+## [v1.36.0] - 2026-03-20
+
+This release adds WebSocket transport support for OpenAI streaming, introduces configurable tool call token limits, and improves the command-line interface with new session management capabilities.
+
+## What's New
+
+- Adds WebSocket transport option for OpenAI Responses API streaming as an alternative to SSE
+- Adds `/clear` command to reset current tab with a new session
+- Adds configurable `max_old_tool_call_tokens` setting in agent YAML to control historical tool call content retention
+
+## Improvements
+
+- Hides agent name header when stdout is not a TTY for cleaner piped output
+- Sorts all slash commands by label and hides `/q` alias from dialogs, showing only `/exit` and `/quit`
+- Injects `lastResponseID` as `previous_response_id` in WebSocket requests for better continuity
+
+## Bug Fixes
+
+- Fixes data race on WebSocket pool lazy initialization
+- Fixes panic in WebSocket handling
+
+## Technical Changes
+
+- Removes legacy `syncMessagesColumn` and messages JSON column from database schema
+- Simplifies WebSocket pool code structure
