     SSL contexts without needing to set all non-connection-specific
	 data and pointers again. Adapted ssl_server to use this functionality.

     encryption and private key for decryption. (Closes ticket #34)

     management (Closes ticket #44)
   * Changed the used random function pointer to more flexible format. Renamed
     havege_rand() to havege_random() to prevent mistakes. Lots of changes as
	 a consequence in library code and programs
   * Moved all examples programs to use the new entropy and CTR_DRBG
   * Added permissive certificate parsing to x509parse_crt() and
     x509parse_crtfile(). With permissive parsing the parsing does not stop on
	 encountering a parse-error. Beware that the meaning of return values has
	 changed!
   * All error codes are now negative. Even on mermory failures and IO errors.

Bugfix
   * Fixed faulty HMAC-MD2 implementation. Found by dibac. (Closes
     ticket #37)
   * Fixed a bug where the CRL parser expected an EXPLICIT ASN.1 tag
     before version numbers

     standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
   * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
     smaller than the hash length. (Closes ticket #41)

     appended with '....' after first 28 octets
   * Improved build support for s390x and sparc64 in bignum.h
   * Fixed MS Visual C++ name clash with int64 in sha4.h
   * Corrected removal of leading "00:" in printing serial numbers in
     certificates and CRLs

     #18)

= Version 0.99-pre5 released on 2011-05-26
Features
   * Added additional Cipher Block Modes to symmetric ciphers
     (AES CTR, Camellia CTR, XTEA CBC) including the option to
	 enable and disable individual modes when needed
   * Functions requiring File System functions can now be disabled
     by undefining POLARSSL_FS_IO
   * A error_strerror function() has been added to translate between
     error codes and their description.
   * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
     functions.
   * Added ssl_mail_client and ssl_fork_server as example programs.

Changes
   * Major argument / variable rewrite. Introduced use of size_t
     instead of int for buffer lengths and loop variables for
	 better unsigned / signed use. Renamed internal bigint types
	 t_int and t_dbl to t_uint and t_udbl in the process
   * mpi_init() and mpi_free() now only accept a single MPI
     argument and do not accept variable argument lists anymore.
   * The error codes have been remapped and combining error codes
     is now done with a PLUS instead of an OR as error codes
	 used are negative.
   * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
     net_recv() now returns 0 on EOF instead of
	 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
	 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
	 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
	 after the handshake.
   * Network functions now return POLARSSL_ERR_NET_WANT_READ or
     POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
	 POLARSSL_ERR_NET_TRY_AGAIN

= Version 0.99-pre4 released on 2011-04-01
Features

     for the RSAES-OAEP and RSASSA-PSS operations.
   * Reading of Public Key files incorporated into default x509
     functionality as well.
   * Added mpi_fill_random() for centralized filling of big numbers
     with random data (Fixed ticket #10)

Changes
   * Debug print of MPI now removes leading zero octets and 
     displays actual bit size of the value.
   * x509parse_key() (and as a consequence x509parse_keyfile()) 
     does not zeroize memory in advance anymore. Use rsa_init()
	 before parsing a key or keyfile!

Bugfix
   * Debug output of MPI's now the same independent of underlying
     platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads
	 Kiilerich and Mihai Militaru)
   * Fixed bug in ssl_write() when flushing old data (Fixed ticket
     #18, found by Nikolay Epifanov)

     length salt lengths

     of ssl_session have been renamed to ciphersuites and

    * Rewrote the headers to generate the API docs with doxygen
    * Fixed a bug in ssl_encrypt_buf (incorrect padding was
      generated) and in ssl_parse_client_hello (max. client
      version was not properly set), thanks to Didier Rebeix
    * Fixed another bug in ssl_parse_client_hello: clients with

    * Fixed a bug reported by Adrian Rüegsegger in x509_read_key
    * Fixed a bug reported by Torsten Lauter in ssl_read_record
    * Fixed a bug in rsa_check_privkey that would wrongly cause
      valid RSA keys to be dismissed (thanks to oldwolf)
    * Fixed a bug in mpi_is_prime that caused some primes to fail
