*Oliver Mihatsch*
+ * Added support for pluggable (provider-based) TLS signature algorithms.
+ This enables TLS 1.3 authentication operations with algorithms embedded
+ in providers not included by default in OpenSSL. In combination with
+ the already available pluggable KEM and X.509 support, this enables
+ for example suitable providers to deliver post-quantum or quantum-safe
+ cryptography to OpenSSL users.

+ *Michael Baentsch*

* Added support for Hybrid Public Key Encryption (HPKE) as defined
in RFC9180. HPKE is required for TLS Encrypted ClientHello (ECH),
Message Layer Security (MLS) and other IETF specifications.
