647 * Fixed some portability issues on WinCE, MINIX 3, Plan9
648 (thanks to Benjamin Newman), HP-UX, FreeBSD and Solaris
649 * Improved the performance of the EDH key exchange

657 * Various improvement to the modular exponentiation code
658 * Rewrote the headers to generate the API docs with doxygen
659 * Fixed a bug in ssl_encrypt_buf (incorrect padding was
660 generated) and in ssl_parse_client_hello (max. client
661 version was not properly set), thanks to Didier Rebeix
662 * Fixed another bug in ssl_parse_client_hello: clients with
663 cipherlists larger than 96 bytes were incorrectly rejected
664 * Fixed a couple memory leak in x509_read.c
665
666= Version 0.3 released on 2007-01-01
667
668 * Added server-side SSLv3 and TLSv1.0 support
669 * Multiple fixes to enhance the compatibility with g++,
670 thanks to Xosé Antón Otero Ferreira
671 * Fixed a bug in the CBC code, thanks to dowst; also,
672 the bignum code is no longer dependant on long long
673 * Updated rsa_pkcs1_sign to handle arbitrary large inputs
674 * Updated timing.c for improved compatibility with i386
675 and 486 processors, thanks to Arnaud Cornet
676
677= Version 0.2 released on 2006-12-01
678
679 * Updated timing.c to support ARM and MIPS arch
680 * Updated the MPI code to support 8086 on MSVC 1.5

682 * Fixed a bug in sha2_hmac, thanks to newsoft/Wenfang Zhang
683 * Fixed a bug reported by Adrian Rüegsegger in x509_read_key
684 * Fixed a bug reported by Torsten Lauter in ssl_read_record
685 * Fixed a bug in rsa_check_privkey that would wrongly cause
686 valid RSA keys to be dismissed (thanks to oldwolf)
