+ style to avoid it
+
+- all overloads of wxDC::SetClippingRegion() combine the given region with the
+ previously selected one instead of replacing it
+
+- wxGetHomeDir() uses HOME environment variable and if it is set will not
+ return the programs directory any longer but its value (this function has
+ never been meant to return the programs directory anyhow)
+
+- wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
+ anymore. The file was removed from wxMSW
+
+
+Unix ports:
+
+! You should use `wx-config --cxxflags` in your makefiles instead of
+ `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
+ and the compiler flags for C++ files only, CFLAGS should still be used
+ to compile pure C files.
+
+
+wxThread and related classes:
+
+- The thread-related classes have been heavily changed since 2.2.x versions
+ as the old code had many serious problems. This could have resulted in
+ semantical changes other than those mentioned here, please review use of
+ wxThread, wxMutex and wxCondition classes in your code.
+
+! 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 it was impossible to ensure the correct behaviour
+ (i.e. absense of race conditions) using the old API.
+
+- wxMutex is not recursive any more in POSIX implementation (it hasn't been
+ recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
+ documentation for the discussion of the recursive mutexes.
+
+- wxMutex::IsLocked() doesn't exist any more and should have never existed:
+ this is was unique example of a thread-unsafe-by-design method.
+
