 Changes between 1.1.0 and 1.1.1 [xx XXX xxxx]

  *)

 Changes between 1.0.2h and 1.1.0  [25 Aug 2016]
  *) Windows command-line tool supports UTF-8 opt-in option for arguments
     and console input. Setting OPENSSL_WIN32_UTF8 environment variable
     (to any value) allows Windows user to access PKCS#12 file generated
     with Windows CryptoAPI and protected with non-ASCII password, as well
     as files generated under UTF-8 locale on Linux also protected with
     non-ASCII password.
     [Andy Polyakov]

  *) To mitigate the SWEET32 attack (CVE-2016-2183), 3DES cipher suites
     have been disabled by default and removed from DEFAULT, just like RC4.
     See the RC4 item below to re-enable both.
  *) The method for finding the storage location for the Windows RAND seed file
     has changed. First we check %RANDFILE%. If that is not set then we check
     the directories %HOME%, %USERPROFILE% and %SYSTEMROOT% in that order. If
     all else fails we fall back to C:\.
  *) The EVP_EncryptUpdate() function has had its return type changed from void
     to int. A return of 0 indicates and error while a return of 1 indicates
     success.
     [Matt Caswell]

  *) The flags RSA_FLAG_NO_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME and
     DH_FLAG_NO_EXP_CONSTTIME which previously provided the ability to switch
     off the constant time implementation for RSA, DSA and DH have been made
     no-ops and deprecated.

  *) Windows RAND implementation was simplified to only get entropy by
     calling CryptGenRandom(). Various other RAND-related tickets
     were also closed.
     [Joseph Wylie Yandle, Rich Salz]

  *) The stack and lhash API's were renamed to start with OPENSSL_SK_
     and OPENSSL_LH_, respectively.  The old names are available
     with API compatibility.  They new names are now completely documented.
     [Rich Salz]

  *) Unify TYPE_up_ref(obj) methods signature.
     SSL_CTX_up_ref(), SSL_up_ref(), X509_up_ref(), EVP_PKEY_up_ref(),
     X509_CRL_up_ref(), X509_OBJECT_up_ref_count() methods are now returning an
     int (instead of void) like all others TYPE_up_ref() methods.
     So now these methods also check the return value of CRYPTO_atomic_add(),
     and the validity of object reference counter.

  *) With Windows Visual Studio builds, the .pdb files are installed
     alongside the installed libraries and executables.  For a static
     library installation, ossl_static.pdb is the associate compiler
     generated .pdb file to be used when linking programs.

  *) Remove openssl.spec.  Packaging files belong with the packagers.
     [Richard Levitte]

  *) Automatic Darwin/OSX configuration has had a refresh, it will now
     recognise x86_64 architectures automatically.  You can still decide
     to build for a different bitness with the environment variable
     KERNEL_BITS (can be 32 or 64), for example:

         KERNEL_BITS=32 ./config

     [Richard Levitte]

  *) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0,
     256 bit AES and HMAC with SHA256.

  *) Remove support for MIPS o32 ABI on IRIX (and IRIX only).

  *) To enable users to have their own config files and build file templates,
     Configure looks in the directory indicated by the environment variable
     OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/
     directory.  On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical
     name and is used as is.
     [Richard Levitte]

  *) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX,
     X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD.  The unused type
     X509_CERT_FILE_CTX was removed.
     [Rich Salz]

  *) "shared" builds are now the default. To create only static libraries use
     the "no-shared" Configure option.
     [Matt Caswell]

  *) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
     All of these option have not worked for some while and are fundamental
     algorithms.
     [Matt Caswell]

  *) Make various cleanup routines no-ops and mark them as deprecated. Most
     global cleanup functions are no longer required because they are handled
     via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
     Explicitly de-initing can cause problems (e.g. where a library that uses
     OpenSSL de-inits, but an application is still using it). The affected
     functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),
     EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),
     RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and
     COMP_zlib_cleanup().
     [Matt Caswell]
  *) --strict-warnings no longer enables runtime debugging options
     such as REF_DEBUG. Instead, debug options are automatically
     enabled with '--debug' builds.
     [Andy Polyakov, Emilia Käsper]

  *) Made DH and DH_METHOD opaque. The structures for managing DH objects
     have been moved out of the public header files. New functions for managing
     these have been added.
     [Matt Caswell]

  *) Made RSA and RSA_METHOD opaque. The structures for managing RSA
     objects have been moved out of the public header files. New
     functions for managing these have been added.
     [Richard Levitte]

  *) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects
     have been moved out of the public header files. New functions for managing
     these have been added.
     [Matt Caswell]

  *) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been
     moved out of the public header files. New functions for managing these
     have been added.
     [Matt Caswell]

  *) Removed no-rijndael as a config option. Rijndael is an old name for AES.
     [Matt Caswell]
  *) Removed the mk1mf build scripts.
     [Richard Levitte]

  *) Headers are now wrapped, if necessary, with OPENSSL_NO_xxx, so
     it is always safe to #include a header now.
     [Rich Salz]

  *) Removed the aged BC-32 config and all its supporting scripts
     [Richard Levitte]

  *) Added support for "pipelining". Ciphers that have the
     EVP_CIPH_FLAG_PIPELINE flag set have a capability to process multiple
     encryptions/decryptions simultaneously. There are currently no built-in
     ciphers with this property but the expectation is that engines will be able
     to offer it to significantly improve throughput. Support has been extended
     into libssl so that multiple records for a single connection can be
     processed in one go (for >=TLS 1.1).
     [Matt Caswell]

  *) Added the AFALG engine. This is an async capable engine which is able to
     offload work to the Linux kernel. In this initial version it only supports
     AES128-CBC. The kernel must be version 4.1.0 or greater.
     [Catriona Lucey]

  *) OpenSSL now uses a new threading API. It is no longer necessary to
     set locking callbacks to use OpenSSL in a multi-threaded environment. There
     are two supported threading models: pthreads and windows threads. It is
     also possible to configure OpenSSL at compile time for "no-threads". The
     old threading API should no longer be used. The functions have been
     replaced with "no-op" compatibility macros.

  *) Modify behavior of ALPN to invoke callback after SNI/servername
     callback, such that updates to the SSL_CTX affect ALPN.

  *) Add SSL_CIPHER queries for authentication and key-exchange.
     [Todd Short]

  *) Changes to the DEFAULT cipherlist:
       - Prefer (EC)DHE handshakes over plain RSA.
       - Prefer AEAD ciphers over legacy ciphers.
       - Prefer ECDSA over RSA when both certificates are available.
       - Prefer TLSv1.2 ciphers/PRF.
       - Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the
Loading full blame...
