6 release. For more details please read the CHANGES file.
8 Major changes between OpenSSL 0.9.4 and OpenSSL 0.9.5:
11 o Documentation for the OpenSSL command line application
14 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
16 o Transparent support for PKCS#8 format private keys: these are used
17 by several software packages and are more secure than the standard
19 o PKCS#5 v2.0 implementation
20 o Password callbacks have a new void * argument for application data
21 o Avoid various memory leaks
22 o New pipe-like BIO that allows using the SSL library when actual I/O
23 must be handled by the application (BIO pair)
25 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
26 o Lots of enhancements and cleanups to the Configuration mechanism
27 o RSA OEAP related fixes
28 o Added `openssl ca -revoke' option for revoking a certificate
29 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
30 o Source tree cleanups: removed lots of obsolete files
31 o Thawte SXNet, certificate policies and CRL distribution points
33 o Preliminary (experimental) S/MIME support
34 o Support for ASN.1 UTF8String and VisibleString
35 o Full integration of PKCS#12 code
36 o Sparc assembler bignum implementation, optimized hash functions
37 o Option to disable selected ciphers
39 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
40 o Fixed a security hole related to session resumption
41 o Fixed RSA encryption routines for the p < q case
