 - Reassigning the Execute Query, Execute All Statements, and Cancel Query shortcuts now takes effect, and the Query menu shows the new keys (#1357)
 - Custom shortcuts now require a modifier key, so a plain key like Space is no longer accepted and then silently ignored (#1357)
 - Cancelling a pending connection no longer lets the abandoned attempt overwrite or drop a later successful connection to the same database (#1358)
+- Cancelling a pending SSH connection now closes its tunnel instead of leaving the local forward port open (#1369)
