Changes in dtrx
===============

Version 6.1
-----------

New features
~~~~~~~~~~~~

 * Add support for InstallShield archives, using the unshield command.

 * The wording of many of the interactive prompts has been adjusted,
   hopefully to be clearer and provide more information to the user
   immediately.

Bug fixes
~~~~~~~~~

 * dtrx 6.1 does a better job protecting against race conditions when
   extracting a single file.

 * If you used the -f option, and extracted an archive that only contained
   one file or directory, dtrx 6.0 would still prompt you to ask how it
   should be extracted.  dtrx 6.1 fixes this, extracting the contents to
   the current directory as -f requires.

 * Recursive extraction would not work well in dtrx 6.0 when the contents
   of the original archive were a single file.  This has been fixed in dtrx
   6.1.

Version 6.0
-----------

New features
~~~~~~~~~~~~

 * When you specify -v at the command line, dtrx will display the files it
   extracts, much like tar.

 * When dtrx prompts you about how to handle recursive archives, you now
   have the option of listing what those archives before making a decision.

 * dtrx will now provide more information about why a particular extraction
   attempt failed.  It will show you error messages from all the attempts
   it made, rather than only the last error it got.  It will also detect
   and warn you when one of the underlying extraction tools, like
   cabextract, cannot be found.

 * dtrx does a better job of cleaning up after itself.  It wouldn't always
   clean up temporary files after certain errors; that has been fixed.  It
   also catches SIGINT and SIGTERM and cleans up before finishing
   execution.

Bug fixes
~~~~~~~~~

 * Version 5.0 introduced a regression such that dtrx would not offer to
   extract recursive archives that were hidden under subdirectories.
   Version 6.0 fixes that.

 * dtrx would not properly extract recursive archives when the original
   archive contained a single directory.  This has been fixed.

Version 5.1
-----------

Bug fixes
~~~~~~~~~

 * Version 5.0 did not work with Python 2.3; it used a new language
   feature.  This release fixes that.

Version 5.0
-----------

New features
~~~~~~~~~~~~

 * dtrx can now extract Ruby gems, 7z archives, and Microsoft Cabinet
   archives.  It can also handle files compressed with lzma, and extract
   the metadata from Debian packages and Ruby gems.

 * dtrx will now use several strategies to try to figure out what kind of
   file you have, and extract it accordingly.  If one doesn't work, it'll
   try something else if it can.

 * dtrx now displays more helpful errors when things go wrong.

 * Previous versions of dtrx would look at what files were included in an
   archive, and then make a decision about how to extract it.  Now, it
   always extracts files to a temporary directory, and figures out what to
   do with that directory afterward.  This should be slightly faster and
   nicer to the system.

Version 4.0
-----------

New features
~~~~~~~~~~~~

 * dtrx is now interactive.  If the archive only contains one item, or
   contains other archives, dtrx will ask you how you would like to handle
   it.  You can turn these questions off the the -n option.

 * There is a new -l option, which simply lists the archive's contents
   rather than extracting them.
