Problems with Constants (3)

	Change	Effect
1	The value of constant CERT_FIRST_RESERVED_PROP_ID has been changed from 72 to 85.	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 CERT_QUERY_CONTENT_FLAG_ALL has been changed from CERT_QUERY_CONTENT_FLAG_CERT \| CERT_QUERY_CONTENT_FLAG_CTL \| CERT_QUERY_CONTENT_FLAG_CRL \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_STORE \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CERT \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CTL \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CRL \| CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED \| CERT_QUERY_CONTENT_FLAG_PKCS7_UNSIGNED \| CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED_EMBED \| CERT_QUERY_CONTENT_FLAG_PKCS10 \| CERT_QUERY_CONTENT_FLAG_PFX \| CERT_QUERY_CONTENT_FLAG_CERT_PAIR to ( CERT_QUERY_CONTENT_FLAG_CERT \| CERT_QUERY_CONTENT_FLAG_CTL \| CERT_QUERY_CONTENT_FLAG_CRL \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_STORE \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CERT \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CTL \| CERT_QUERY_CONTENT_FLAG_SERIALIZED_CRL \| CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED \| CERT_QUERY_CONTENT_FLAG_PKCS7_UNSIGNED \| CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED_EMBED \| CERT_QUERY_CONTENT_FLAG_PKCS10 \| CERT_QUERY_CONTENT_FLAG_PFX \| CERT_QUERY_CONTENT_FLAG_CERT_PAIR ).
