  Changes between 1.0.1 and 1.1.0  [xx XXX xxxx]
 
+  *) Add support for certificate stores in CERT structure. This makes it
+     possible to have different stores per SSL structure or one store in
+     the parent SSL_CTX. Include distint stores for certificate chain
+     verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
+     to build and store a certificate chain in CERT structure: returing
+     an error if the chain cannot be built: this will allow applications
+     to test if a chain is correctly configured.
+
+     Note: if the CERT based stores are not set then the parent SSL_CTX
+     store is used to retain compatibility with existing behaviour.

+
+  *) New function ssl_set_client_disabled to set a ciphersuite disabled
+     mask based on the current session, check mask when sending client
+     hello and checking the requested ciphersuite.
+     [Steve Henson]
+
+  *) New ctrls to retrieve and set certificate types in a certificate
+     request message. Print out received values in s_client. If certificate
+     types is not set with custom values set sensible values based on
+     supported signature algorithms.
+     [Steve Henson]
+
+  *) Support for distinct client and server supported signature algorithms.
+     [Steve Henson]
+
+  *) Add certificate callback. If set this is called whenever a certificate
+     is required by client or server. An application can decide which
+     certificate chain to present based on arbitrary criteria: for example
+     supported signature algorithms. Add very simple example to s_server.
+     This fixes many of the problems and restrictions of the existing client
+     certificate callback: for example you can now clear an existing
+     certificate and specify the whole chain.
+     [Steve Henson]
+
+  *) Add new "valid_flags" field to CERT_PKEY structure which determines what
+     the certificate can be used for (if anything). Set valid_flags field 
+     in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
+     to have similar checks in it.
+
+     Add new "cert_flags" field to CERT structure and include a "strict mode".
+     This enforces some TLS certificate requirements (such as only permitting
+     certificate signature algorithms contained in the supported algorithms
+     extension) which some implementations ignore: this option should be used
+     with caution as it could cause interoperability issues.
+     [Steve Henson]
+
+  *) Update and tidy signature algorithm extension processing. Work out
+     shared signature algorithms based on preferences and peer algorithms
+     and print them out in s_client and s_server. Abort handshake if no
+     shared signature algorithms.
+     [Steve Henson]
+
   *) Add new functions to allow customised supported signature algorithms
      for SSL and SSL_CTX structures. Add options to s_client and s_server
      to support them.
