 Info about the changes in new versions of KDE-Pim/Pi
 
 ********** VERSION 2.1.13 ************
 
 Fixed a problem in KA/Pi search.
 Fixed some minor problems in KO/Pi.
-Added calendar selection possibility to the todo view popup and to the event/todo editor.

+Added calendar selection possibility to the todo view popup and to the event/todo/journal editor.
+
+Fixed memory usage problems in KA/Pi:
+When loading data KA/Pi did load the file data twice.
+Example:
+  A 600k file did consume 1200k memory during loading process.
+  This is fixed, it does now consume only  600k during loading process.
+When saving data KA/Pi did consume a lot of memory for the data parsing during the save process.
+This is fixed.
+Example:
+  Before saving a 600k file KA/Pi did consume 21.7 Meg of Ram.
+  When saving  KA/Pi did consume 28.6 Meg of Ram. That causes a crash on the Zaurus because there was no memeory left in the system.
+  Now  KA/Pi is consuming on saving the same data 22.0 Meg of Ram during the save process. 
+Note: The memory usage of KA/Pi after the data is loaded/saved has not changed.
+
+Fixed memory usage problems in KO/Pi:
+When KO/Pi did save the data to file, it did not release the used buffers after saving.
+The used buffer was released after saving the next time, but there was new buffer space allocated again on that save operation.
+This is fixed.
+Example:
+  When saving a 400k file KO/Pi do now use 400k less memory now.
+
+Optimized memory usage in KO/Pi Agenda view:
+KO/Pi is storing some paint information in extra buffers for faster repainting of the agenda view.
+These buffers were not made smaller (i.e. downsized)  because of performance reasons.
+The handling of these buffers are now much smarter:
+Two (of six) buffers are removed completely.
+The remaing four buffers are now downsized after not using the agenda view for 45 seconds.
+Such that the memory usage of KO/Pi is smaller now in general ( because 2 buffers are removed) and is much smaller when not using the agenda view. That is very important when using fastload for KO/Pi.
+
+Worst case example ( for a maximum size agenda content):
+  When resizing the agenda content to a large scale, KO/Pi did use 17Meg of mem ( and did not use less memory until it was stopped). Now KO/Pi is using on the same operation only 14.3 Meg of mem and after 45 seconds not using the agenda view it uses only 9.4 Meg of mem.
+
+Summary:
+Many memory wasting problems of KA/Pi and KO/Pi fixed such that it is better to use on the Zaurus.
 
 ********** VERSION 2.1.12 ************
 
 KO/Pi:
 Many small usability fixes, e.g. rearranged the popup menus such that they are better to use on the Zaurus.
 Fixed a problem with the month view when file was saved but KO/Pi was not the active window.
