  23 ### Major changes between OpenSSL 3.1 and OpenSSL 3.2 [under development]
  24
  25   * Added client side support for QUIC.
  26   * Added multiple tutorials on the OpenSSL library and in particular
  27     on writing various clients (using TLS and QUIC protocols) with libssl.
  28   * Added support for Brainpool curves in TLS-1.3.
  29   * Added Raw Public Key (RFC7250) support.
  30   * Added support for certificate compression (RFC8879), including
  31     library support for Brotli and Zstandard compression.
  32   * Implemented support for all five instances of EdDSA from RFC8032.
  33   * Implemented SM4-XTS support.
  34   * Implemented deterministic ECDSA signatures (RFC6979) support.
  35   * Implemented AES-GCM-SIV (RFC8452) support.
  36   * Implemented Hybrid Public Key Encryption (HPKE) as defined in RFC9180.
  37   * Multiple new features and improvements of the CMP protocol support.
  38   * Subject or issuer names in X.509 objects are now displayed as UTF-8 strings
  39     by default.
  40   * TCP Fast Open (RFC7413) support is available on Linux, macOS, and FreeBSD
  41     where enabled and supported.
  42   * The default SSL/TLS security level has been changed from 1 to 2.

  44     operations as well as CMS and X.509 data structure support. With a suitable
  45     provider this fully enables use of post-quantum/quantum-safe cryptography.
  46   * It is now possible to use the IANA standard names in TLS cipher
  47     configuration.

 219     PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
 220   * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
 221     SHA256, SHA384, SHA512 and Whirlpool digest functions have been
 222     deprecated.
 223   * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
 224     RC4, RC5 and SEED cipher functions have been deprecated.
