This week's release includes session history for external agents, agent panel restoration (so your threads survive editor restarts), thinking effort level controls for supported models, mermaid diagram support in markdown preview, and the option to include LSP document symbols in breadcrumbs and outline UI ("document_symbols": "on").
Features
AI
- ACP: Exposed session history for the following external agents: Auggie, Claude Agent, Codex, Factory Droid, Junie, Kimi CLI, Mistral Vibe, and OpenCode. (#49449)

Breaking Changes and Notices
- Agent: Removed deprecated GPT-4o, GPT-4.1, GPT-4.1-mini, and o4-mini models from OpenAI BYOK provider. (#49082)
