o Change default private key format to PKCS#8.
o CMS support: able to process all examples in RFC4134
o Streaming ASN1 encode support for PKCS#7 and CMS.
o Multiple signer and signer add support for PKCS#7 and CMS.
o ASN1 printing support.
o Whirlpool hash algorithm added.
o RFC3161 time stamp support.
o New generalised public key API supporting ENGINE based algorithms.
o New generalised public key API utilities.
o New ENGINE supporting GOST algorithms.
o SSL/TLS GOST ciphersuite support.
o PKCS#7 and CMS GOST support.
o RFC4279 PSK ciphersuite support.
o Supported points format extension for ECC ciphersuites.
o ecdsa-with-SHA224/256/384/512 signature types.
o dsa-with-SHA224 and dsa-with-SHA256 signature types.
o Opaque PRF Input TLS extension support.
o Updated time routines to avoid OS limitations.
