NEWS for rsync 3.0.9 (23 Sep 2011)NEWS for rsync 3.1.0 (28 Sep 2013)
Protocol: 30 (unchanged)Protocol: 31 (changed)
Changes since 3.0.8:Changes since 3.0.9:
   
     OUTPUT CHANGES:
   
       - Output numbers in 3-digit groups by default (e.g. 1,234,567).  See the
         --human-readable option for a way to turn it off.  See also the daemon's
         "log format" parameter and related command-line options (including
         --out-format) for a modifier that can be used to request digit-grouping
         or human-readable output in log escapes. (Note that log output is
         unchanged by default.)
   
       - The --list-only option is now affected by the --human-readable setting.
         It will display digit groupings by default, and unit suffixes if higher
         levels of readability are requested.  Also, the column width for the size
         output has increased from 11 to 14 characters when human readability is
         enabled.  Use --no-h to get the old-style output and column size.
   
       - The output of the --progress option has changed:  the string "xfer" was
         shortened to "xfr", and the string "to-check" was shortened to "to-chk",
         both designed to make room for the (by default) wider display of file
         size numbers without making the total line-length longer.  Also, when
         incremental recursion is enabled, the string "ir-chk" will be used
         instead of "to-chk" up until the incremental-recursion scan is done,
         letting you know that the value to check and the total value will still
         be increasing as new files are found.
   
       - Enhanced the --stats output: 1) to mention how many files were created
         (protocol >= 28), 2) to mention how many files were deleted (a new line
         for protocol 31, but only output when --delete is in effect), and 3) to
         follow the file-count, created-count, and deleted-count with a subcount
         list that shows the counts by type.  The wording of the transferred count
         has also changed so that it is clearer that it is only a count of regular
         files.
   
   BUG FIXES:    BUG FIXES:
   
    - Fix a crash bug in checksum scanning when --inplace is used.    - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
       full output buffer.
   
    - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.    - Fixed some rare bugs in --iconv processing that might cause a multibyte
      if it has no read permission).      character to get translated incorrectly.
   
    - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.    - Fixed a bogus "vanished file" error if some files were specified with
       "./" prefixes and others were not.
   
    - Fix a memory leak in the xattr code.    - Fixed a bug in --sparse where an extra gap could get inserted after a
       partial write.
   
    - Fixed a bug with --delete-excluded when a filter merge file has a rule    - Changed the way --progress overwrites its prior output in order to make
      that specifies a receiver-only side restriction.      it nearly impossible for the progress to get overwritten by an error.
   
    - Fix a bug with the modifying of unwritable directories.    - Improved the propagation of abnormal-exit error messages.  This should
       help the client side to receive errors from the server when it is exiting
       abnormally, and should also avoid dying with an "connection unexpectedly
       closed" exit when the closed connection is really expected.
   
    - Fix --fake-super's interaction with --link-dest same-file comparisons.    - The sender now checks each file it plans to remove to ensure that it
       hasn't changed from the first stat's info.  This helps to avoid losing
       file data when the user is not using the option in a safe manner.
   
    - Fix the updating of the curr_dir buffer to avoid a duplicate slash.    - Fixed a data-duplication bug in the compress option that made compression
       less efficient.  This improves protocol 31 onward, while behaving in a
       compatible (buggy) manner with older rsync protocols.
   
    - Fix the directory permissions on an implied dot-dir when using --relative    - When creating a temp-file, rsync is now a bit smarter about it dot-char
      (e.g. /outside/path/././send/path).      choices, which can fix a problem on OS X with names that start with "..".
   
    - Fixed some too-long sleeping instances when using --bwlimit.    - Rsync now sets a cleanup flag for --inplace and --append transfers that
       will flush the write buffer if the transfer aborts.  This ensures that
       more received data gets written out to the disk on an aborted transfer
       (which is quite helpful on a slow, flaky connection).
   
    - Fixed when symlink ownership difference-checking gets compiled into    - The reads that map_ptr() now does are aligned on 1K boundaries.  This
      unchanged_attrs().      helps some filesystems and/or files that don't like unaligned reads.
   
    - Improved the socket-error reporting when multiple protocols fail.    - Fix an issue in the msleep() function if time jumps backwards.
   
    - Fixed a case where a socket error could reference just-freed memory.    - Fix daemon-server module-name splitting bug where an arg would get split
       even if --protect-args was used.
   
    - Failing to use a password file that was specified on the command-line is  ENHANCEMENTS:
      now a fatal error. 
   
    - Fix the non-root updating of directories that don't have the read and/or    - Added the --remote-option=OPT (-M OPT) command-line option that is useful
      execute permission.      for things like sending a remote --log-file=FILE or --fake-super option.
   
    - Make daemon-excluded file errors more error-like.    - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
       control over what is output.  Added an extra type of --progress output
       using --info=progress2.
   
    - Fix a compilation issue on older C compilers (due to a misplaced var    - The --msgs2stderr option can help with debugging rsync by allowing the
      declaration).      debug messages to get output to stderr rather than travel via the socket
       protocol.
   
    - Make configure avoid finding socketpair on cygwin.    - Added the --delete-missing-args and --ignore-missing-args options to
       either delete or ignore user-specified files on the receiver that are
       missing on the sender (normally the absence of user-specified files
       generates an error).
   
    - Avoid trying to reference SO_BROADCAST if the OS doesn't support it.    - Added a "T" (terabyte) category to the --human-readable size suffixes.
   
    - Fix some issues with the post-processing of the man pages.    - Added the --usermap/--groupmap/--chown options for manipulating file
       ownership during the copy.
   
    - Fixed the user home-dir handling in the support/lsh script.    - Added the "%C" escape to the log-output handling, which will output the
       MD5 checksum of any transferred file, or all files if --checksum was
       specified (when protocol 30 or above is in effect).
   
    - Some minor manpage improvements.    - Added the "reverse lookup" parameter to the rsync daemon config file to
       allow reverse-DNS lookups to be disabled.
 
     - Added a forward-DNS lookup for the daemon's hosts allow/deny config.  Can
       be disabled via "forward lookup" parameter (defaults to enabled).
 
     - Added a way for more than one group to be specified in the daemon's
       config file, including a way to specify that you want all of the
       specified user's groups without having to name them.  Also changed the
       daemon to complain about an inability to set explicitly-specified uid/gid
       values, even when not run by a super-user.
 
     - The daemon now tries to send the user the error messages from the
       pre-xfer exec script when it fails.
 
     - Improved the use of alt-dest options into an existing hierarchy of files:
       If a match is found in an alt-dir, it takes precedence over an existing
       file.  (We'll need to wait for a future version before attribute-changes
       on otherwise unchanged files are safe when using an existing hierarchy.)
 
     - Added per-user authorization options and group-authorization support to
       the daemon's "auth users" parameter.
 
     - Added a way to reference environment variables in a daemon's config file
       (using %VAR% references).
 
     - When replacing a non-dir with a symlink/hard-link/device/special-file,
       the update should now be done in an atomic manner.
 
     - Avoid re-sending xattr info for hard-linked files w/the same xattrs
       (protocol 31).
 
     - The backup code was improved to use better logic maintaining the backup
       directory hierarchy.  Also, when a file is being backed up, rsync tries
       to hard-link it into place so that the upcoming replacement of the
       destination file will be atomic (for the normal, non-inplace logic).
 
     - Added the ability to synchronize nano-second modified times.
 
     - Added a few more default suffixes for the "dont compress" settings.
 
     - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
       the default for the --protect-args command-line option to be overridden.
 
     - Added the --preallocate command-line option.
 
     - Allow --password-file=- to read the password from stdin (filename "-").
 
     - Rsync now comes packaged with an rsync-ssl helper script that can be
       used to contact a remote rsync daemon using a piped-stunnel command.
       It also includes an stunnel config file to run the server side to
       support ssl daemon connections.  See the packaging/lsb/rsync.spec
       file for one way to package the resulting files.  (Suggestions for
       how to make this even easier to install & use are welcomed.)
 
     - Improved the speed of some --inplace updates when there are lots of
       identical checksum blocks that end up being unusable.
 
     - Added the --outbuf=N|L|B option for choosing the output buffering.
 
     - Repeating the --fuzzy option now causes the code to look for fuzzy
       matches inside alt-dest directories too.
 
     - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
 
     - Added some Solaris xattr code.
 
     - Made an rsync daemon (the listening process) exit with a 0 status when
       it was signaled to die.  This helps launchd.
 
     - Improved the RSYNC_* environment variables for the pre-xfer exec script:
       when a daemon is sent multiple request args, they are now joined into a
       single return value (separated by spaces) so that the RSYNC_REQUEST
       environment variable is accurate for any "pre-xfer exec".  The values in
       RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
       request dirs/files), so that all the requested values are also listed
       (separately) in RSYNC_ARG# variables.
 
   EXTRAS:
 
     - Added an "instant-rsyncd" script to the support directory, which makes
       it easy to configure a simple rsync daemon in the current directory.
 
     - Added the "mapfrom" and "mapto" scripts to the support directory, which
       makes it easier to do user/group mapping in a local transfer based on
       passwd/group files from another machine.
 
     - There's a new, improved version of the lsh script in the support dir:
       it's written in perl and supports -u without resorting to using sudo
       (when run as root).  The old shell version is now named lsh.sh.
 
     - There is a helper script named rsync-slash-strip in the support directory
       for anyone that wants to change the way rsync handles args with trailing
       slashes.  (e.g. arg/ would get stripped to arg while arg/. would turn into
       arg/).
 
   INTERNAL:
 
     - The I/O code was rewritten to be simpler and do bigger buffered reads
       over the socket.  The I/O between the receiver and the generator was
       changed to be standard multiplexed-I/O (like that over the socket).
 
     - The sender tries to use any dead time while the generator is looking for
       files to transfer in order to do sender-side directory scanning in a more
       parallel manner.
 
     - A daemon can now inform a client about a daemon-configured timeout value
       so that the client can assist in the keep-alive activity (protocol 31).
 
     - The filter code received some refactoring to make it more extendible, to
       read better, and do better sanity checking.
 
     - Really big numbers are now output using our own big-num routine rather
       than casting them to a double and using a %.0f conversion.
 
     - The pool_alloc library has received some minor improvements in alignment
       handling.
 
     - Added init_stat_x() function to avoid duplication of acl/xattr init code.
 
     - The included zlib was upgraded from 1.2.3 to 1.2.8.
 
     - Rsync can now be compiled to use an unmodified zlib library instead of
       the tweaked one that is included with rsync.  This will eventually
       become the default, at which point we'll start the countdown to removing
       the included zlib.  Until then, feel free to configure using:
 
         ./configure --with-included-zlib=no
