+- wxCondition now must be used with a mutex, please read the (updated) class
+ documentation for details and revise your code accordingly: this change was
+ unfortunately needed as the old class didn't behave correctly in all cases
+
+- small change to wxStopWatch::Pause() semantics, please see the documentation
+
+- unlikely but possible incompatibility: the definition of TRUE has changed
+ from "1" to "(bool)1" (and the same thing for FALSE), so the code which
+ could be erroneously compiled previously such as doing "return FALSE" from
+ a function returning a pointer would stop compiling now (but this change
+ is not supposed to have any effects on valid code)
