+# Anycode v0.0.23
+
+This release updates the Agent Client Protocol (ACP) integration and fixes duplicate message bugs.
+
+## ACP Integration
+
+- Updated `agent-client-protocol` dependency to version `1.2.0` and `agent-client-protocol-schema` to version `1.4.0`.
+- Removed obsolete unstable features (`unstable_session_usage`, `unstable_session_close`, `unstable_session_resume`), aligning with the newly stabilized schema.
+- Updated schema-related imports and trait conversions in the Rust backend.
+
+## Frontend Chat Panel
+
+- Fixed a bug where user prompt messages (e.g. "куку") appeared twice in the chat history by ignoring the agent's echo `user_message_chunk` raw updates (as the client already registers and renders prompt submission immediately).
+
+**Full comparison:** `v0.0.22...v0.0.23`
