632 thanks to Peking University and the OSU Open Source Lab

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

648 size of 16384 bytes to be rejected
649
650= Version 0.4 released on 2007-02-01
651
652 * Added support for Ephemeral Diffie-Hellman key exchange

654 * Various improvement to the modular exponentiation code
655 * Rewrote the headers to generate the API docs with doxygen
656 * Fixed a bug in ssl_encrypt_buf (incorrect padding was
657 generated) and in ssl_parse_client_hello (max. client
658 version was not properly set), thanks to Didier Rebeix
659 * Fixed another bug in ssl_parse_client_hello: clients with
660 cipherlists larger than 96 bytes were incorrectly rejected
661 * Fixed a couple memory leak in x509_read.c
662
663= Version 0.3 released on 2007-01-01
664

666 * Multiple fixes to enhance the compatibility with g++,
667 thanks to Xosé Antón Otero Ferreira
668 * Fixed a bug in the CBC code, thanks to dowst; also,
669 the bignum code is no longer dependant on long long
670 * Updated rsa_pkcs1_sign to handle arbitrary large inputs
671 * Updated timing.c for improved compatibility with i386
672 and 486 processors, thanks to Arnaud Cornet
673

675
676 * Updated timing.c to support ARM and MIPS arch
677 * Updated the MPI code to support 8086 on MSVC 1.5
678 * Added the copyright notice at the top of havege.h
679 * Fixed a bug in sha2_hmac, thanks to newsoft/Wenfang Zhang
680 * Fixed a bug reported by Adrian Rüegsegger in x509_read_key
681 * Fixed a bug reported by Torsten Lauter in ssl_read_record
682 * Fixed a bug in rsa_check_privkey that would wrongly cause
683 valid RSA keys to be dismissed (thanks to oldwolf)
