   do this any more (thanks to Oliver Endriss for pointing this out).

 - Moved several menu item classes from menu.c to menuitems.[hc] to make them
   available for plugins.
 - The epg2html.pl script now handles '|' in description texts.
+- The new setup option "OSD/Use small font" can be used to control the use of
+  the small font (see MANUAL for details).
+- Swapped osd.[hc] and osdbase.[hc] to have the virtual OSD base class named cOsd.
+  Plugins may need to adjust their #include statements.
+- Colors are now given as AARRGGBB instead of AABBGGRR. The values are mapped to
+  the driver's (wrong) sequence in dvbosd.c (this should really be fixed in the
+  driver, together with the endian problem).
+- The new OSD setup parameters "Left" and "Top" can be used to define the top left
+  corner of the OSD.
+- The OSD size prameters are now in pixel (as opposed to formerly characters).
+  When reading a 'setup.conf' file from an older version of VDR, the OSDwidth
+  and OSDheight values will be converted to pixel automatically.
+- The OSD is now fully device independent. See the comments in VDR/osd.h and the
+  description in PLUGINS.html for information on how a plugin can implement an OSD
+  display on arbitrary hardware.
+- The OSD (actually its cBitmap class) can now handle XPM files. There are several
+  XPM files in the VDR/symbols directory which can be used by skins (some of these
+  have been taken from the "elchi" patch). See VDR/skinsttng.c for examples on how
+  to use these.
+- Due to the changes in the OSD handling the DEBUG_OSD option for a textual OSD
+  has been dropped. There will be a plugin that implements a skin with this
+  functionality later.
+- The entire OSD display can now be implemented via "skins". See VDR/skins.[hc],
+  VDR/skinclassic.[hc], VDR/skinsttng.[hc] and PLUGINS.html for information on how
+  a plugin can implement its own skin. By default VDR comes with a "Classic" skin
+  that implements the OSD display known from previous versions, and the new skin
+  named "ST:TNG Panels", which is also the default skin now. The actual skin can
+  be selected through "Setup/OSD/Skin".
+- The colors used in a skin can now be configured using "themes". See PLUGINS.html
+  for information on how a skin can make use of themes, and man vdr(5) for the
+  structure of a theme file. The actual theme to use can be selected through
+  "Setup/OSD/Theme".
