Problems with Data Types, Low Severity (3)

	Change	Effect
1	Base type of field f_rng has been changed from *int()(void)* to int()(void,unsigned char*,size_t).	Replacement of field base type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Base type has been changed from struct _x509_buf to struct _asn1_buf.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _x509_sequence to struct _asn1_sequence.	Possible incorrect initialization of parameters by applications.

Problems with Constants (2)

	Change	Effect
1	The value of constant POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL has been changed from -0x0010 to -0x002A.	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 POLARSSL_ERR_BASE64_INVALID_CHARACTER has been changed from -0x0012 to -0x002C.	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.
