22 ### Major changes between OpenSSL 3.0 and OpenSSL 3.1 [under development]
24 * Subject or issuer names in X.509 objects are now displayed as UTF-8 strings
26 * TCP Fast Open (RFC7413) support is available on Linux, macOS, and FreeBSD
27 where enabled and supported.

37 as a fallback if that is still allowed by the property query.
39 ### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0.0
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).

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
