1.7.3 release notes
From Jmri
getchil The original release note contains a list of changes in the release. This page contains more recent information.
Recent experience suggests that you need to be aware of a few gotcha's if you're installing for the first time. Specifically:
Digitrax Command Station Editor
This is a new feature in this release. Opened from the 'tools' menu it allows you to program (mess up?) your command station from within JMRI. Unfortunately, Digitrax' naming convention and defaults for these options remains about as clear as mud, so use at your own risk, probably only after saving the current configuration.
Also note, it reads and writes these values very quickly, so it's probably working even if you think it isn't! (Don't ask) - When you write anything back to a Zephyr command station you should see (something like) --CS-- flash *very*briefly* in the command station display.
