*) incorporated all the bugfixes since v3.30;
*) port remote-access - added 'log-file' property. If value is a non-empty
string, then all data that is read from the port is appended to a file
with that name, regardless of the active remote connection;
*) console - removed '/user' from the output of top level '/export' command,
still can be exported by '/user export';
RC in the name means "Release Candidate", ie. the v4 is out of beta
