Release Notes for JMRI 5.1.2 release
Date: July 10, 2022
From: Bob Jacobsen
Subject: Test Release 5.1.2 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 5.1.* 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 5.2 production release in December 2022.
(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.

GNU General Public License. For more information, please

Update From Older JMRI Versions
If you are currently using a version older than JMRI 4.24, 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.
- 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.
New problems with this release
- Since JMRI 4.99.9
There's a problem adding NCE AIU sensors using the NS50:1 format.
As a workaround, you can add them with the full numeric address: NS123.
The fix will be available in JMRI 5.1.3
New warnings for this release:
Older warnings
See the
JMRI 5.0 release note for more warnings predating the 5.1 development series,
including pointers to various migration issues.
These may be relevant to you if you're updating from an earlier version;
we strongly recommend you update to at least
JMRI 4.20
before installing this test release.
- 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 4.99.1
This version no longer reads ZeroConf IPv4 and IPv6 preferences
written with JMRI 4.16 and before. Please make sure to upgrade
to JMRI 4.20 (or later) and save your preferences before
updating to this version if you have configured the WiThrottle preference pane.

Hardware Support
MQTT
- Rewrite and expansion of documentation.
- The default value of the channel is now "", the null string.
The channel name is prefixed to all of JMRI's publish and subscribe
operations. The previous default was "/trains/"

messages and replies would be echoed out incorrectly.
LogixNG
- The action Listen On Beans now sorts the named beans when selecting a bean to listen on.
Operations
- Enhanced passenger blocking. Negative blocking numbers place passenger cars in front of
freight cars.
- Added hazardous classification to car loads. Now a car can be classified as hazardous
depending on the car's load.

non-hazardous cars in front of hazardous cars.
