2.8.0.2 stuff:

- GDM now supports more dynamic configuration.  The
  gdm daemon supports the --config option which allows
  an alternative configuration file to be supported. 
  The --with-configdir configure option may also be
  used to specify a system-wide configuration location
  so the gdm.conf file can be located on a mounted
  directory.  To support machine-specific configuration,
  an existing %sysconfdir/gdm configuration file will
  override a system-wide configuration file.  Refer
  to the GDM documentation for more information.

- New configuration option AlwaysLoginCurrentSession
  which will automatically switch the user to their
  previous session without asking.  This feature is
  turned off by default. (William Jon McCann)

- Now Use24Clock setting support "auto" which will
  use the system default for date/time formatting.
  (Tommi Vainikainen)

- Better backwards compatibility support for Welcome
  and RemoteWelcome.  If using an old gdm.conf file
  that does not have settings for DefaultWelcome and/or
  DefaultRemoteWelcome, GDM will continue to work as
  it did before these new configuration options were
  added.  (Brian Cameron)

- Usability improvements to gdmsetup.  "Face Browser"
  tab renamed to "User".  Now tabs no longer have
  mnemonics, since this violates HIG.  Fixed broken
  sensitivity on the "Users" tab.  Improved labels.

- Support HIG style button layout in gdmlogin.
  (William Jon McCann)

- Use GTK+ themed icon stock_person before falling
  back to the DefaultFace.  (William Jon McCann)

- Usability improvements to the face browser when using
  gdmgreeter, now the background behind the userlist
  translucent.  (William Jon McCann)

- Usability improvements to gdmphotosetup, and now 
  better follows HIG.   (William Jon McCann)

- New selection of face browser images.  (William
  Jon McCann) 

- No longer stat or read face images from remote home
  directories.  (William Jon McCann)

- New gdmflexiserver command "GET_CONFIG_FILE" which
  will return the location of the configuration file
  being used by the daemon.  (Brian Cameron)

- Now gdmflexiserver command "GET_CONFIG" works.
  Previously it only returned a value if the value
  was set in the gdm.conf file.  Now it returns
  compiled-in default values if gdm.conf has no
  setting.  (Brian Cameron)

- Support DragonFly VT. (Joerg Sonnenberger)

- GDM configure script now Supports TCP Wrappers on Solaris.
  (Brian Cameron)

- Many string/grammar improvements. (Tommi Vainikainen,
  Brian Cameron)

- Better C89 compiler support.  (Jens Granseuer)
