Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been changed from 152 bytes to 160 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 (1)

	Change	Effect
1	Size of field my_embedded_segment has been changed from 16 bytes to 24 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field may be broken.

Problems with Data Types, Low Severity (8)

	Change	Effect
1	Base class internal::mutex_copy_deprecated_and_disabled has been added.	Possible incorrect access of applications to the memory occupied by the base classes.

	Change	Effect
1	Size of this type has been changed from 8 bytes to 12 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

1	Base class internal::mutex_copy_deprecated_and_disabled has been added.	Possible incorrect access of applications to the memory occupied by the base classes.

Problems with Constants, Low Severity (2)

	Change	Effect
1	The constant __TBB_CPP11_STD_FORWARD_BROKEN with value 0 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The value of constant __TBB_TSX_INTRINSICS_PRESENT has been changed from ( (__TBB_GCC_VERSION>=40800) \|\| (_MSC_VER>=1700) \|\| (__INTEL_COMPILER>=1300) ) && !__TBB_DEFINE_MIC && !__ANDROID__ to ((__RTM__ \|\| _MSC_VER>=1700 \|\| __INTEL_COMPILER>=1300) && !__TBB_DEFINE_MIC && !__ANDROID__).	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.
