+version 1.19.90 (CVS)
+
+* New option --auto-compress (-a)
+
+With --create, selects compression algorithm basing on the suffix
+of the archive file name.
+
+* New option --lzma
+
+Selects LZMA compression algorithm
+
+* New option --hard-dereference
+
+During archive creation, dereferences hard links and stores the files
+they refer to, instead of creating usual hard link members (type '1').
+
+* New option --checkpoint-action
+
+This action allows to specify an action to be executed upon hitting a
+checkpoint.  Recognized actions are: dot, echo (the default),
+echo=string, ttyout=string, exec=cmdline, and sleep=value.  Any number
+of `--checkpoint-action' options can be specified, the actions will be
+executed in order of their appearance in the command line.  See
+chapter 3.8 "Checkpoints" for a complete description.
+
+* New options --no-check-device, --check-device.
+
+The `--no-check-device' option disables comparing device numbers during
+preparatory stage of an incremental dump.  This allows to avoid
+creating full dumps if the device numbers change (e.g. when using an
+LVM snapshot).
+
+The `--check-device' option enables comparing device numbers.  This is
+the default.  This option is provided to undo the effect of the previous
+`--no-check-device' option, e.g. if it was set in TAR_OPTIONS
+environment variable.
+
+* The --transform option.
+
+Any number of `--transform' options can be given in the command line.
+The specified transformations will be applied in turn.
+
+The argument to `--transform' option can be a list of replace
+expressions, separated by a semicolon (as in `sed').
+
+Filename transformations are applied to symbolic link targets
+during both creation and extraction.  Tar 1.19 used them only
+during extraction.
+
+For a detailed description, see chapter 6.7 "Modifying File and Member
+Names". 
+
+* Info (end-of-volume) scripts
+
+The value of the blocking factor is made available to info and
+checkpoint scripts via environment variable TAR_BLOCKING_FACTOR.
+
+* Bugfixes.
+** Fix bug introduced in version 1.19: tar refused to update non-existing
+archives.

+@section Checkpoints
+@cindex checkpoints, defined
+@opindex checkpoint
+@opindex checkpoint-action
+
+A @dfn{checkpoint} is a moment of time before writing @var{n}th record to
+the archive (a @dfn{write checkpoint}), or before reading @var{n}th record
+from the archive (a @dfn{read checkpoint}).  Checkpoints allow to
+periodically execute arbitrary actions.
+
+The checkpoint facility is enabled using the following option:
+
+@table @option
+@xopindex{checkpoint, defined}
+@item --checkpoint[=@var{n}]
+Schedule checkpoints before writing or reading each @var{n}th record.
+The default value for @var{n} is 10.
+@end table
+
+A list of arbitrary @dfn{actions} can be executed at each checkpoint.
+These actions include: pausing, displaying textual messages, and
+executing arbitrary external programs.  Actions are defined using
+the @option{--checkpoint-action} option.
+
+@table @option
+@xopindex{checkpoint-action, defined}
+@item --checkpoint-action=@var{action}
+Execute an @var{action} at each checkpoint.
+@end table
+
+@cindex @code{echo}, checkpoint action
+The simplest value of @var{action} is @samp{echo}.  It instructs
+@command{tar} to display the default message on the standard error
+stream upon arriving at each checkpoint.  The default message is (in
+@acronym{POSIX} locale) @samp{Write checkpoint @var{n}}, for write
+checkpoints, and @samp{Read checkpoint @var{n}}, for read checkpoints.
+Here, @var{n} represents ordinal number of the checkpoint.
+
+In another locales, translated versions of this message are used.
+
+This is the default action, so running:
+
+@smallexample
+$ @kbd{tar -c --checkpoint=1000 --checkpoint-action=echo} /var
+@end smallexample
+
+@noindent
+is equivalent to:
+
+@smallexample
+$ @kbd{tar -c --checkpoint=1000} /var
+@end smallexample
+
+The @samp{echo} action also allows to supply a customized message.
+You do so by placing an equals sign and the message right after it,
+e.g.:
+
+@smallexample
+--checkpoint-action="echo=Hit %s checkpoint #%u"
+@end smallexample
+
+The @samp{%s} and @samp{%u} in the above example are
+@dfn{meta-characters}.  The @samp{%s} meta-character is replaced with
+the @dfn{type} of the checkpoint: @samp{write} or
+@samp{read} (or a corresponding translated version in locales other
+than @acronym{POSIX}).  The @samp{%u} meta-character is replaced with
+the ordinal number of the checkpoint.  Thus, the above example could
+produce the following output when used with the @option{--create}
+option:
+
+@smallexample
+tar: Hit write checkpoint #10
+tar: Hit write checkpoint #20
+tar: Hit write checkpoint #30
+@end smallexample
+
+Aside from meta-character expansion, the message string is subject to
+@dfn{unquoting}, during which the backslash @dfn{escape sequences} are
+replaced with their corresponding @acronym{ASCII} characters
+(@pxref{escape sequences}).  E.g. the following action will produce an
+audible bell and the message described above at each checkpoint:
+
+@smallexample
+--checkpoint-action='echo=\aHit %s checkpoint #%u'
+@end smallexample
+
+@cindex @code{bell}, checkpoint action
+There is also a special action which produces an audible signal:
+@samp{bell}.  It is not equivalent to @samp{echo='\a'}, because
+@samp{bell} sends the bell directly to the console (@file{/dev/tty}),
+whereas @samp{echo='\a'} sends it to the standard error.
+
+@cindex @code{ttyout}, checkpoint action
+The @samp{ttyout=@var{string}} action outputs @var{string} to
+@file{/dev/tty}, so it can be used even if the standard output is
+redirected elsewhere.  The @var{string} is subject to the same
+modifications as with @samp{echo} action.  In contrast to the latter,
+@samp{ttyout} does not prepend @command{tar} executable name to the
+string, nor does it output a newline after it.  For example, the
+following action will print the checkpoint message at the same screen
+line, overwriting any previous message:
+
+@smallexample
+--checkpoint-action="ttyout=\rHit %s checkpoint #%u"
+@end smallexample
+
+@cindex @code{dot}, checkpoint action
+Another available checkpoint action is @samp{dot} (or @samp{.}).  It
+instructs @command{tar} to print a single dot on the standard listing
+stream, e.g.:
+
+@smallexample
+$ @kbd{tar -c --checkpoint=1000 --checkpoint-action=dot} /var
+...
+@end smallexample
+
+For compatibility with previous @GNUTAR{} versions, this action can
+be abbreviated by placing a dot in front of the checkpoint frequency,

+
+Any number of actions can be defined, by supplying several

+example, the command below displays two messages, pauses
+execution for 30 seconds and executes the @file{/sbin/cpoint} script:
+
+@example

+       --checkpoint-action='exec=/sbin/cpoint'}

+This example also illustrates the fact that
+@option{--checkpoint-action} can be used without

+@cindex File names, using hard links
+@cindex hard links, dereferencing
+@cindex dereferencing hard links
+
+Normally, when @command{tar} archives a hard link, it writes a
+block to the archive naming the target of the link (a @samp{1} type
+block).  In that way, the actual file contents is stored in file only
+once.  For example, consider the following two files:
+
+@smallexample
+@group
+$ ls
+-rw-r--r--   2 gray staff       4 2007-10-30 15:11 one
+-rw-r--r--   2 gray staff       4 2007-10-30 15:11 jeden
+@end group
+@end smallexample
+
+Here, @file{jeden} is a link to @file{one}.  When archiving this
+directory with a verbose level 2, you will get an output similar to
+the following:
+
+@smallexample
+$ tar cfvv ../archive.tar .
+drwxr-xr-x gray/staff        0 2007-10-30 15:13 ./
+-rw-r--r-- gray/staff        4 2007-10-30 15:11 ./jeden
+hrw-r--r-- gray/staff        0 2007-10-30 15:11 ./one link to ./jeden
+@end smallexample
+
+The last line shows that, instead of storing two copies of the file,
+@command{tar} stored it only once, under the name @file{jeden}, and
+stored file @file{one} as a hard link to this file.
+
+It may be important to know that all hard links to the given file are
+stored in the archive.  For example, this may be necessary for exact
+reproduction of the file system.  The following option does that:
+
+@table @option
+@xopindex{check-links, described}
+@item --check-links
+@itemx -l
+Check the number of links dumped for each processed file.  If this
+number does not match the total number of hard links for the file, print
+a warning message.
+@end table
+
+For example, trying to archive only file @file{jeden} with this option
+produces the following diagnostics:
+
+@smallexample
+$ tar -c -f ../archive.tar jeden
+tar: Missing links to `jeden'.
+@end smallexample
+
+Although creating special records for hard links helps keep a faithful
+record of the file system contents and makes archives more compact, it
+may present some difficulties when extracting individual members from
+the archive.  For example, trying to extract file @file{one} from the
+archive created in previous examples produces, in the absense of file
+@file{jeden}:
+
+@smallexample
+$ tar xf archive.tar ./one
+tar: ./one: Cannot hard link to `./jeden': No such file or directory
+tar: Error exit delayed from previous errors
+@end smallexample
+
+The reason for this behavior is that @command{tar} cannot seek back in
+the archive to the previous member (in this case, @file{one}), to
+extract it@footnote{There are plans to fix this in future releases.}.
+If you wish to avoid such problems at the cost of a bigger archive,
+use the following option:
+
+@table @option
+@xopindex{hard-dereference, described}
+@item --hard-dereference
+Dereference hard links and store the files they refer to.
+@end table
+
+For example, trying this option on our two sample files, we get two
+copies in the archive, each of which can then be extracted
+independently of the other:
+
+@smallexample
+@group
+$ tar -c -vv -f ../archive.tar --hard-dereference .
+drwxr-xr-x gray/staff        0 2007-10-30 15:13 ./
