-version 1.23.90 - (Git)
+version ?.? - ?, 201?-??-??
+
+* New features
+
+** --owner and --group names and numbers
+
+The --owner and --group options now accept operands of the form
+NAME:NUM, so that you can specify both symbolic name and numeric ID
+for owner and group.  In these options, NAME no longer needs to be
+present in the current host's user and group databases.
+
+version 1.26 - Sergey Poznyakoff, 2011-03-12
+
+* Bugfixes
+
+** Fix the --verify option, which broke in version 1.24.
+
+** Fix storing long sparse file names in PAX archives.
+
+** Fix correctness of --atime-preserve=replace
+
+tar --atime-preserve=replace no longer tries to restore atime of
+zero-sized files.
+
+** Work around POSIX incompatibilities on FreeBSD, NetBSD and Tru64
+
+** Fix bug with --one-file-system --listed-incremental
+
+When invoked with these two options, tar 1.25 would add only the
+top-level directory to the archive, but not its contents.

+version 1.25 - Sergey Poznyakoff, 2010-11-07
+
+* Fix extraction of empty directories with the -C option in effect.
+* Fix extraction of device nodes.
+* Make sure name matching occurs before eventual name transformation.
+
+Tar 1.24 changed the ordering of name matching and name transformation
+so that the former saw already transformed file names.  This made it
+impossible to match file names in certain cases.  It is fixed now.
+
+* Fix the behavior of tar -x --overwrite on hosts lacking O_NOFOLLOW.
+
+* Improve the testsuite.
+
+* Alternative decompression programs.
+
+If extraction from a compressed archive fails because the corresponding
+compression program is not installed and the following two conditions
+are met, tar retries extraction using an alternative decompressor:
+
+ 1. Another compression program supported by tar is able to handle this
+ compression format.
+ 2. The compression program was not explicitly requested in the command
+ line by the use of such options as -z, -j, etc.
+
+For example, if `compress' is not available, tar will try `gzip'.

+** Symbolic link attributes
+
+When extracting symbolic links, tar now restores attributes such as
+last-modified time and link permissions, if the operating system
+supports this.  For example, recent versions of the Linux kernel
+support setting times on symlinks, and some BSD kernels also support
+symlink permissions.
+
+** --dereference consistency
+
+The --dereference (-h) option now applies to files that are copied
+into or out of archives, independently of other options.  For example,
+if F is a symbolic link and archive.tar contains a regular-file member
+also named F, "tar --overwrite -x -f archive.tar F" now overwrites F
+itself, rather than the file that F points to.  (To overwrite the file
+that F points to, add the --dereference (-h) option.)  Formerly,
+--dereference was intended to apply only when using the -c option, but
+the implementation was not consistent.
+
+Also, the --dereference option no longer affects accesses to other
+files, such as archives and time stamp files.  Symbolic links to these
+files are always followed.  Previously, the links were usually but not
+always followed.
