+## [0.8.0] - 2026-10-19
+
+The alkcall 0.10.0 adoption: a dependency bump only — no source change
+in alktty. alkcall 0.10.0 is the gateway ownership seam release
+(`GatewayDispatch::with_ownership_provider`, the declared
+static-fallback opt-in, and the loud unwired-spine default). All of it
+touches surfacing alktty never uses: alktty consults the
+`OwnershipProvider` seam directly on its own paths (the direct-ALPN
+scope gate and the channels establisher), not through the gateway
+dispatch spine, and the wire surface and `OperationContext` shape are
+unchanged. The wire format, the direct-ALPN path, the `TtyBackend`
+trait, and alktty's public API surface are unchanged.
+
+### Changed
+
+- **BREAKING (ecosystem-coordination) — `alkcall` bumped to 0.10.0.**
+  alkcall 0.10.0 changed no type that alktty touches: the seam alktty
+  exercises (`ChannelCore`/`register_openable_with_establisher`/
+  `OpenEstablisher`/`OpenHandler`/`Establishment`, `ChannelClient`,
+  `OwnershipProvider`/`OwnershipStore`/`InMemoryOwnershipStore`) is
+  shape-identical to 0.9.0 — the loud unwired-spine default applies
+  only to `resource_type`-gated ops served through `GatewayDispatch`,
+  which alktty never registers against. alktty's public signatures
+  reference alkcall types, so downstream crates must now unify on
+  alkcall 0.10.0. Minor bump per the 0.x ecosystem-coordination rule
+  (raising the minimum requirement is breaking — hence 0.8.0, not a
+  patch release).
+- **`alkcall` requirement updated to `0.10.0`; lockfile bumped from
+  0.9.0 to 0.10.0.** Verification counts are unchanged from the 0.7.0
+  baseline (113 default / 137 all-features) — the adoption required no
+  source change in alktty.
