storage.hpp
namespace libtorrent
[+] class default_storage (1)

	Change	Effect
1	Size of this class has been increased from 60 bytes to 68 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.

storage.hpp
namespace libtorrent
[+] class default_storage (1)

	Change	Effect
1	Field m_file_created has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Symbols, Low Severity (3)

	Change	Effect
1	The default argument of 1st parameter user_agent_ has been changed from "libtorrent/0.16.13.0" to "libtorrent/0.16.14.0".	Applications will pass an old default (compile-time) argument that may not be properly handled anymore. This may result in crash or incorrect behavior of applications.
