  31 ### Major changes between OpenSSL 3.1 and OpenSSL 3.2 [under development]
  32
  33   * Added client side support for QUIC.
  34   * Added multiple tutorials on the OpenSSL library and in particular
  35     on writing various clients (using TLS and QUIC protocols) with libssl.
  36   * Added support for Brainpool curves in TLS-1.3.
  37   * Added Raw Public Key (RFC7250) support.
  38   * Added support for certificate compression (RFC8879), including
  39     library support for Brotli and Zstandard compression.
  40   * Implemented support for all five instances of EdDSA from RFC8032.
  41   * Implemented SM4-XTS support.
  42   * Implemented deterministic ECDSA signatures (RFC6979) support.
  43   * Implemented AES-GCM-SIV (RFC8452) support.
  44   * Implemented Hybrid Public Key Encryption (HPKE) as defined in RFC9180.
  45   * Multiple new features and improvements of the CMP protocol support.
  46   * Subject or issuer names in X.509 objects are now displayed as UTF-8 strings
  47     by default.
  48   * TCP Fast Open (RFC7413) support is available on Linux, macOS, and FreeBSD
  49     where enabled and supported.
  50   * The default SSL/TLS security level has been changed from 1 to 2.

  53     provider this fully enables use of post-quantum/quantum-safe cryptography.
  54   * It is now possible to use the IANA standard names in TLS cipher
  55     configuration.

 227     PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
 228   * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
 229     SHA256, SHA384, SHA512 and Whirlpool digest functions have been
 230     deprecated.
 231   * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
 232     RC4, RC5 and SEED cipher functions have been deprecated.
