22### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0 [under development] ###
23
24 * The algorithm specific public key command line applications have
25 been deprecated. These include dhparam, gendsa and others. The pkey
26 alternatives should be used intead: pkey, pkeyparam and genpkey.
27 * X509 certificates signed using SHA1 are no longer allowed at security
28 level 1 or higher. The default security level for TLS is 1, so
29 certificates signed using SHA1 are by default no longer trusted to
30 authenticate servers or clients.
5f8e6c50
DMSP
31 * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
32 disabled; the project uses address sanitize/leak-detect instead.
33 * Added OSSL_SERIALIZER, a generic serializer API.
be19d3ca 34 * Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.
5f8e6c50
DMSP
35 * Added error raising macros, ERR_raise() and ERR_raise_data().

37 * Added OSSL_PROVIDER_available(), to check provider availibility.
38 * Added 'openssl mac' that uses the EVP_MAC API.
39 * Added 'openssl kdf' that uses the EVP_KDF API.
40 * Add OPENSSL_info() and 'openssl info' to get built-in data.
41 * Add support for enabling instrumentation through trace and debug
42 output.
43 * Changed our version number scheme and set the next major release to
44 3.0.0
45 * Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC
46 bridge.
