	Change	Effect
1	Base class libebml::EbmlUInteger has been added.	1) Size of the class has been changed from 52 bytes to 64 bytes. 2) The memory layout in this class has been shifted by 12 bytes.
2	Base class libebml::EbmlBinary has been removed.	1) Size of the class has been changed from 52 bytes to 64 bytes. 2) The memory layout in this class has been shifted by 12 bytes.
3	Size of this class has been increased from 52 bytes to 64 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 neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.
