tabbedarea.hpp
namespace gcn
[+] class TabbedArea (1)

	Change	Effect
1	Size of this class has been increased from 228 bytes to 232 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Symbols, High Severity (1)

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN3gcn9ImageFont16getStringIndexAtERKSsi to _ZNK3gcn9ImageFont16getStringIndexAtERKSsi. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Low Severity (2)

	Change	Effect
