- * "ssh" is now the default remote shell for rsync. If you want to
- change this, configure like this: "./configure --with-rsh=rsh".
-
- * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- files read by the --*-from options. (Wayne Davison)
-
- * Length of csum2 is now per-file starting with protocol version
- 27. (J.W. Schultz)
-
- * Per-file dynamic block size is now sqrt(file length). The
- per-file checksum size is determined according to an algorithm
- provided by Donovan Baarda which reduces the probability of rsync
- algorithm corrupting data and falling back using the whole md4
- checksums. (J.W. Schultz, Donovan Baarda)
-
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
-
- * Added a new error/warning code for when files vanish from the
- sending side. Made vanished source files not interfere with the
- file-deletion pass when --delete-after was specified.
-
- * Various trailing-info sections are now preceded by a newline.
-
- BUG FIXES:
-
- * Fixed several exclude/include matching bugs when using wild-cards.
- This has a several user-visible effects, all of which make the
- matching more consistent and intuitive. This should hopefully not
- cause anyone problems since it makes the matching work more like
- what people are expecting. (Wayne Davison)
-
- - A pattern with a "**" no longer causes a "*" to match slashes.
- For example, with "/*/foo/**", "foo" must be 2 levels deep.
- [If your string has BOTH "*" and "**" wildcards, changing the
- "*" wildcards to "**" will provide the old behavior in all
- versions.]
-
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
-
- - A non-anchored wildcard term floats to match beyond the base of
- the transfer. E.g. "CVS/R*" matches at the end of the path,
- just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
- to get the old behavior in all versions.]
-
- - Including a "**" in the match term causes it to be matched
- against the entire path, not just the name portion, even if
- there aren't any interior slashes in the term. E.g. "foo**bar"
- would exclude "/path/foo-bar" (just like before) as well as
- "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
- old behavior in all versions.]
-
- * The exclude list specified in the daemon's config file is now
- properly applied to the pulled items no matter how deep the
- user's file-args are in the source tree. (Wayne Davison)
-
- * For protocol version >= 27, mdfour_tail() is called when the
- block size (including checksum_seed) is a multiple of 64.
- Previously it was not called, giving the wrong MD4 checksum.
- (Craig Barratt)
-
- * For protocol version >= 27, a 64 bit bit counter is used in
- mdfour.c as required by the RFC. Previously only a 32 bit bit
- counter was used, causing incorrect MD4 file checksums for
- file sizes >= 512MB - 4. (Craig Barratt)
-
- * Fixed a crash bug when interacting with older rsync versions and
- multiple files of the same name are destined for the same dir.

+ - 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.)
+
+ - 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.
+
+ - Added the --iconv option, which allows rsync to convert filenames from
+ one character-set to another during the transfer. The default is to make
+ this feature available as long as your system has iconv_open(). If
+ compilation fails, specify --disable-iconv to configure and rebuild. If
+ you want rsync to perform character-set conversions by default, you can
+ specify --enable-iconv=CONVERT_STRING with the default value for the
+ --iconv option that you wish to use. For example, --enable-iconv=. is a
+ good choice. See the rsync man page for an explanation of the --iconv
+ option's settings.
+
+ - 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.*
+
+ - The --hard-link option now uses less memory on both the sending and
+ receiving side for all protocol versions. For protocol 30, the use of a
+ hashtable on the sending side allows us to more efficiently convey to the
+ receiver what files are linked together. This reduces the amount of data
+ sent over the socket by a considerable margin (rather than adding more
+ data), and limits the in-memory storage of the device+inode information
+ to just the sending side for the new protocol 30, or to the receiving
+ side when speaking an older protocol (note that older rsync versions kept
+ the device+inode information on both sides).
