- - Added the --only-write-batch=FILE option that may be used (instead
- of --write-batch=FILE) to create a batch file without doing any
- actual updating of the destination.
-
- - Changed the outputting of "safe" filenames to use backslash-escaped
- characters rather than '?'s. Any non-printable character is output
- using octal (e.g. "\n" -> "\012"), and backslash is output as "\\".
-
- - Improved the auth-errors that are logged for the daemon to include
- some information on why the authorization failed (wrong user,
- password mismatch, etc.).
-
- - Improved the client's handling of an "@ERROR" from a daemon so that
- it does not complain about an unexpectedly closed socket (since we
- really did expect the socket to close).
+ - You may specify --max-delete=0 to a 3.0.0 client as long as the
+ receiving side is at least version 3.0.0. This means that you
+ can pull from an older rsync with this option, but pushing to an
+ older rsync will generate an error. *Be careful to never specify
+ a 0 value to older rsync client, or it will be silently ignored.*
