50 o Enhanced support for Alpha Linux
51 o Experimental MacOS support
53 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
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
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)
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

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
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
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"
82 o Support for Triple-DES CBCM cipher
83 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
84 o First support for new TLSv1 ciphers
85 o Added a few new BIOs (syslog BIO, reliable BIO)
86 o Extended support for DSA certificate/keys.
