+ --link-dest and a parallel hierarchy of files to effect its update.
+
+ - Added support/mnt-excl that takes the /proc/mounts file and
+ translates it into a set of excludes that will exclude all mount
+ points (even mapped mounts to the same disk). The excludes are made
+ relative to the specified source dir and properly anchored.
+
+ - Added support/savetransfer.c -- a C program that can make a copy of
+ all the data that flows over the wire. This lets you test for data
+ corruption (by saving the data on both the sending side and the
+ receiving side) or provides a way to help debug a protocol error.
+
+ - Added support/rrsync -- my version of Joe Smith's restricted rsync
+ perl script. This helps to ensure that only certain rsync commands
+ can be run by an ssh invocation.
+
+ - Improved the option descriptions in the --help text.
+
+ INTERNAL:
+
+ - Added better checking of the checksum-header values that come over
+ the socket.
+
+ - Merged the various delete-file functions into a single function so
+ that it is easier to maintain.
+
+ - Improved the type of some variables (particularly blocksize vars) for
+ consistency and proper size.
+
+ - Got rid of the uint64 type (which we didn't need).
+
+ - Use a slightly more compatible set of core #include directives.
+
+ - Defined int32 in a way that ensures that the build dies if we can't
+ find a variable with at least 32 bits.
+
+ PROTOCOL DIFFERENCES FOR VERSION 29:
+
+ - If --inplace is specified, the generator sends an extra byte after
+ each index integer indicating what kind of basis file is being used
+ for the transfer (see the FNAMECMP_* defines).
+
+ - The sending of exclude names is done using filter-rule syntax. This
+ means that all names have a prefixed rule indicator, even excludes
+ (which used to be sent as a bare pattern, when possible). The -C
+ option will include the per-dir .cvsignore merge file in the list of
+ filter rules so it is positioned correctly (unlike in some older
+ transfer scenarios).
+
+ - Rsync sorts the filename list in a different way: it sorts the
+ subdir names after the non-subdir names for each dir's contents, and
+ it always puts a dir's contents immediately after the dir's name in
+ the list. (Previously an item named "foo.txt" would sort in between
+ directory "foo/" and "foo/bar".)
+
+ - When talking to a protocol 29 rsync daemon, a list-only request
+ is able to note this before the options are sent over the wire, and
+ the new --list-only option is enabled.
+
+ - When the --stats bytes are sent over the wire (or stored in a batch),
+ they now include two elapsed-time values: one for how long it took to
+ build the file-list, and one for how long it took to send it over the
+ wire (each expressed in thousandths of a second).
+
+ - When --delete-excluded is specified with some filter rules (AKA
+ excludes), a client sender will still initiate a send of the filter
+ rules to the receiver, but it only includes those rules that are
+ receiver-specific. Older protocols used to omit the sending of
+ excludes in this situation (since there were no receiver-specific
+ rules that survived --delete-excluded back then).
+
+ - A protocol-29 batch file includes a bit for the setting of the --dirs
+ option. Also, the shell script created by --write-batch will use the
+ --filter option instead of --exclude-from to capture any filter rules.
