 - Providers/Amazon Bedrock Mantle: add Claude Opus 4.7 through Mantle's Anthropic Messages route with provider-owned bearer-auth streaming, so the model is actually callable without treating AWS bearer tokens like Anthropic API keys. Thanks @wirjo.
 - OpenAI/Responses: use OpenAI's native `web_search` tool automatically for direct OpenAI Responses models when web search is enabled and no managed search provider is pinned; explicit providers such as Brave keep the managed `web_search` tool.
 - ACPX: add an explicit `openClawToolsMcpBridge` option that injects a core OpenClaw MCP server for selected built-in tools, starting with `cron`.
+- Agents/sessions: add mailbox-style `sessions_list` filters for label, agent, and search plus visibility-scoped derived title and last-message previews. (#69839) Thanks @dangoZhang.
 - Providers/GPT-5: move the GPT-5 prompt overlay into the shared provider runtime so compatible GPT-5 models receive the same behavior and heartbeat guidance through OpenAI, OpenRouter, OpenCode, Codex, and other GPT providers; add `agents.defaults.promptOverlays.gpt5.personality` as the global friendly-style toggle while keeping the OpenAI plugin setting as a fallback.
 - Providers/xAI: add image generation, text-to-speech, and speech-to-text support, including `grok-imagine-image` / `grok-imagine-image-pro`, reference-image edits, six live xAI voices, MP3/WAV/PCM/G.711 TTS formats, `grok-stt` audio transcription, and xAI realtime transcription for Voice Call streaming. (#68694) Thanks @KateWilkins.
 - Models/commands: add `/models add <provider> <modelId>` so you can register a model from chat and use it without restarting the gateway; keep `/models` as a simple provider browser while adding clearer add guidance and copy-friendly command examples. (#70211) Thanks @Takhoffman.
