Release Notes for JMRI 4.13.4 release
Date: mmm dd, 2018
Subject: Test Release 4.13.4 of JMRI/DecoderPro is available for download.
This is a draft release note only; the download links do not yet work
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 end of 2018. (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.
Update From Older JMRI Versions
If you are currently using JMRI 4.9.6 or earlier, we strongly recommend that you update to JMRI 4.12 and make sure that's running OK before updating to this test release. There have been a number of changes in serial port support, panel file format and configuration options since those earlier releases, and moving to the stable JMRI 4.12 release is a good way to work through any possible problems.
If you are currently using JMRI 4.7.3 or earlier on Linux or macOS (Windows doesn't need this), you must update to JMRI 4.12 and carrying out the migration process described in the JMRI 4.12 release note before updating to this release.
Known problems with this release
New warnings for this release:
Older warningsSee 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 an earlier version.
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 If you are running a local web site 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
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 4.7.6 If you're having trouble getting your DCC programmer to work, try checking that the settings on the Defaults pane under Preferences window point to your hardware system. The reason: This version of JMRI (and all later) provides more options for picking the default system when you have more than one set of hardware attached The default is then 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.
During development leading to the actual release, you can find test download files on the continuous integration build page. These are development files, and might not be working at any particular time.
Changes since Test release 4.13.3:The list of included commits is available from our GitHub code repository.
JMRI Simple Server/JMRI Client
- Added the ability to see and select the DCC track signal "Idle" state within the Power Control tool. This enables JMRI users to know when the Digitrax command station has placed the track signal into the "Idle" state, and enales JMRI users to select that "Idle" state.
- Jeff Collell added Light support
New / Updated decoder definitions
Doehler & Haas
Mistral Train Models
Norsk Modelljernbane (NJM)
- Definitions for several Team Digital devices have been updated to indicate that they use Programming-on-the-Main mode even when they are only connected to the LocoNet.
- 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. These have been added to the sample scripts. (Although we might have missed a few...)
- JerryG improved some sample script documentation
- Karl Johan Lisby updated SCWarrants so they don't automatically turn off functions at end of run. This lets you keep them on if e.g. you're starting another warrant.
- Starting with this release, JMRI will create new profile directories with the suffix ".jmri". This allows them to be more properly accessed in macOS/iOS eco-system (we do it on all platforms for people who share profiles between different types of computers). It also allows people to rename their profiles (outside of JMRI, i.e. through their computer's file browser) with a .jmri ending. For more background, please see PR 5777.
