 ## [Unreleased]
 
+## [1.7.0] - 2026-10-05
+
+This release lets a web application finish the OAuth authorization in the request that receives the redirect,
+bounds the `initialize` request a session retains and the resource URIs a `subscriptions/listen` stream retains,
+validates icons given as Hashes through `MCP::Icon`, and repairs two `subscriptions/listen` cases: a request that
+cannot be encoded is refused, and a removed stream is marked closed.
+The two bounds and the icon validation reject what earlier releases accepted and ship in a minor release under
+the exceptions described in [VERSIONING.md](VERSIONING.md); raise `max_initialize_request_bytes:` and
+`max_resource_subscription_bytes:` (or set them to `nil`) where the byte bounds are too tight, and give Hash icons only
+the `MCP::Icon` members with a valid `src`.
