Release Notes for JMRI 5.9.8 release
Date: December 10, 2024
From: Bob Jacobsen
Subject: Test Release 5.9.8 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 hopefully the last in a series of 5.9.* test releases.
It requires at least Java 11 to work.
We recommend that you use Java 17.
(See our page on downloading Java)
We expect this series to end in the next JMRI production release in December 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.

GNU General Public License. For more information, please

- 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),

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?
