wx.Image: Fixed to preserve alpha channel in Rotate90 method.
+wxMSW: Fixed incorrect background colour on wx.CheckListBox.
+
+wxMSW: Fixed drawing of owner drawn buttons with multiline labels
+
+Removed a bunch of unnecessary files, and removed or replaced images
+that we're not sure of their origin or license.
+
+The default DoGetBestSize is updated to not always return the current
+size if the window has no sizer, children, or minsize set. Instead
+the current size is set as the minsize. This solves the occasional
+problem where a sizer may cause a childless panel to grow but never
+shrink.
+
+wxMSW: When converting a wx.Icon to a bitmap check if the icon has an
+alpha channel and set the bitmap to use it.
