  33
  34   * Fixed invalid handling of X509_verify_cert() internal errors in libssl
  35     ([CVE-2021-4044])
  36   * Allow fetching an operation from the provider that owns an unexportable key
  37     as a fallback if that is still allowed by the property query.
  38
  39 ### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0.0
  40
  41   * Enhanced 'openssl list' with many new options.
  42   * Added migration guide to man7.
  43   * Implemented support for fully "pluggable" TLSv1.3 groups.
  44   * Added suport for Kernel TLS (KTLS).
  45   * Changed the license to the Apache License v2.0.
  46   * Moved all variations of the EVP ciphers CAST5, BF, IDEA, SEED, RC2,
  47     RC4, RC5, and DES to the legacy provider.
  48   * Moved the EVP digests MD2, MD4, MDC2, WHIRLPOOL and RIPEMD-160 to the legacy
  49     provider.
  50   * Added convenience functions for generating asymmetric key pairs.
  51   * Deprecated the `OCSP_REQ_CTX` type and functions.
  52   * Deprecated the `EC_KEY` and `EC_KEY_METHOD` types and functions.
  53   * Deprecated the `RSA` and `RSA_METHOD` types and functions.
  54   * Deprecated the `DSA` and `DSA_METHOD` types and functions.
  55   * Deprecated the `DH` and `DH_METHOD` types and functions.
  56   * Deprecated the `ERR_load_` functions.
  57   * Remove the `RAND_DRBG` API.
  58   * Deprecated the `ENGINE` API.
  59   * Added `OSSL_LIB_CTX`, a libcrypto library context.

  64     included in the FIPS provider.
  65   * X509 certificates signed using SHA1 are no longer allowed at security
  66     level 1 or higher. The default security level for TLS is 1, so
  67     certificates signed using SHA1 are by default no longer trusted to
  68     authenticate servers or clients.
  69   * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
  70     disabled; the project uses address sanitize/leak-detect instead.

  76     arbitrary request and response content types, TLS, persistent connections,
  77     connections via HTTP(s) proxies, connections and exchange via user-defined
  78     BIOs (allowing implicit connections), and timeout checks.

  85     ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and
  86     ERR_func_error_string().
  87   * Added OSSL_PROVIDER_available(), to check provider availibility.
  88   * Added 'openssl mac' that uses the EVP_MAC API.
  89   * Added 'openssl kdf' that uses the EVP_KDF API.

 100     EVP_KDF bridge.  Supported KDFs are: HKDF, KBKDF, KRB5 KDF, PBKDF2,
 101     PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
 102   * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
 103     SHA256, SHA384, SHA512 and Whirlpool digest functions have been
 104     deprecated.
 105   * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
 106     RC4, RC5 and SEED cipher functions have been deprecated.
 107   * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
 108     have been deprecated.
 109   * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
