Version 0.5.12
- Added "gnutls/compat4.h" header. This is included in gnutls.h
  to emulate the old 0.4.x API.
- Example programs are now stored in doc/examples/
- Added the certificate authenticated SRP cipher suites.
- gnutls_x509_extract_certificate_dn_string() was updated to return
  an RFC2253 conforming string.
- Added the SRP related functions:
   gnutls_srp_verifier()
   gnutls_srp_base64_encode()
   gnutls_srp_base64_decode()
- Added the function gnutls_srp_set_server_credentials_function()
  to allow retrieving SRP parameters from an external backend - other
  than password files.
- Added the function gnutls_openpgp_set_recv_key_function()
  which can be used to set a callback, to get OpenPGP keys.
- Exported the functions:
   gnutls_malloc()
   gnutls_free()
  which should be used in callbacks.
- 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.

Version 0.5.11 (5/11/2002)
- Some fixes in 'gnutls-cli' client program to prevent some segmentation 
  faults at exit.
- Example programs found in the documentation can now be generated by
  running "make examples" in doc/tex directory.

  case where the memory buffer provided is not long enough.

  checkings.

- Corrected some code which worked fine in gcc 3.2, but not with any
  other compiler.
- Updated 'gnutls-cli' with the '--starttls' option, to allow testing
  starttls implementations.
- Added gnutls_x509_extract_key_pk_algorithm() function which extracts
  the private key type, of a DER encoded key.

  certificate's distinguished name in a single string.

  functions, to avoid calling all the *_priority() functions if the defaults
  are acceptable.

  the given hostname matches the owner of the given X.509 certificate.

Version 0.5.8 (25/09/2002)

  crypt implementation was removed, since the new draft does not allow
  other hash algorithms except for the srpsha. 
- Renamed all the constructed types in order to have more consistent
  names.

  the certificate and the private key from the same file.

  code from the unstable branch.

Version 0.5.2 (22/08/2002)

  to export only servers. This must be enabled using the

  while sending data.

  size is now immediately enforced at the output buffers.

  be used in these programs, to assist in debuging.
- Fixes in zlib compression code.

Version 0.5.0 (6/07/2002)
