          http://packages.debian.org/search?keywords=libguestfs

        - O_CLOEXEC / SOCK_CLOEXEC is now used for almost all file
          descriptors that the library opens.

        - the daemon now has a growable strings buffer type (DECLARE_STRINGSBUF)

        - the <guestfs.h> header file works with C++ and we have a regression
          test for this

          give an error if they are not

        - .gitignore fixed to use absolute paths

          events to gobject signals (thanks Matt Booth)

        - bmptopng, wrestool (etc) missing or failure no longer prints
          warning messages

        - ruby: Use RbConfig instead of Config.

        - PYTHONPATH is set by the ./run script.

        - appliance building is now thread-safe.

        - appliance now uses 'ip' instead of 'ifconfig' and 'netstat'
          commands

        - several fixes to make parallel builds work properly

        - guestfish --listen now cleans up properly

        - the BUSY state has been removed
