## What changed - Update the `rmcp` model and transport integrations for `3.0.0-beta.3`. - Preserve legacy `elicitation/create` form requests, schema defaults, metadata, and wire-format compatibility while adopting the new elicitation types. - Harden OAuth discovery by using GET-first discovery without starting an MCP session, preventing cross-origin header redirects, validating authorization-server and callback issuers, and retaining compatibility with metadata that omits an issuer. - Keep stored OAuth credentials readable and avoid requiring reauthorization after transient refresh failures. ## Testing - Add coverage for legacy elicitation round trips, OAuth discovery variants, callback issuer validation, credential migration, and refresh failures.
