 When adding a spacer to a sizer you now need to use a wx.Size or a
 2-integer sequence instead of separate width and height parameters.
+This allows for more consistency in how you add the various types of
+items to a sizer.  The first parameter defines the item (instead of

+**[Changed in 2.5.1.6]** wx.ADJUST_MINSIZE is now the default
+behaviour for window items in sizers.  This means that the item's
+GetAdjustedBestSize will be called when calculating layout and the
+return value from that will be used for the minimum size.  Added
+wx.FIXED_MINSIZE flag for when you would like the old behavior but you

+isn't already a minimal size.
