Problems with Data Types, High Severity (4)

	Change	Effect
1	Size of this class has been increased from 60 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 neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been increased from 4896 bytes to 4916 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.

	Change	Effect
1	Size of this class has been increased from 760 bytes to 764 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.

	Change	Effect
1	Size of this class has been changed from 80 bytes to 100 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Size of field m_ses has been changed from 4896 bytes to 4916 bytes.	Previous accesses of applications and library functions to this field may be broken.

	Change	Effect
1	Size of field m_utp_socket_manager has been changed from 80 bytes to 100 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity (7)

	Change	Effect
1	Field m_locked_peer has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of field m_policy has been changed from 60 bytes to 64 bytes.	Size of the inclusive type has been changed.
2	Size of field m_ses has been changed from 4896 bytes to 4916 bytes.	Size of the inclusive type has been changed.

	Change	Effect
1	Field m_interfaces has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field m_last_if_update has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field m_last_route_update became mutable.	The value of this field can begin to change in ways outside the control of old client applications.
4	Field m_routes became mutable.	The value of this field can begin to change in ways outside the control of old client applications.

Problems with Symbols, Low Severity (2)

	Change	Effect
1	The default argument of 1st parameter user_agent_ has been changed from "libtorrent/0.16.5.0" to "libtorrent/0.16.6.0".	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.

	Change	Effect
1	The default argument of 1st parameter user_agent_ has been changed from "libtorrent/0.16.5.0" to "libtorrent/0.16.6.0".	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.

Problems with Constants (2)

	Change	Effect
1	The value of constant TORRENT_USE_WSTRING has been changed from 0 to 1.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant LIBTORRENT_REVISION has been changed from "$Rev: 7607 $" to "$Rev: 7769 $".	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
