🚀 LibreChat v0.8.8

The v0.8.8 release of LibreChat

v0.8.8

What's Changed

Operator-facing YAML, environment, default, and migration changes are collected in Config v1.3.15, Config v1.3.16, and Config v1.3.17. This release uses Config 1.3.17, Helm chart 2.0.16, and the Agents SDK 4.0.0.

🏞️ Highlights

  • Meet Lia: Building LibreChat with LibreChat.
  • Agent control: Interrupt, steer, queue messages, answer questions, and approve tool calls.
  • Unified Agent Builder: Same-run Skill authoring, opt-in Programmatic Tool Calling, and background tools.
  • Background tasks: Clearer task cards, header controls, and automatic delivery of supported results.
  • Scheduled Chats: Cron, time zones, and Project destinations. In beta: experimental and disabled by default.
  • Code workspaces: Stateful sessions, attached machines, recovery, and guarded permissions. Highly experimental; compatible services required.
  • Beta Agents API: Improved compatibility with Chat Completions, Open Responses, Agent/Skill management, and introduced Agent Events
  • Experimental Agent Plugins: Bundle Skills and MCP servers, with opt-in command hooks.
  • Execution visibility: Live activity, tool timing, Context Usage, optional costs, and a configured Langfuse Trace Viewer.
  • Chat improvements: Draggable pins, chat filtering, manual compaction, mobile polish, and automatic attachment routing.
  • Model updates: GPT-6 and GPT-6.1 Sol, Claude Opus/Sonnet 5.5, and Gemini 3.8 Flash. GPT-6.1 Sol uses family-fallback limits and pricing.
  • Performance and security: Faster rendering and streaming and long-thread sends, stronger credential boundaries, tenant-scoped endpoints, and 2FA management limits.
