JMRI - Developer releases
As the program develops, we also produce test versions. You may want to try these, as new features will show up in them first. They are announced in the JMRI users email group.
The most current test release is JMRI 3.9.5. More information on it, including the links to download a copy, can be found in release note.
For more information on the rough development schedule, please see the JMRI road map (which is only occasionally updated).
