16
17  Major changes between OpenSSL 0.9.4 and OpenSSL 0.9.5:
18
19      o S/MIME support in new 'smime' command
20      o Documentation for the OpenSSL command line application
21      o Automation of 'req' application
22      o Fixes to make s_client, s_server work under Windows
23      o Support for multiple fieldnames in SPKACs
24      o New SPKAC command line utilty and associated library functions
25      o Options to allow passwords to be obtained from various sources
26      o New public key PEM format and options to handle it
27      o Many other fixes and enhancements to command line utilities
28      o Usable certificate chain verification
29      o Certificate purpose checking
30      o Certificate trust settings
31      o Support of authority information access extension
32      o Extensions in certificate requests
33      o Simplified X509 name and attribute routines
34      o Initial (incomplete) support for international character sets
35      o New DH_METHOD, DSA_METHOD and enhanced RSA_METHOD
36      o Read only memory BIOs and simplified creation function
37      o TLS/SSL protocol bugfixes: Accept TLS 'client hello' in SSL 3.0
38        record; allow fragmentation and interleaving of handshake and other
39        data
40      o TLS/SSL code now "tolerates" MS SGC
41      o Work around for Netscape client certificate hang bug
42      o RSA_NULL option that removes RSA patent code but keeps other
43        RSA functionality
44      o Memory leak detection now allows applications to add extra information
45        via a per-thread stack
46      o PRNG robustness improved
47      o EGD support
48      o BIGNUM library bug fixes
49      o Faster DSA parameter generation
50      o Enhanced support for Alpha Linux
51      o Experimental MacOS support
52
53  Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
54
55      o Transparent support for PKCS#8 format private keys: these are used
56        by several software packages and are more secure than the standard
57        form
58      o PKCS#5 v2.0 implementation
59      o Password callbacks have a new void * argument for application data
60      o Avoid various memory leaks
61      o New pipe-like BIO that allows using the SSL library when actual I/O
62        must be handled by the application (BIO pair)
63
64  Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
65      o Lots of enhancements and cleanups to the Configuration mechanism
66      o RSA OEAP related fixes
67      o Added `openssl ca -revoke' option for revoking a certificate
68      o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
69      o Source tree cleanups: removed lots of obsolete files
70      o Thawte SXNet, certificate policies and CRL distribution points
71        extension support
72      o Preliminary (experimental) S/MIME support
73      o Support for ASN.1 UTF8String and VisibleString
74      o Full integration of PKCS#12 code
75      o Sparc assembler bignum implementation, optimized hash functions
76      o Option to disable selected ciphers
77
78  Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
79      o Fixed a security hole related to session resumption
80      o Fixed RSA encryption routines for the p < q case
81      o "ALL" in cipher lists now means "everything except NULL ciphers"

83      o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
84      o First support for new TLSv1 ciphers

86      o Extended support for DSA certificate/keys.
87      o Extended support for Certificate Signing Requests (CSR)
