 ## [Unreleased]
 
+## [1.11.0] - 2026-10-30

+### Added
+
+- `acpremote` accepts a bearer token from a `bearer.<token>` WebSocket
+  subprotocol entry so browser clients that cannot set `Authorization` can
+  authenticate. The token is never echoed in the handshake response.

+- `acpremote` WebSocket servers negotiate the `acp.v1` subprotocol when a client
+  requests it, which browser clients such as acp-ui require. Clients that omit a
+  subprotocol remain supported.
