 Oooops ... I forgot to test on the Zaurus 5500 ...
 
 Fixed many problems of new (english) strings (and german translations)
 introduced in the latest versions, where the text was not fitting on the 
 240x320 display of the Zaurus 5500.
 
+KO/Pi:
 Added a popup menu ( press pen and hold to get popup ) to the agenda view
 with many useful items (add event/todo, show next week, two weeks, month, journal).
 
 Added items to the todolist popup menu for:
 Display all opened, all closed or all todos flat.
 The "flat" view makes is possible to sort all todos after ,e.g., prio or date.
@@ -25,12 +26,18 @@ Fixed behaviour of automatic setting completion of todos with sub-todos/parent t
 Now the behaviour is:
 Setting a parent to complete  sets all (sub)childs to complete. 
 Setting a parent to uncomplete does not change the childs.
 Setting a child to uncomplete sets all parent to uncomplete.
 Setting a child to complete does not change the parents.
 
+Smart updating and double buffering of the daymatrix.
+Showing holidays in the day matrix.
+Many other small performance updates.
+
+Made day labels in agenda clickable. By clicking a label, the day is displayed in single day mode.
+
 Now the translation file usertranslation.txt is supposed to be in utf8 format.
 If you want to translate a language from western europe, just change the germantranslation.txt file. Please read the updated Usertranslation HowTo in KO/Pi Help menu.
