fixed a problem when selecting Sensors, Turnouts and other items to add to a Control Panel Editor panel after sorting the items.

Turnouts, Lights and other elements

• Fixed a problem where some items would not be displayed in the table when sorted by system name
• Steve Rawlinson improved the block tracking:
  • When a block becomes occupied JMRI attempts to copy the value of an adjacent occupied block.
  • When a block's sensor becomes active 'out of nowhere' JMRI restores its previous value, if there is one. This makes sense but only in the following circumstances:
    • if the block went unoccupied very recently (to allow for sensor flicker or other momentary loss of contact)
    • if power to the layout has just been restored
    Otherwise, the new value of the block is probably not the same as it was previously.
  • Previously, JMRI always set the value, but in this release that changed such that the last value is not restored unless one of the above criteria are met. It is better, particularly on automated layouts, not to have a value than to have the wrong value.
• Fixed a bug where deleting an element from a table (e.g. Light, Turnout, Sensor, etc) would cause problems during subsequent store and load of the configuration.
• Fixed the index numbers added to the name when adding a new range of Blocks.

Signals

NX Entry/Exit Logic

• Dave Sand improved the Entry/Exit support. Entry/Exit sensor pairs can be on different Layout Editor panels that have been linked using edge connectors.
• The cross-checking between Layout Editor and Entry/Exit has been improved to prevent broken relationships that can lead to errors. Entry/Exit Help has been updated.
• Egbert Broerse improved the documentation
• The Entry/Exit system name now complies with the system name standard. The migration is automatic.
• Entry/Exit pair discovery improved to handle complex Layout Editor track plans. (Dave Sand)

Signal Masts

• Signal mast logic pair discovery improved to handle complex Layout Editor track plans. (Dave Sand)

Signal Systems

• Egbert Broerse improved the documentation, including the index pages for the individual systems
• Petr Šídlo added five sets of definitions for Czechoslovak State Railways 1962/2015 ČSD aspect signaling.
• Dick Bronson provided a new PRR 1956 signal system

Simple Signal Logic

• Egbert Broerse improved the documentation
• The set masts at slip process was displaying a dialog about a missing combo box block selection when the block has already been assigned to the slip switch. This made it impossible to assign signal masts to block boundaries at slip switches. Dave Sand fixed it.

Resources

• Chuck Catania added icons for CTC lock plates, switch heater plates, model board tower and stations.

Roster

• Digitrax Command Station Operations Switches may now be managed via a Roster entry.
• John O'Duffy improved low speed operation during speed profiling.
• The Loco Address label on the Roster Summary Print-out was corrected.

Scripting

• YetAnotherAutoTrain.py — Another script for running trains that uses English like phrases to describe the train actions.
• Scripts that access the Connection List may need to be modified. An AttributeError may occur: javax.script.ScriptException: AttributeError: type object 'jmri.InstanceManager' has no attribute 'configureManagerInstance' in <script> at line number 14. Use connectionList = jmri.InstanceManager.getDefault(jmri.jmrix.ConnectionConfigManager).getConnections()

• Sonnys Hansen improved the Danish translation for some LocoNet tools
• Petr Šídlo added to the Czech translation
• Logix may now be shared across different Locales (see note under Logix).
• Translations files for Logix and Conditional editing have been cleaned up. Users might see some english phrases. Translators please review.

Scripting

• Dave Sand's RaspberryPiShutdown.py sample script can shutdown both JMRI and the Raspberry Pi (or other Linux machine) it's running on. You can invoke via a Logix or other controls when you want to shutdown power on your layout.
• The LocoNet Scripting examples were updated to support multiple LocoNet connections. If you are using your own scripts with LocoNet, update lines of code that read

  jmri.jmrix.loconet.LnTrafficController.instance()

  to

  jmri.InstanceManager.getList(jmri.jmrix.loconet.LocoNetSystemConnectionMemo).get(0).getLnTrafficController()

  See LocoNetClasses Help.

• The Warrants Help pages were edited (with extra screen shots)
• Egbert Broerse improved the documentation
• Fix default MaxBlocks from Preferences now being used in the create warrant form.
• when running, a warrant will not allocate or throw turnouts beyond signal's stop aspect or past an occupied block. Once cleared to proceede, the warrant will set the turnouts to continue its route
• A hidden column was added to the OBlock table enabling a block to be allocated/deAllocated to a warrrant. (Reminder- "right click" the column header to make columns visible)
• The loco speed ramp algorithm was improved to make use of CV23 & CV24 in momentum determination.

Virtual Sound Decoder
