Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Field pcc 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, Medium Severity (9)

	Change	Effect
1	Type of 1st parameter pnd has been changed from nfc_device_t const* to nfc_device_t* (became non-const).	This function may change parameter pnd, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Size of this type has been changed from 24 bytes to 28 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type of field transceive has been changed from bool()(nfc_device_spec_t,byte_t const,size_t,byte_t,size_t) to bool()(nfc_device_t,byte_t const,size_t,byte_t,size_t*).	Replacement of field base type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field iLastError 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	Size of this type has been changed from 272 bytes to 280 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
