+ - When --copy-links (-L) is specified, we now output a separate error
+ for a symlink that has no referent instead of claiming that a file
+ "vanished".
+
+ - Error messages from the daemon server's option-parsing (such as
+ refused options) now get sent back to the client (the server used
+ to just exit because the socket wasn't in the right state to send
+ the message).
+
+ - Most errors that occur during a daemon transfer are now returned to
+ the user in addition to being logged (some messages are intended to
+ be daemon-only).
