_______________
Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
to data. This was previously part of the PKCS7 ASN1 code. This
was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
[Steve Henson, reported by Kenneth R. Robinette
<support@securenetterm.com>]
*) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
routines: without these tracing memory leaks is very painful.
Fix leaks in PKCS12 and PKCS7 routines.
[Steve Henson]
*) Fix for Irix with NO_ASM.
