- Assert messages now show the function in which assert failed
- wxApp::OnAssertFailure() should now be used instead the old wxApp::OnAssert()
- Fixed several bugs in wxDateTime::ParseDate()
- The WXK*PRIOR and WXK*NEXT constants are now aliases for WXK*PAGEUP
- The WXK*PRIOR and WXK*NEXT constants are now aliases for WXK*PAGEUP

constants from a set then you need to remove the PRIOR/NEXT
constants from a set then you need to remove the PRIOR/NEXT

- Fixed bug where wxDateTime::Now() would sometimes return an incorrect value
