     - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
 
+    - The sender now skips a (bogus) symlink that has a 0-length value, which
+      avoids a transfer error in the receiver.

     - Fixed the rrsync script to avoid a server-side problem when -e is at the
       start of the short options.
