Paul Bakker828acb22011-05-27 09:25:42 +0000729= Version 0.99-pre5 released on 2011-05-26
Paul Bakkerb6ecaf52011-04-19 14:29:23 +0000730Features
731 * Added additional Cipher Block Modes to symmetric ciphers
732 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100733 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000734 * Functions requiring File System functions can now be disabled
735 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +0000736 * A error_strerror function() has been added to translate between
737 error codes and their description.
Paul Bakker2f5947e2011-05-18 15:47:11 +0000738 * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
739 functions.

Paul Bakker23986e52011-04-24 08:57:21 +0000742Changes
743 * Major argument / variable rewrite. Introduced use of size_t
744 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100745 better unsigned / signed use. Renamed internal bigint types
746 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000747 * mpi_init() and mpi_free() now only accept a single MPI
748 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000749 * The error codes have been remapped and combining error codes
750 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100751 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000752 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
753 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100754 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
755 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
756 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
757 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000758 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
759 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +0100760 POLARSSL_ERR_NET_TRY_AGAIN

773 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +0000774 * x509parse_key() (and as a consequence x509parse_keyfile())
775 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100776 before parsing a key or keyfile!

1119 generated) and in ssl_parse_client_hello (max. client
1120 version was not properly set), thanks to Didier Rebeix
1121 * Fixed another bug in ssl_parse_client_hello: clients with
1122 cipherlists larger than 96 bytes were incorrectly rejected
1123 * Fixed a couple memory leak in x509_read.c
1124
