Release Notes for JMRI 5.7.9 release
Date: June 17, 2024
From: Bob Jacobsen
Subject: Test Release 5.7.9 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 5.7.* test releases.
It requires Java 11 to work.
(See our page on downloading Java 11)
We expect this series to end in the next JMRI 5.8 production release in June 2024.
(See the tentative release schedule)
We are getting close to the next production release, so we would particularly
appreciate your testing of this release to make sure it works for you. That way,
if you find new problems, we can try to fix them before the production release.
JMRI is now only available under the
GNU General Public License. For more information, please

Update From Older JMRI Versions
If you are currently using a version older than JMRI 5.0, please follow these instructions carefully:
- Is your current version older than JMRI 4.12?
If so, then update to JMRI 4.12 first, and ensure everything works correctly: check
start-up, check things you need to be working, and check the JMRI log as well) before doing anything else.
Store your configuration and panel files under a new name and use those from now on.
Then continue with step 2.
If you are currently using JMRI 4.7.3 or earlier on Linux or macOS (Windows doesn't need this),
then it's very important
that you update to JMRI 4.12 and
carrying out the migration process described in the JMRI 4.12 release note
before updating to any later release.
- Is your current version older than JMRI 4.20?
Then update to JMRI 4.20 first, and ensure that works correctly (check
start-up, check things you need to be working, and check the JMRI log as well) before doing anything else.
Save your preferences again.
Store your configuration and panel files under a new name, use those from now on, and go on to step 3.
- Is your current version older than JMRI 4.24?
Then update to JMRI 4.24 first, and ensure that works correctly (check
start-up, check things you need to be working, and check the JMRI log as well) before doing anything else.
Save your preferences again.
Store your configuration and panel files under a new name and use those from now on.
- Is your current version older than JMRI 5.0?
Then update to JMRI 5.0 first, and ensure that works correctly (check
start-up, check things you need to be working, and check the JMRI log as well) before doing anything else.
Save your preferences again.
Store your configuration and panel files under a new name and use those from now on.
- You can then install this release.
Following this multi-step order of updating via stable major releases safeguards you against possible migration issues
that can arise from skipping these versions.

See the
JMRI 5.6 release note for more warnings predating the 5.7 development series,

- Since JMRI 4.7.7
If you are using a RR-CirKits LocoNet to LCC gateway
with this release, please upgrade its firmware
to version B8g or later. B8f or earlier will
have trouble updating the gateway's configuration.
- Since JMRI 4.99.1
This test release, and all subsequent ones, require the use of
Java 11 or later. Java 8 is explicitly not supported.
There's more information on this migration on the
JMRI Tech Road Map and
JVM Capabilities pages.
- Since JMRI 5.5.3
Scripts that output Logging statements with log4jv1.x ( org.apache.log4j ) imports will stop working
from JMRI 5.5.4 and should be updated to use SLF4J logging.
See here for some examples on how to do this.
- Since JMRI 5.5.4
Custom default.lcf Logging Control Files will cease to take effect from JMRI 5.5.4
To create a custom default_lcf.xml in the new Logging Configuration format, see
JMRI Debugging and Logging

XML files with table contents and panels have been changed in JMRI 5.5.5. It's therefore not

later with a JMRI version pre 5.5.5.
- Since JMRI 5.5.5
MQTT Connection - Throttle loco address and function placeholders in MQTT topics have changed from
$address and $function to {0} and {1} for consistency with other objects.
