14 o Support for multiple fieldnames in SPKACs
15 o New SPKAC command line utilty and associated library functions

26 o New DH_METHOD, DSA_METHOD and enhanced RSA_METHOD
27 o Read only memory BIOs and simplified creation function
28 o TLS/SSL protocol bugfixes: Accept TLS 'client hello' in SSL 3.0
29 record; allow fragmentation and interleaving of handshake and other
31 o TLS/SSL code now "tolerates" MS SGC
32 o Work around for Netscape client certificate hang bug
33 o RSA_NULL option that removes RSA patent code but keeps other
35 o Memory leak detection now allows applications to add extra information
36 via a per-thread stack
37 o PRNG robustness improved
38 o BIGNUM library bug fixes
39 o faster DSA parameter generation
40 o Enhanced support for Alpha Linux
41 o Experimental MacOS support
43 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
45 o Transparent support for PKCS#8 format private keys: these are used
46 by several software packages and are more secure than the standard
48 o PKCS#5 v2.0 implementation
49 o Password callbacks have a new void * argument for application data
50 o Avoid various memory leaks
51 o New pipe-like BIO that allows using the SSL library when actual I/O
52 must be handled by the application (BIO pair)
54 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
55 o Lots of enhancements and cleanups to the Configuration mechanism
56 o RSA OEAP related fixes
57 o Added `openssl ca -revoke' option for revoking a certificate
58 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
59 o Source tree cleanups: removed lots of obsolete files
60 o Thawte SXNet, certificate policies and CRL distribution points
62 o Preliminary (experimental) S/MIME support
63 o Support for ASN.1 UTF8String and VisibleString
64 o Full integration of PKCS#12 code
65 o Sparc assembler bignum implementation, optimized hash functions
66 o Option to disable selected ciphers
68 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
69 o Fixed a security hole related to session resumption
70 o Fixed RSA encryption routines for the p < q case
71 o "ALL" in cipher lists now means "everything except NULL ciphers"
72 o Support for Triple-DES CBCM cipher
73 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
74 o First support for new TLSv1 ciphers
75 o Added a few new BIOs (syslog BIO, reliable BIO)
76 o Extended support for DSA certificate/keys.
77 o Extended support for Certificate Signing Requests (CSR)
78 o Initial support for X.509v3 extensions
79 o Extended support for compression inside the SSL record layer
80 o Overhauled Win32 builds
81 o Cleanups and fixes to the Big Number (BN) library
82 o Support for ASN.1 GeneralizedTime

84 o ASN1 and PEM support for Netscape Certificate Sequences
85 o Overhauled Perl interface
86 o Lots of source tree cleanups.
87 o Lots of memory leak fixes.
90 Major changes between SSLeay 0.9.0b and OpenSSL 0.9.1c:
91 o Integration of the popular NO_RSA/NO_DSA patches
92 o Initial support for compression inside the SSL record layer
93 o Added BIO proxy and filtering functionality
94 o Extended Big Number (BN) library
