 whether 2.0.0 removes them depends on how future MCP spec revisions treat these features

 ## Tracking New Spec Revisions
 
 The SDK aims to support each new MCP specification revision, with the implementation timeline agreed per
 release based on feature complexity.
-Additive features from the 2026-07-28 revision (such as `server/discover`, multi round-trip requests,
-and the tasks extension) ship as opt-in functionality during 1.x. Breaking parts of that revision,
-such as the SEP-2575 stateless lifecycle rewrite, are reserved for 2.0.
+The 2026-07-28 revision shipped during 1.x: the server serves both lifecycle eras side by side,
+so the SEP-2575 stateless lifecycle (including `server/discover` and `subscriptions/listen`),
+SEP-2322 multi round-trip requests, SEP-2549 cache hints, and SEP-2243 custom headers are available alongside
+the legacy handshake. The few incompatible adjustments the revision required shipped in
+a minor release under the spec-conformance and security exceptions described in [VERSIONING.md](VERSIONING.md).
+Removing legacy-era support is reserved for a future major release.
+The tasks extension (SEP-2663) remains planned ([#391](https://github.com/modelcontextprotocol/ruby-sdk/issues/391)).
