Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN2v89ExtensionC1EPKcS2_iPS2_i to _ZN2v89ExtensionC1EPKcS2_iPS2_. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Low Severity (3)

	Change	Effect
1	Size of this type has been changed from 36 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Type of field source_ has been changed from ExternalAsciiStringResourceImpl (12 bytes) to char const* (4 bytes).	Size of the inclusive type has changed.
3	Field source_length_ has been removed from this type.	Size of the inclusive type has been changed.

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Type of return value has been changed from String::ExternalAsciiStringResource const* to String::ExternalAsciiStringResource*.	Replacement of return type may indicate a change in its semantic meaning.
