5 This file gives a brief overview of the major changes between each OpenSSL
6 release. For more details please read the CHANGES file.
8 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
10 o Transparent support for PKCS#8 format private keys: these are used
11 by several software packages and are more secure than the standard
13 o PKCS#5 v2.0 implementation
14 o Password callbacks have a new void * argument for application data
15 o Avoid various memory leaks
16 o New pipe-like BIO that allows using the SSL library when actual I/O
17 must be handled by the application (BIO pair)
19 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
20 o Lots of enhancements and cleanups to the Configuration mechanism
21 o RSA OEAP related fixes
22 o Added `openssl ca -revoke' option for revoking a certificate
23 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
24 o Source tree cleanups: removed lots of obsolete files
25 o Thawte SXNet, certificate policies and CRL distribution points
27 o Preliminary (experimental) S/MIME support
28 o Support for ASN.1 UTF8String and VisibleString
29 o Full integration of PKCS#12 code
30 o Sparc assembler bignum implementation, optimized hash functions
31 o Option to disable selected ciphers
33 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
34 o Fixed a security hole related to session resumption
35 o Fixed RSA encryption routines for the p < q case
36 o "ALL" in cipher lists now means "everything except NULL ciphers"
37 o Support for Triple-DES CBCM cipher
38 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
39 o First support for new TLSv1 ciphers
