   ENHANCEMENTS:
 

-    - Added the --delete-delay option, which is a more efficient way to
-      delete files at the end of the transfer without needing a separate
-      delete pass.
+    - A new incremental-recursion algorithm is now used when rsync is talking
+      to another 3.0.0 version.  This starts the transfer going more quickly
+      (before all the files have been found), and requires much less memory.
+      See the --recursive option in the manpage for some restrictions.
+
+    - The default --delete algorithm is now --delete-during when talking to a
+      3.x rsync.  This is a faster scan than using --delete-before (which is
+      the default when talking to older rsync versions), and is compatible with
+      the new incremental recursion mode.
+
+    - Added the --delete-delay option, which is a more efficient way to delete
+      files at the end of the transfer without needing a separate delete pass.
+
+    - Added the --acls (-A) option to preserve Access Control Lists.  This is
+      an improved version of the prior patch that was available.  (If you need
+      to have backward compatibility with old, patched versions, the new
+      acls.diff patch that will add that.)
+
+    - Added the --xattrs (-X) option to preserver extended attributes.  This is
+      an improved version of the prior patch that was available.  (If you need
+      to have backward compatibility with old, patched versions, the new
+      xattrs.diff patch that will add that.)

 
 

-    - 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 sure to never specify a 0
-      value to an older rsync client, or it will be silently ignored.*
+    - Added the --fake-super option that allows a non-super user to preserve
+      all attributes of a file by using a special extended-attribute idiom.
+      There is also an analogous "fake super" option for an rsync daemon.

     - The --hard-link option now uses less memory on both the sending and

+    - Rsync now has a way of handling protocol-version changes during the
+      development of a new protocol version.  This exchange of sub-version
+      info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking
+      in older versions (which would be the case if every minor change made
+      to the protocol in CVS incremented the main PROTOCOL_VERSION value).
