+NEWS for rsync 2.6.7 (11 Mar 2006)
+
 Protocol: 29 (unchanged)
-Changes since 2.6.4:
+Changes since 2.6.6:
 
   OUTPUT CHANGES:
 
-    - Non-printable chars in filenames are now output using backslash-
-      escaped characters rather than '?'s.  Any non-printable character is
-      output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
-      is now output as "\\".  Rsync also uses your locale setting, which
-      can make it treat fewer high-bit characters as non-printable.
+    - The letter 'D' in the itemized output was being used for both devices
+      (character or block) as well as other special files (such as fifos and
+      named sockets).  This has changed to separate non-device special files
+      under the 'S' designation (e.g. "cS+++++++ path/fifo").  See also the
+      "--specials" option, below.
 
-    - If rsync received an empty file-list when pulling files, it would
-      output a "nothing to do" message and exit with a 0 (success) exit
-      status, even if the remote rsync returned an error (it did not do
-      this under the same conditions when pushing files).  This was changed
-      to make the pulling behavior the same as the pushing behavior:  we
-      now do the normal end-of-run outputting (depending on options) and
-      exit with the appropriate exit status.
+    - The way rsync escapes unreadable characters has changed.  First, rsync
+      now has support for recognizing valid multibyte character sequences in
+      your current locale, allowing it to escape fewer characters than before
+      for a locale such as UTF-8.  Second, it now uses an escape idiom of
+      "\#123", which is the literal string "\#" followed by exactly 3 octal
+      digits.  Rsync no longer doubles a backslash character in a filename
+      (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
+      escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
+      (e.g. it will output "foo\#134#789" when copying "foo\#789").  See also
+      the --8-bit-output (-8) option, mentioned below.
+
+      Script writers: the local rsync is the one that outputs escaped names,
+      so if you need to support unescaping of filenames for older rsyncs, I'd
+      suggest that you parse the output of "rsync --version" and only use the
+      old unescaping rules for 2.6.5 and 2.6.6.
 
   BUG FIXES:
 
-    - A crash bug was fixed when a daemon had its "path" set to "/", did
-      not have chroot enabled, and used some anchored excludes in the
-      rsyncd.conf file.
+    - Fixed a really old bug that caused --checksum (-c) to checksum all the
+      files encountered during the delete scan (ouch).
 
-    - Fixed a bug in the transfer of a single file when -H is specified
-      (rsync would either infinite loop or perhaps crash).
+    - Fixed a potential hang in a remote generator:  when the receiver gets a
+      read-error on the socket, it now signals the generator about this so that
+      the generator does not try to send any of the terminating error messages
+      to the client (avoiding a potential hang in some setups).
 
-    - Fixed a case where the generator might try (and fail) to tweak the
-      write-permissions of a read-only directory in list-only mode (this
-      only caused an annoying warning message).
+    - Made hard-links work with symlinks and devices again.
 
-    - If --compare-dest or --link-dest uses a locally-copied file as the
-      basis for an updated version, log this better when --verbose or -i
-      is in effect.
+    - If the sender gets an early EOF reading a source file, we propagate this
+      error to the receiver so that it can discard the file and try requesting
+      it again (which is the existing behavior for other kinds of read errors).
 
-    - Fixed the accidental disabling of --backup during the --delete-after
-      processing.
+    - If a device-file/special-file changes permissions, rsync now updates the
+      permissions without recreating the file.
 
-    - Restored the ability to use the --address option in client mode (in
-      addition to its use in daemon mode).
+    - If the user specifies a remote-host for both the source and destination,
+      we now output a syntax error rather than trying to open the destination
+      hostspec as a filename.
 
-    - Make sure that some temporary progress information from the delete
-      processing does not get left on the screen when it is followed by a
-      newline.
+    - When --inplace creates a new destination file, rsync now creates it with
+      permissions 0600 instead of 0000 -- this makes restarting possible when
+      the transfer gets interrupted in the middle of sending a new file.
 
-    - When --existing skips a directory with extra verbosity, refer to it
-      as a "directory", not a "file".
+    - Reject the combination of --inplace and --sparse since the sparse-output
+      algorithm doesn't work when overwriting existing data.
 
-    - When transferring a single file to a different-named file, any
-      generator messages that are source-file related no longer refer to
-      the file by the destination filename.
+    - Fixed the directory name in the error that is output when pop_dir()
+      fails.
 
-    - Fixed a bug where hard-linking a group of files might fail if the
-      generator hasn't created a needed destination directory yet.
+    - Really fixed the parsing of a "!" entry in .cvsignore files this time.
 
-    - Fixed a bug where a hard-linked group of files that is newly-linked
-      to a file in a --link-dest dir doesn't link the files from the rest
-      of the cluster.
+    - If the generator gets a stat() error on a file, output it (this used to
+      require at least -vv for the error to be seen).
 
-    - When deleting files with the --one-file-system (-x) option set, rsync
-      no longer tries to remove files from inside a mount-point on the
-      receiving side.  Also, we don't complain about being unable to remove
-      the mount-point dir.
+    - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+      the exit status properly and generate a better error.
 
-    - Fixed a compatibility problem when using --cvs-ignore (-C) and
-      sending files to an older rsync without using --delete.
+    - Fixed some glitches in the double-verbose output when using --copy-dest,
+      --link-dest, or --compare-dest.  Also improved how the verbose output
+      handles hard-links (within the transfer) that had an up-to-date alternate
+      "dest" file, and copied files (via --copy-dest).
 
-    - Make sure that a "- !" or "+ !" include/exclude pattern does not
-      trigger the list-clearing action that is reserved for "!".
+    - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+      that have a path component containing a slash.
 
-    - Avoid a timeout in the generator when the sender/receiver aren't
-      handling the generator's checksum output quickly enough.
+    - If code reading a filter/exclude file an EINTR error, rsync now clears
+      the error flag on the file handle so it can keep on reading.
 
-    - Fixed the omission of some directories in the delete processing when
-      --relative (-R) was combined with a source path that had a trailing
-      slash.
+    - If --relative is active, the sending side cleans up trailing "/" or "/."
+      suffixes to avoid triggering a bug in older rsync versions.  Also, we now
+      reject a ".." dir if it would be sent as a relative dir.
 
-    - Fixed a case where rsync would erroneously delete some files and then
-      re-transfer them when the options --relative (-R) and --recursive
-      (-r) were both enabled (along with --delete) and a source path had a
-      trailing slash.
+    - If a non-directory is in the way of a directory and rsync is run with
+      --dry-run and --delete, rsync no longer complains about not being able
+      to opendir() the not-yet present directory.
 
-    - Make sure that --max-size doesn't affect a device or a symlink.
+    - When --list-only is used and a non-existent local destination dir was
+      also specified as a destination, rsync no longer generates a warning
+      about being unable to create the missing directory.
 
-    - Make sure that a system with a really small MAXPATHLEN does not cause
-      the buffers in readfd_unbuffered() to be too small to receive normal
-      messages.  (This mainly affected Cygwin.)
+    - Fixed some problems with --relative --no-implied-dirs when the
+      destination directory did not yet exist:  we can now create a symlink or
+      device when it is the first thing in the missing dir, and --fuzzy no
+      longer complains about being unable to open the missing dir.
 
-    - If a source pathname ends with a filename of "..", treat it as if
-      "../" had been specified (so that we don't copy files to the parent
-      dir of the destination).
+    - Fixed a bug where the --copy-links option would not affect implied
+      directories without --copy-unsafe-links (see --relative).
 
-    - If --delete is combined with a file-listing rsync command (i.e. no
-      transfer is happening), avoid outputting a warning that we couldn't
-      delete anything.
+    - Got rid of the need for --force to be used in some circumstances with
+      --delete-after (making it consistent with --delete-before/-during).
 
-    - If --stats is specified with --delete-after, ensure that all the
-      "deleting" messages are output before the statistics.
+    - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
+      when a file is too large (rsync handles the write error).
 
-    - Improved one "if" in the deletion code that was only checking errno
-      for ENOTEMPTY when it should have also been checking for EEXIST (for
-      compatibility with OS variations).
+    - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
+      was not properly padded with trailing '=' chars.  This only affects a
+      user that need to use a password-authenticated proxy for an outgoing
+      daemon-rsync connection.
+
+    - If we're transferring an empty directory to a new name, rsync no longer
+      forces S_IWUSR if it wasn't already set, nor does it accidentally leave
+      it set.
+
+    - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
+      checksum for the current file offset.
+
+    - Rsync no longer allows a single directory to be copied over a non-
+      directory destination arg.
 
   ENHANCEMENTS:
 
-    - Added the --only-write-batch=FILE option that may be used (instead
-      of --write-batch=FILE) to create a batch file without doing any
-      actual updating of the destination.  This allows you to divert all
-      the file-updating data away from a slow data link (as long as you
-      are pushing the data to the remote server when creating the batch).
+    - Added the --append option that makes rsync append data onto files that
+      are longer on the source than the destination (this includes new files).
 
-    - When the generator is taking a long time to fill up its output buffer
-      (e.g. if the transferred files are few, small, or missing), it now
-      periodically flushes the output buffer so that the sender/receiver
-      can get started on the files sooner rather than later.
+    - Added the --min-size=SIZE option to exclude small files from the
+      transfer.
 
-    - Improved the keep-alive code to handle a long silence between the
-      sender and the receiver that can occur when the sender is receiving
-      the checksum data for a large file.
+    - Added the --compress-level option to allow you to set how aggressive
+      rsync's compression should be (this option implies --compress).
 
-    - Improved the auth-errors that are logged by the daemon to include
-      some information on why the authorization failed:  wrong user,
-      password mismatch, etc.  (The client-visible message is unchanged!)
+    - Enhanced the parsing of the SIZE value for --min-size and --max-size to
+      allow easy entry of multiples of 1000 (instead of just multiples of 1024)
+      and off-by-one values too (e.g. --max-size=8mb-1).
 
-    - Improved the client's handling of an "@ERROR" from a daemon so that
-      it does not complain about an unexpectedly closed socket (since we
-      really did expect the socket to close).
+    - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
+      high-bit characters that it thinks are unreadable in the current locale.
 
-    - If the daemon can't open the log-file specified in rsyncd.conf, fall
-      back to using syslog and log an appropriate warning.  This is better
-      than what was typically a totally silent (and fatal) failure (since a
-      daemon is not usually run with the --no-detach option that was
-      necessary to see the error on stderr).
+    - The new option --human-readable (-h) changes the output of --progress,
+      --stats, and the end-of-run summary to be easier to read.  If repeated,
+      the units become powers of 1024 instead of powers of 1000.  (The old
+      meaning of -h, as a shorthand for --help, still works as long as you
+      just use it on its own, as in "rsync -h".)
 
-    - The man pages now consistently refer to an rsync daemon as a "daemon"
-      instead of a "server" (to distinguish it from the server process in a
-      non-daemon transfer).
+    - If lutimes() and/or lchmod() are around, use them to allow the
+      preservation of attributes on symlinks.
 
-    - Made a small change to the rrsync script (restricted rsync -- in the
-      support dir) to make a read-only server reject all --remove-* options
-      when sending files (to future-proof it against the possibility of
-      other similar options being added at some point).
+    - The --link-dest option now affects symlinks and devices (when possible).
+
+    - Added two config items to the rsyncd.conf parsing:  "pre-xfer exec" and
+      "post-xfer exec".  These allow a command to be specified on a per-module
+      basis that will be run before and/or after a daemon-mode transfer.  (See
+      the man page for a list of the environment variables that are set with
+      information about the transfer.)
+
+    - When using the --relative option, you can now insert a dot dir in
+      the source path to indicate where the replication of the source dirs
+      should start.  For example, if you specify a source path of
+      rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
+      replicate the "baz/dir" part of the source path (note: a trailing
+      dot dir is unaffected unless it also has a trailing slash).
+
+    - Added some new --no-FOO options that make it easier to override unwanted
+      implied or default options.  For example, "-a --no-o" (aka "--archive
+      --no-owner") can be used to turn off the preservation of file ownership
+      that is implied by -a.
+
+    - Added the --chmod=MODE option that allows the destination permissions to
+      be changed from the source permissions.  E.g. --chmod=g+w,o-rwx
+
+    - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
+      a module to specify what permissions changes should be applied to all
+      files copied to and from the daemon.
+
+    - Allow the --temp-dir option to be specified when starting a daemon, which
+      sets the default temporary directory for incoming files.
+
+    - If --delete is combined with --dirs without --recursive, rsync will now
+      delete in any directory whose content is being synchronized.
+
+    - If --backup is combined with --delete without --backup-dir (and without
+      --delete-excluded), we add a "protect" filter-rule to ensure that files
+      with the backup suffix are not deleted.
+
+    - The file-count stats that are output by --progress were improved to
+      better indicate what the numbers mean.  For instance, the output:
+      "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
+      to be transferred, and we still need to check 8383 more files out of
+      a total of 9999.
+
+    - The include/exclude code now allows a dir/*** directive (with 3 trailing
+      stars) to match both the dir itself as well as all the content below the
+      dir (dir/** would not match the dir).
+
+    - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
+      discard empty chains of directories from the file-list.  This makes it
+      easier to selectively copy files from a source hierarchy and end up with
+      just the directories needed to hold the resulting files.
+
+    - If the --itemize-changes (-i) option is repeated, rsync now includes
+      unchanged files in the itemized output (similar to -vv, but without all
+      the other verbose messages that can get in the way).  Of course, the
+      client must be version 2.6.7 for this to work, but the remote rsync only
+      needs to be 2.6.7 if you're pushing files.
+
+    - Added the --specials option to tell rsync to copy non-device special
+      files (which rsync now attempts even as a normal user).  The --devices
+      option now requests the copying of just devices (character and block).
+      The -D option still requests both (e.g. --devices and --specials), -a
+      still implies -D, and non-root users still get a silent downgrade that
+      omits device copying.
+
+    - Added the --super option to make the receiver always attempt super-user
+      activities.  This is useful for systems that allow things such as devices
+      to be created or ownership to be set without being UID 0, and is also
+      useful for someone who wants to ensure that errors will be output if the
+      receiving rsync isn't being run as root.
+
+    - Added the --sockopts option for those few who want to customize the TCP
+      options used to contact a daemon rsync.
+
+    - Added a way for the --temp-dir option to be combined with a partial-dir
+      setting that lets rsync avoid non-atomic updates (for those times when
+      --temp-dir is not being used because space is tight).
+
+    - A new support script, files-to-excludes, will transform a list of files
+      into a set of include/exclude directives that will copy those files.
+
+    - A new option, --executability (-E) can be used to preserve just the
+      execute bit on files, for those times when using the --perms option is
+      not desired.
+
+    - The daemon now logs each connection and also each module-list request
+      that it receives.
+
+    - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+      (permission bits, e.g. "rwxr-xrwt").
+
+    - The --dry-run option no longer forces the enabling of --verbose.
+
+    - The --remove-sent-files option now does a better job of incrementally
+      removing the sent files on the sending side (older versions tended to
+      clump up all the removals at the end).
+
+    - A daemon now supersedes its minimal SIGCHLD handler with the standard
+      PID-remembering version after forking.  This ensures that the generator
+      can get the child-exit status from the receiver.
+
+    - Use of the --bwlimit option no longer interferes with the remote rsync
+      sending error messages about invalid/refused options.
+
+    - Rsync no longer returns a usage error when used with one local source arg
+      and no destination: this now implies the --list-only option, just like
+      the comparable situation with a remote source arg.
+
+    - Added the --copy-dirlinks option, a more limited version of --copy-links.
+
+    - Various documentation improvements, including: a better synopsis, some
+      improved examples, a better discussion of the presence and absence of
+      --perms (including how it interacts with the new --executability and
+      --chmod options), an extended discussion of --temp-dir, an improved
+      discussion of --partial-dir, a better description of rsync's pattern
+      matching characters, an improved --no-implied-dirs section, and the
+      documenting of what the --stats option outputs.
+
+    - Various new and updated diffs in the patches dir, including: acls.diff,
+      xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
 
   INTERNAL:
 
-    - Rsync now calls setlocale(LC_CTYPE, "").  This enables isprint() to
-      better discern which filename characters need to be escaped in
-      messages (which should result in fewer escaped characters in some
-      locales).
+    - We now use sigaction() and sigprocmask() if possible, and fall back on
+      signal() if not.  Using sigprocmask() ensures that rsync enables all the
+      signals that it needs, just in case it was started in a masked state.
 
-    - Improved the naming of the log-file open/reopen/close functions.
+    - Some buffer sizes were expanded a bit, particularly on systems where
+      MAXPATHLEN is overly small (e.g. cygwin).
 
-    - Removed some protocol-compatibility code that was only needed to help
-      someone running a pre-release of 2.6.4.
+    - If io_printf() tries to format more data than fits in the buffer, exit
+      with an error instead of transmitting a truncated buffer.
 
-  BUILD CHANGES:
+    - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+      the VA_COPY macro.
 
-    - Added configure option "--disable-locale" to disable any use of
-      setlocale() in the binary.
+    - Reduced the amount of stack memory needed for each level of directory
+      recursion by nearly MAXPATHLEN bytes.
 
-    - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
-      rsync from being built without symlink or hard-link support.
+    - The wildmatch function was extended to allow an array of strings to be
+      supplied as the string to match.  This allows the exclude code to do less
+      string copying.
 
-    - Only #define HAVE_REMSH if it is going to be set to 1.
+    - Got rid of the safe_fname() function (and all the myriad calls) and
+      replaced it with a new function in the log.c code that filters all the
+      output going to the terminal.
 
-    - Configure now disables the use of mkstemp() under HP-UX (since they
-      refuse to fix its broken handling of large files).
+    - Unified the f_name() and the f_name_to() functions.
 
-    - Configure now explicitly checks for the lseek64() function so that
-      the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
-      presence based on the presence of the off64_t type.
+    - Improved the hash-table code the sender uses to handle checksums to make
+      it use slightly less memory and run just a little faster.
 
-    - Configure no longer mentions the change in the default remote-shell
-      (from rsh to ssh) that occurred for the 2.6.0 release.
+  DEVELOPER RELATED:
 
-    - Some minor enhancements to the test scripts.
+    - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
+      the previous -p0.  Also, the version included in the release tar now
+      affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
+      it is no longer necessary to run autoconf and/or yodl unless you're
+      applying a patch that was checked out from CVS.
 
-    - Added a few new *.diff files to the patches dir, including a patch
-      that enables the optional copying of extended attributes.
+    - Several diffs in the patches dir now use the proper --enable-FOO
+      configure option instead of --with-FOO to turn on the inclusion of
+      the newly patched feature.
+
+    - There is a new script, "prepare-source" than can be used to update the
+      various generated files (proto.h, configure, etc.) even before configure
+      has created the Makefile (this is mainly useful when patching the source
+      with a patch that doesn't affect generated files).
+
+    - The testsuite now sets HOME so that it won't be affected by a file such
+      as ~/.popt.

+NEWS for rsync 2.6.6 (28 Jul 2005)
+Protocol: 29 (unchanged)
+Changes since 2.6.5:
+
+  SECURITY FIXES:
+
+    - The zlib code was upgraded to version 1.2.3 in order to make it more
+      secure.  While the widely-publicized security problem in zlib 1.2.2 did
+      not affect rsync, another security problem surfaced that affects rsync's
+      zlib 1.1.4.
+
+  BUG FIXES:
+
+    - The setting of flist->high in clean_flist() was wrong for an empty list.
+      This could cause flist_find() to crash in certain rare circumstances
+      (e.g. if just the right directory setup was around when --fuzzy was
+      combined with --link-dest).
+
+    - The outputting of hard-linked files when verbosity was > 1 was not right:
+      (1) Without -i it would output the name of each hard-linked file as
+      though it had been changed; it now outputs a "is hard linked" message for
+      the file. (2) With -i it would output all dots for the unchanged
+      attributes of a hard-link; it now changes those dots to spaces, as is
+      done for other totally unchanged items.
+
+    - When backing up a changed symlink or device, get rid of any old backup
+      item so that we don't get an "already exists" error.
+
+    - A couple places that were comparing a local and a remote modification-
+      time were not honoring the --modify-window option.
+
+    - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
+      set too often (if some non-significant mode bits differed).
+
+    - Fixed a really old, minor bug that could cause rsync to warn about being
+      unable to mkdir() a path that ends in "/." because it just created the
+      directory (required --relative, --no-implied-dirs, a source path that
+      ended in either a trailing slash or a trailing "/.", and a non-existing
+      destination dir to tickle the bug in a recent version).
+
+  ENHANCEMENTS:
+
+    - Made the "max verbosity" setting in the rsyncd.conf file settable on a
+      per-module basis (which now matches the documentation).
+
+    - The support/rrsync script has been upgraded to verify the args of options
+      that take args (instead of rejecting any such options).  The script was
+      also changed to try to be more secure and to fix a problem in the parsing
+      of a pull operation that has multiple sources.
+
+    - Improved the documentation that explains the difference between a
+      normal daemon transfer and a daemon-over remote-shell transfer.
+
+    - Some of the diffs supplied in the patches dir were fixed and/or
+      improved.
+
+  BUILD CHANGES:
+
+    - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
+      NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
+      find in the /etc/group file).
+
+    - Added a test to the test suite, itemized.test, that tests the output of
+      -i (log-format w/%i) and some double-verbose messages.
+
+
+NEWS for rsync 2.6.5 (1 Jun 2005)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
+
+  OUTPUT CHANGES:
+
+    - Non-printable chars in filenames are now output using backslash-
+      escaped characters rather than '?'s.  Any non-printable character is
+      output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
+      is now output as "\\".  Rsync also uses your locale setting, which
+      can make it treat fewer high-bit characters as non-printable.
+
+    - If rsync received an empty file-list when pulling files, it would
+      output a "nothing to do" message and exit with a 0 (success) exit
+      status, even if the remote rsync returned an error (it did not do
+      this under the same conditions when pushing files).  This was changed
+      to make the pulling behavior the same as the pushing behavior:  we
+      now do the normal end-of-run outputting (depending on options) and
+      exit with the appropriate exit status.
+
+  BUG FIXES:
+
+    - A crash bug was fixed when a daemon had its "path" set to "/", did
+      not have chroot enabled, and used some anchored excludes in the
+      rsyncd.conf file.
+
+    - Fixed a bug in the transfer of a single file when -H is specified
+      (rsync would either infinite loop or perhaps crash).
+
+    - Fixed a case where the generator might try (and fail) to tweak the
+      write-permissions of a read-only directory in list-only mode (this
+      only caused an annoying warning message).
+
+    - If --compare-dest or --link-dest uses a locally-copied file as the
+      basis for an updated version, log this better when --verbose or -i
+      is in effect.
+
+    - Fixed the accidental disabling of --backup during the --delete-after
+      processing.
+
+    - Restored the ability to use the --address option in client mode (in
+      addition to its use in daemon mode).
+
+    - Make sure that some temporary progress information from the delete
+      processing does not get left on the screen when it is followed by a
+      newline.
+
+    - When --existing skips a directory with extra verbosity, refer to it
+      as a "directory", not a "file".
+
+    - When transferring a single file to a different-named file, any
+      generator messages that are source-file related no longer refer to
+      the file by the destination filename.
+
+    - Fixed a bug where hard-linking a group of files might fail if the
+      generator hasn't created a needed destination directory yet.
+
+    - Fixed a bug where a hard-linked group of files that is newly-linked
+      to a file in a --link-dest dir doesn't link the files from the rest
+      of the cluster.
+
+    - When deleting files with the --one-file-system (-x) option set, rsync
+      no longer tries to remove files from inside a mount-point on the
+      receiving side.  Also, we don't complain about being unable to remove
+      the mount-point dir.
+
+    - Fixed a compatibility problem when using --cvs-ignore (-C) and
+      sending files to an older rsync without using --delete.
+
+    - Make sure that a "- !" or "+ !" include/exclude pattern does not
+      trigger the list-clearing action that is reserved for "!".
+
+    - Avoid a timeout in the generator when the sender/receiver aren't
+      handling the generator's checksum output quickly enough.
+
+    - Fixed the omission of some directories in the delete processing when
+      --relative (-R) was combined with a source path that had a trailing
+      slash.
+
+    - Fixed a case where rsync would erroneously delete some files and then
+      re-transfer them when the options --relative (-R) and --recursive
+      (-r) were both enabled (along with --delete) and a source path had a
+      trailing slash.
+
+    - Make sure that --max-size doesn't affect a device or a symlink.
+
+    - Make sure that a system with a really small MAXPATHLEN does not cause
+      the buffers in readfd_unbuffered() to be too small to receive normal
+      messages.  (This mainly affected Cygwin.)
+
+    - If a source pathname ends with a filename of "..", treat it as if
+      "../" had been specified (so that we don't copy files to the parent
+      dir of the destination).
+
+    - If --delete is combined with a file-listing rsync command (i.e. no
+      transfer is happening), avoid outputting a warning that we couldn't
+      delete anything.
+
+    - If --stats is specified with --delete-after, ensure that all the
+      "deleting" messages are output before the statistics.
+
+    - Improved one "if" in the deletion code that was only checking errno
+      for ENOTEMPTY when it should have also been checking for EEXIST (for
+      compatibility with OS variations).
+
+  ENHANCEMENTS:
+
+    - Added the --only-write-batch=FILE option that may be used (instead
+      of --write-batch=FILE) to create a batch file without doing any
+      actual updating of the destination.  This allows you to divert all
+      the file-updating data away from a slow data link (as long as you
+      are pushing the data to the remote server when creating the batch).
+
+    - When the generator is taking a long time to fill up its output buffer
+      (e.g. if the transferred files are few, small, or missing), it now
+      periodically flushes the output buffer so that the sender/receiver
+      can get started on the files sooner rather than later.
+
+    - Improved the keep-alive code to handle a long silence between the
+      sender and the receiver that can occur when the sender is receiving
+      the checksum data for a large file.
+
+    - Improved the auth-errors that are logged by the daemon to include
+      some information on why the authorization failed:  wrong user,
+      password mismatch, etc.  (The client-visible message is unchanged!)
+
+    - Improved the client's handling of an "@ERROR" from a daemon so that
+      it does not complain about an unexpectedly closed socket (since we
+      really did expect the socket to close).
+
+    - If the daemon can't open the log-file specified in rsyncd.conf, fall
+      back to using syslog and log an appropriate warning.  This is better
+      than what was typically a totally silent (and fatal) failure (since a
+      daemon is not usually run with the --no-detach option that was
+      necessary to see the error on stderr).
+
+    - The man pages now consistently refer to an rsync daemon as a "daemon"
+      instead of a "server" (to distinguish it from the server process in a
+      non-daemon transfer).
+
+    - Made a small change to the rrsync script (restricted rsync -- in the
+      support dir) to make a read-only server reject all --remove-* options
+      when sending files (to future-proof it against the possibility of
+      other similar options being added at some point).
+
+  INTERNAL:
+
+    - Rsync now calls setlocale(LC_CTYPE, "").  This enables isprint() to
+      better discern which filename characters need to be escaped in
+      messages (which should result in fewer escaped characters in some
+      locales).
+
+    - Improved the naming of the log-file open/reopen/close functions.
+
+    - Removed some protocol-compatibility code that was only needed to help
+      someone running a pre-release of 2.6.4.
+
+  BUILD CHANGES:
+
+    - Added configure option "--disable-locale" to disable any use of
+      setlocale() in the binary.
+
+    - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented

+
+    - Only #define HAVE_REMSH if it is going to be set to 1.

-manpagesection(RUNNING AN RSYNC DAEMON OVER A REMOTE SHELL PROGRAM)
-
-If rsync is run with both the bf(--daemon) and bf(--rsh) (bf(-e)) options, it will
-spawn an rsync daemon using a remote shell connection.  Several
-configuration options will not be available unless the remote user is
-root (e.g. chroot, setuid/setgid, etc.).  There is no need to configure
-inetd or the services map to include the rsync daemon port if you run an
-rsync daemon only via a remote shell program.
-
-ADVANCED: To run an rsync daemon out of a single-use ssh key, use the
-"command=em(COMMAND)" syntax in the remote user's authorized_keys entry,
-where command would be
-
-quote(tt(rsync --server --daemon .))
-
-NOTE: rsync's argument parsing expects the trailing ".", so make sure
-that it's there.  If you want to use an rsyncd.conf(5)-style
-configuration file other than the default, you can added a
-bf(--config) option to the em(command):
-
-quote(tt(rsync --server --daemon --config=em(file) .))
-
-Note that the "--server" here is the internal option that rsync uses to
-run the remote version of rsync that it communicates with, and thus you
-should not be using the bf(--server) option under normal circumstances.

-example of the library is given in the file example.c which also tests that
-the library is working correctly. Another example is given in the file

-The changes made in version 1.1.4 are documented in the file ChangeLog.
-The only changes made since 1.1.3 are bug corrections:
-
-- ZFREE was repeated on same allocation on some error conditions.
-  This creates a security problem described in
-  http://www.zlib.org/advisory-2002-03-11.txt
-- Returned incorrect error (Z_MEM_ERROR) on some invalid data
-- Avoid accesses before window for invalid distances with inflate window
-  less than 32K.
-- force windowBits > 8 to avoid a bug in the encoder for a window size
-  of 256 bytes. (A complete fix will be available in 1.1.5).
-
-The beta version 1.1.5beta includes many more changes. A new official
-version 1.1.5 will be released as soon as extensive testing has been
-completed on it.

 Notes for some targets:
 
-- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
-  and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
-  The zlib DLL support was initially done by Alessandro Iacopetti and is
-  now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
-  home page at http://www.winimage.com/zLibDll
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
 
-  From Visual Basic, you can call the DLL functions which do not take
-  a structure as argument: compress, uncompress and all gz* functions.
-  See contrib/visual-basic.txt for more information, or get
-  http://www.tcfb.com/dowseware/cmp-z-it.zip
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+  compiler flag). The compiler bug has been reported to SGI.

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.
