Version 0.8.6 (25/03/2003)
- Corrected a parsing error in the Certificate request message.
- Corrected behaviour when a certificate request message is received.
  Now a certificate packet is always sent, and in SSL 3.0 cipher suites
  a no_certificate alert is sent instead.

Version 0.8.5 (22/03/2003)
- Allow larger MPI parameters in certificates.
- Implemented the counter measure discussed in the paper "Attacking
  RSA-based Sessions in SSL/TLS", against the attack discribed in the
  same paper.

  distinguished name in a single string.

- If libtasn1 is not present in the system, it is included in 
  the main gnutls library.
- If liblzo is present in the system, then the included minilzo
  will not be used, and libgnutls-extra will depend on liblzo.
- GNUTLS_E_PARSING_ERROR error code was replaced by GNUTLS_E_BASE64_DECODING_ERROR, 
  and GNUTLS_E_SRP_PWD_PARSING_ERROR. GNUTLS_E_ASCII_ARMOR_ERROR was also 
  replaced by GNUTLS_E_BASE64_DECODING_ERROR.

   gnutls_free()
  which should be used by callback functions.
- Changed the semantics of gnutls_pem_base64_encode_alloc()
  and gnutls_pem_base64_decode_alloc(). In the default case
  were the gnutls library is used with malloc/realloc/free,
  these are binary compatible.

  are acceptable.
