## 🚀 What's New in v0.8.8-rc1

- **Agent run control:** Interrupt or steer an Agent mid-run, queue follow-up messages, and reclaim, edit, or escalate pending steers.
- **Human-in-the-loop Agents:** Agents stream question progress, ask up to four related questions in one form, pause for input or tool approval, and resume.
- **Unified Agent Builder:** A redesigned Tools marketplace brings together Skills, MCP, Code Interpreter, orchestration, Programmatic Tool Calling, model-spec controls, and per-tool background and intent settings.
- **Readable Agent activity:** Generated activity-group headers, parent phase summaries, and live tool intent labels make long reasoning and tool runs easier to scan.
- **Code Interpreter workflows:** Code and shell tools can run in the background, sandbox images return as viewable artifacts, and highly experimental stateful sessions can reuse prewarmed conversation workspaces.
- **Agent extensibility:** Experimental Agent Plugins can bundle deployment Skills, MCP servers, and opt-in command hooks, while explicit subagents initialize only when selected.
- **Memory, context, and identity:** Agents can manage memory with optional per-agent isolation, expose support contacts safely, and show a more faithful Context Usage gauge.
- **Sharing and files:** Shared conversations show a badge and update at a stable URL, while signed-in viewers can continue them as personal copies.
- **Artifact workflows:** Open previews fullscreen, work with PowerPoint `.potx` templates across upload, search, and code execution, upload shell scripts across common MIME variants, export Mermaid diagrams as SVG or PNG, and download original Office files from the artifact panel.
- **Models and reasoning:** Added GPT-5.6 with Responses API reasoning controls, Claude Opus 5 and Sonnet 5, Gemini 3.7 and 3.6 Flash, and Gemini 3.5 Flash-Lite.
- **Langfuse observability:** Configure encrypted Langfuse connections in-app, let authorized admins open sampled sessions directly, optionally fan out traces by tenant, and suppress central export per run.
- **Administration and security:** Delegate config sections, encrypt registered secrets, enforce SSRF checks for speech, OCR, and web tools, and generate unique temporary credentials when secrets are blank.
- **Messages and navigation:** Right-aligned user turns, unified multi-part editing, full-message copy, a dock-style message rail, virtualized search, smooth streaming, and faster Agent startup.
- **Streaming and tool reliability:** Adaptive provider smoothing, Redis delta batching, dynamic MCP tool refresh, parsed MCP response media types, runtime OAuth recovery, and Agent stream circuit breakers improve long-running workflows.
- **Deployment and reliability:** Added configurable HTTP timeouts, Amazon DocumentDB 5.0+ support, low-noise Redis and browser observabi
