• The jmri.jmrix.SystemConnectionMemo class has become a jmri.SystemConnectionMemo interface and a jmri.jmrix.DefaultSystemConnectionMemo class. This may require changes to scripts. If you have a script that references jmri.jmrix.SystemConnectionMemo, please change it to either jmri.SystemConnectionMemo or jmri.jmrix.DefaultSystemConnectionMemo (it's easier to have you just try the two than to explain which one will work in which case)
