Paul Bakker23986e52011-04-24 08:57:21 +0000728Changes
729 * Major argument / variable rewrite. Introduced use of size_t
730 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100731 better unsigned / signed use. Renamed internal bigint types
732 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000733 * mpi_init() and mpi_free() now only accept a single MPI
734 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000735 * The error codes have been remapped and combining error codes
736 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100737 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000738 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
739 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100740 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
741 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
742 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
743 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000744 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
745 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +0100746 POLARSSL_ERR_NET_TRY_AGAIN
