This file gives a brief overview of the major changes between each OpenSSL
release. For more details please read the CHANGES file.
Major changes between OpenSSL 0.9.6 and OpenSSL 0.9.7:
o New library section OCSP.
o Complete haul-over of the ASN.1 library section.
Major changes between OpenSSL 0.9.6 and OpenSSL 0.9.6a:
o Security fix: change behavior of OpenSSL to avoid using
environment variables when running as root.
o Security fix: check the result of RSA-CRT to reduce the
possibility of deducing the private key from an incorrectly
calculated signature.
o Security fix: prevent Bleichenbacher's DSA attack.
o Security fix: Zero the premaster secret after deriving the
master secret in DH ciphersuites.
o Bug fixes for Win32, HP/UX and Irix.
o Bug fixes in BIGNUM, SSL, PKCS#7, PKCS#12, X.509, CONF and
memory checking routines.
o Bug fixes for RSA operations in threaded enviroments.
o Bug fixes in misc. openssl applications.
o Remove a few potential memory leaks.
o Add tighter checks of BIGNUM routines.
o Shared library support has been reworked for generality.
o More documentation.
o New function BN_rand_range()
o Add "-rand" option to openssl s_client and s_server.
Major changes between OpenSSL 0.9.5a and OpenSSL 0.9.6:
o Some documentation for BIO and SSL libraries.
o Enhanced chain verification using key identifiers.
o New sign and verify options to 'dgst' application.
o Support for DER and PEM encoded messages in 'smime' application.
o New 'rsautl' application, low level RSA utility.
o MD4 now included.
o Bugfix for SSL rollback padding check.
Major changes between OpenSSL 0.9.5 and OpenSSL 0.9.5a:
o Bug fixes for Win32, SuSE Linux, NeXTSTEP and FreeBSD 2.2.8
o Shared library support for HPUX and Solaris-gcc
o Support of Linux/IA64
o New 'rand' application
o New way to check for existence of algorithms from scripts
o Automation of 'req' application
o Fixes to make s_client, s_server work under Windows
o Support for multiple fieldnames in SPKACs
o New SPKAC command line utilty and associated library functions
o Options to allow passwords to be obtained from various sources
o New public key PEM format and options to handle it
o Many other fixes and enhancements to command line utilities
o Usable certificate chain verification
o Certificate purpose checking
o Certificate trust settings
o Support of authority information access extension
o Extensions in certificate requests
o Simplified X509 name and attribute routines
o Initial (incomplete) support for international character sets
o New DH_METHOD, DSA_METHOD and enhanced RSA_METHOD
o Read only memory BIOs and simplified creation function
o TLS/SSL protocol bugfixes: Accept TLS 'client hello' in SSL 3.0
record; allow fragmentation and interleaving of handshake and other
data
o RSA_NULL option that removes RSA patent code but keeps other
RSA functionality
o Memory leak detection now allows applications to add extra information
via a per-thread stack
o PRNG robustness improved
o Enhanced support for Alpha Linux
o Experimental MacOS support

Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
o Transparent support for PKCS#8 format private keys: these are used
by several software packages and are more secure than the standard
form
o PKCS#5 v2.0 implementation
o Password callbacks have a new void * argument for application data
o Avoid various memory leaks
o New pipe-like BIO that allows using the SSL library when actual I/O
must be handled by the application (BIO pair)

Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
o Lots of enhancements and cleanups to the Configuration mechanism
o RSA OEAP related fixes
o Added `openssl ca -revoke' option for revoking a certificate
o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
o Source tree cleanups: removed lots of obsolete files
o Thawte SXNet, certificate policies and CRL distribution points
o Preliminary (experimental) S/MIME support
o Support for ASN.1 UTF8String and VisibleString
o Full integration of PKCS#12 code
o Sparc assembler bignum implementation, optimized hash functions
o Fixed a security hole related to session resumption
o Fixed RSA encryption routines for the p < q case
o "ALL" in cipher lists now means "everything except NULL ciphers"
