49 o Enhanced support for Alpha Linux
50 o Experimental MacOS support
52 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
54 o Transparent support for PKCS#8 format private keys: these are used
55 by several software packages and are more secure than the standard
57 o PKCS#5 v2.0 implementation
58 o Password callbacks have a new void * argument for application data
59 o Avoid various memory leaks
60 o New pipe-like BIO that allows using the SSL library when actual I/O
61 must be handled by the application (BIO pair)
63 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
64 o Lots of enhancements and cleanups to the Configuration mechanism
65 o RSA OEAP related fixes
66 o Added `openssl ca -revoke' option for revoking a certificate
67 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
68 o Source tree cleanups: removed lots of obsolete files
69 o Thawte SXNet, certificate policies and CRL distribution points
71 o Preliminary (experimental) S/MIME support
72 o Support for ASN.1 UTF8String and VisibleString
73 o Full integration of PKCS#12 code
74 o Sparc assembler bignum implementation, optimized hash functions
75 o Option to disable selected ciphers
77 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
78 o Fixed a security hole related to session resumption
79 o Fixed RSA encryption routines for the p < q case
80 o "ALL" in cipher lists now means "everything except NULL ciphers"
81 o Support for Triple-DES CBCM cipher
82 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
83 o First support for new TLSv1 ciphers
84 o Added a few new BIOs (syslog BIO, reliable BIO)
85 o Extended support for DSA certificate/keys.
86 o Extended support for Certificate Signing Requests (CSR)
87 o Initial support for X.509v3 extensions
88 o Extended support for compression inside the SSL record layer
