Overview of Changes from mdh-1.9.58 to mdh-1.9.59
=================================================
* Scratch-Pad settings and text buffers will now be saved between
  sessions and can be disabled by using the hidden scratch_pad.save 
  pref. Text buffers are saved in ~/.cache/mdh.
* Fixed a few GCC 4 errors and warnings.
* Fixed non-threaded panel operations.

Overview of Changes from mdh-1.9.57 to mdh-1.9.58
=================================================
* Added a simple audio (OSS) mixer. The toolbar button displays a
  master volume control only, use the main menu item for something
  a bit more functional. The mixer device can be configured using
  the hidden mixer.device pref.
* Button & custom button relief style and panel shadow type are now
  both configurable.
* The run xterm configuration has been removed from the main ui, but
  is still configurable using the run.xterm pref.
* Added NetWM support, detected by default. This may be a bit touchy,
  so forcibly disable (--disable-netwm) or enable (--enable-netwm) if
  you are having problems or seeing odd wm-related behavior. Some
  window managers may be a bit more cooperative if the toolbar is
  created with the DOCK window hint, set toolbar.use_dock to TRUE.
* Added Gnome support, detected by default.
* Move run history and temperature cache from ~/.config to ~/.cache
  ($XDG_CACHE_HOME).
* Major reorganization and cleanups.
* Relicensed as GPL.

Overview of Changes from mdh-1.9.56 to mdh-1.9.57
=================================================
* Panel functions now execute in their own thread to avoid
  interrupting other operations, but this has increased the overall
  memory usage quite a bit. Disable with --disable-threads.
* Added 3 custom panels which will display the output from a
  specified script or command. The output will be passed through
  gtk_label_set_markup() if pango_parse_markup() succeeds, otherwise
  the error will be logged and the original output will be shown.
  Certain characters are reserved and should be encoded if they are
  to be interpreted literally (s/</&lt;/, s/>/&gt;/). See
  http://developer.gnome.org/doc/API/2.0/pango/PangoMarkupFormat.html
  for details.
* Added support for libgtop-2.0 (2.6.0+). This is optional, but now
  the primary method of gathering system data. If you want to avoid
  use of gtop, disable with --disable-gtop.
* Added configurable display formats for all panels.
* Bolding thresholds for mail, cpu, mem and disk panels are now
  configurable. Mail: 1-N messages and Cpu, Mem, Disk: 1-100%.
* The weather panel's unit (standard, metric) can be configured
  through a hidden pref ('unit'), the default is standard. This
  will likely remain hidden to avoid confusion due to caching.
* An icon can now be assigned to custom buttons, an empty selection
  (or 'icon' pref) will disable the icon. The button name is no
  longer required, should you want only the icon to be visible.
* A city search is now builtin to help find your weather location id.
* Multi-panel counts are now configurable through the 'count' pref
  under the [panel_*] sections. See mdh_panel_*.h for ranges.
* Custom buttons can now be fully managed, additions and deletions 
  can be done in the ui.
* Defaults for custom buttons are only used if there is no existing
  configuration or saved values are missing.
* Many internal changes and cleanups.

Overview of Changes from mdh-1.9.55 to mdh-1.9.56
=================================================
* Moved from libconfuse to gini for configuration.
* The temperature panel has been rewritten to use weather.com's xml
  data instead of weather.noaa.gov. Existing configuration must be
  updated to use your zip code, rather than noaa.gov's station-id.
* An icon for the current weather conditions will be displayed in
  the temperature panel. The smallest Weather.com provides is 32x32,
  but that's a bit big, converted to 16x16, hope that's ok. :P

Overview of Changes from mdh-1.9.54 to mdh-1.9.55
=================================================
* GTK+ 2.4 is now required. Migrated GtkCombo to GtkComboBox and
  GtkItemFactory to GtkUIManager.
* Memory and network support for Net, Free, and OpenBSD (untested),
  thanks libstatgrab.
* Minor code cleanups.
