Paul Bakkera35aa542013-03-06 17:06:21 +0100521 encountering a parse-error. Beware that the meaning of return values has
522 changed!

Paul Bakker1fe7d9b2011-11-15 15:26:03 +0000532 * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length

556 * Added additional Cipher Block Modes to symmetric ciphers
557 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100558 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000559 * Functions requiring File System functions can now be disabled

568 * Major argument / variable rewrite. Introduced use of size_t
569 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100570 better unsigned / signed use. Renamed internal bigint types
571 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000572 * mpi_init() and mpi_free() now only accept a single MPI
573 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000574 * The error codes have been remapped and combining error codes
575 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100576 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000577 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
578 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100579 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
580 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
581 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
582 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000583 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
