web-token/jwt-framework#734 adds the fully-specified Ed25519 and Ed448 algorithms, X448 for the ECDH-ES family, and deprecates EdDSA. The algorithm and curve tables gain the new entries with the PHP 8.4 note, the signature algorithms page gets a section with the three-step migration away from EdDSA, the key factory and console pages list the four OKP curves, the prerequisites say when sodium is still needed, the signed-token example moves to Ed25519, and the 4.2 → 4.3 guide carries the feature entry and the deprecation line.
