Changes between 1.0.1 and 1.0.2 [xx XXX xxxx]
+ *) Fixes and wildcard matching support to hostname and email checking
+ functions. Add manual page.
+ [Florian Weimer (Red Hat Product Security Team)]
+
+ *) New functions to check a hostname email or IP address against a
+ certificate. Add options x509 utility to print results of checks against
+ a certificate.
+ [Steve Henson]
+
+ *) Fix OCSP checking.
+ [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie]
+
+ *) Backport support for partial chain verification: if an intermediate
+ certificate is explicitly trusted (using -addtrust option to x509
+ utility for example) the verification is sucessful even if the chain
+ is not complete.
+ The OCSP checking fix depends on this backport.
+ [Steve Henson and Rob Stradling <rob.stradling@comodo.com>]
+
+ *) Add -trusted_first option which attempts to find certificates in the
+ trusted store even if an untrusted chain is also supplied.
+ [Steve Henson]
+
+ *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE,
+ platform support for Linux and Android.
+ [Andy Polyakov]
+
+ *) Call OCSP Stapling callback after ciphersuite has been chosen, so
+ the right response is stapled. Also change current certificate to
+ the certificate actually sent.
+ See http://rt.openssl.org/Ticket/Display.html?id=2836.
+ [Rob Stradling <rob.stradling@comodo.com>]
+
+ *) Support for linux-x32, ILP32 environment in x86_64 framework.
+ [Andy Polyakov]
+
+ *) RFC 5878 support.
+ [Emilia Kasper, Adam Langley, Ben Laurie (Google)]
+
+ *) Experimental multi-implementation support for FIPS capable OpenSSL.
+ When in FIPS mode the approved implementations are used as normal,
+ when not in FIPS mode the internal unapproved versions are used instead.
+ This means that the FIPS capable OpenSSL isn't forced to use the
+ (often lower perfomance) FIPS implementations outside FIPS mode.
+ [Steve Henson]
+
+ *) Transparently support X9.42 DH parameters when calling
+ PEM_read_bio_DHparameters. This means existing applications can handle
+ the new parameter format automatically.
+ [Steve Henson]
+
+ *) Initial experimental support for X9.42 DH parameter format: mainly
+ to support use of 'q' parameter for RFC5114 parameters.
+ [Steve Henson]
+
+ *) Add DH parameters from RFC5114 including test data to dhtest.
+ [Steve Henson]
+
+ *) Support for automatic EC temporary key parameter selection. If enabled
+ the most preferred EC parameters are automatically used instead of
+ hardcoded fixed parameters. Now a server just has to call:
+ SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+ support ECDH and use the most appropriate parameters.
+ [Steve Henson]
+
+ *) Enhance and tidy EC curve and point format TLS extension code. Use
+ static structures instead of allocation if default values are used.
+ New ctrls to set curves we wish to support and to retrieve shared curves.
+ Print out shared curves in s_server. New options to s_server and s_client
+ to set list of supported curves.
+ [Steve Henson]
+
*) New ctrls to retrieve supported signature algorithms and
supported curve values as an array of NIDs. Extend openssl utility
to print out received values.
certificates.

- Changes between 1.0.1 and 1.0.1a [xx XXX xxxx]
+ Changes between 1.0.1c and 1.0.1d [xx XXX xxxx]
+
+ *) Make openssl verify return errors.
+ [Chris Palmer <palmer@google.com> and Ben Laurie]
+
+ *) Fix possible deadlock when decoding public keys.
+ [Steve Henson]
+
+ *) Don't use TLS 1.0 record version number in initial client hello
+ if renegotiating.
+ [Steve Henson]
+
+ Changes between 1.0.1b and 1.0.1c [10 May 2012]
+
+ *) Sanity check record length before skipping explicit IV in TLS
+ 1.2, 1.1 and DTLS to avoid DoS attack.
+
+ Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic
+ fuzzing as a service testing platform.
+ (CVE-2012-2333)
+ [Steve Henson]
+
+ *) Initialise tkeylen properly when encrypting CMS messages.
+ Thanks to Solar Designer of Openwall for reporting this issue.
+ [Steve Henson]
+
+ *) In FIPS mode don't try to use composite ciphers as they are not
+ approved.
+ [Steve Henson]
+
+ Changes between 1.0.1a and 1.0.1b [26 Apr 2012]
+
+ *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
+ 1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+ mean any application compiled against OpenSSL 1.0.0 headers setting
+ SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng
+ TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
+ 0x10000000L Any application which was previously compiled against
+ OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
+ will need to be recompiled as a result. Letting be results in
+ inability to disable specifically TLS 1.1 and in client context,
+ in unlike event, limit maximum offered version to TLS 1.0 [see below].
+ [Steve Henson]
+
+ *) In order to ensure interoperabilty SSL_OP_NO_protocolX does not
+ disable just protocol X, but all protocols above X *if* there are
+ protocols *below* X still enabled. In more practical terms it means
+ that if application wants to disable TLS1.0 in favor of TLS1.1 and
+ above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass
+ SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to
+ client side.
+ [Andy Polyakov]
+
+ Changes between 1.0.1 and 1.0.1a [19 Apr 2012]
+
+ *) Check for potentially exploitable overflows in asn1_d2i_read_bio
+ BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
+ in CRYPTO_realloc_clean.
+
+ Thanks to Tavis Ormandy, Google Security Team, for discovering this
+ issue and to Adam Langley <agl@chromium.org> for fixing it.
+ (CVE-2012-2110)
+ [Adam Langley (Google), Tavis Ormandy, Google Security Team]
+
+ *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+ [Adam Langley]
+
+ *) Workarounds for some broken servers that "hang" if a client hello
+ record length exceeds 255 bytes:
+
+ 1. Do not use record version number > TLS 1.0 in initial client
+ hello: some (but not all) hanging servers will now work.
+ 2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
+ the number of ciphers sent in the client hello. This should be
+ set to an even number, such as 50, for example by passing:
+ -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
+ Most broken servers should now work.
+ 3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
+ TLS 1.2 client support entirely.
+ [Steve Henson]
*) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
