-version 1.16.2
+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.

+version 1.19 - Sergey Poznyakoff, 2007-10-10
+
+* New option --exclude-vcs
+
+Excludes directories and files, created by several widely used version
+control systems, e.g. "CVS/", ".svn/", etc.
+
+* --exclude-tag and --exclude-cache options
+
+The following options now work with incremental archives as well:
+
+ --exclude-caches
+ --exclude-caches-all
+ --exclude-tag
+ --exclude-tag-all
+ --exclude-tag-under
+
+* Fix handling of renamed files in listed incremental archives.
+
+Previous versions always stored absolute file names in rename
+records, even if -P was not used. This is fixed: rename records
+contain file names processed in accordance with the command line
+settings.
+
+* Fix --version output.
+
+* Recognition of broken archives.
+
+When supplied an archive smaller than 512 bytes in reading mode (-x,
+-t), the previous version of tar silently ignored it, exiting with
+code 0. It is fixed. Tar now issues the following diagnostic message:
+'This does not look like a tar archive', and exits with code 2.
+
+* Fix double-dot recognition in archive member names in case of duplicate '/.'.
+
+* Fix file padding in case of truncation of the input file to zero size.
+

+version 1.18 - Sergey Poznyakoff, 2007-06-29
+
+* Licensed under the GPLv3
+
+* Fixed several bugs in the testsuite
+
+\f
+version 1.17 - Sergey Poznyakoff, 2007-06-08
* Fix archivation of sparse files in posix mode. Previous versions padded
sparse members with spurious zero blocks.
-
+
* Fix operation of --verify --listed-incremental. Version 1.16.1 produced
a full dump when both options were given.
-* Fix --occurence. In previous versions it continued scanning the archive
+* Fix --occurrence. In previous versions it continued scanning the archive
even though all requested members has already been extracted.
-* The options --transform and --strip-components affect hard and soft link
- targets.
+* Scope of --transform and --strip-components options.
+
+In addition to affecting regular archive members, the --transform
+option affects hard and soft link targets and the --strip-components
+option affects hard link targets as well.
* End-of-volume script can send the new volume name to tar by writing
- it to the file descriptor $TAR_FD.
-
+ it to the file descriptor stored in the environment variable `TAR_FD'.
