+- Internationalization is now done with 'gettext' (following a suggestion by
+  Lucian Muresan). Plugin authors may want to use the Perl script
+  'i18n-to-gettext.pl' to convert their internationalized texts to the gettext
+  format (see the instructions inside that script file). The function
+  cPlugin::RegisterI18n() is still present for compatibility, but doesn't
+  have any more functionality. So plugins that don't convert their texts to
+  the gettext format will only present English texts.
+  See PLUGINS.html, section "Internationalization", for instructions on how
+  to make strings in arrays translatable.
+  See README.i18n for information on how to create new or maintain existing
+  translations.
+- The 'newplugin' script has been extended to generate the Makefile section
+  for i18n support.
+- The parameter OSDLanguage in 'setup.conf' is now a string and holds the locale
+  code of the selcted OSD language (e.g. en_US). Therefore, when you first run
+  this version of VDR you may have to select your desired OSD language again.
