- 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.

- Control UI/settings+chat: add a browser-local personal identity for the operator (name plus local-safe avatar), route user identity rendering through the shared chat/avatar path used by assistant and agent surfaces, and tighten Quick Settings, agent fallback chips, and narrow-screen chat layouts so personalization no longer wastes space or clips controls. (#70362) Thanks @BunsDev.

- Gateway/diagnostics: enable payload-free stability recording by default and add a support-ready diagnostics export with sanitized logs, status, health, config, and stability snapshots for bug reports. (#70324) Thanks @gumadeiras.

- Agents/trajectory export: add default-on local trajectory capture plus `/export-trajectory` bundles with redacted transcripts, runtime events, prompts, metadata, and artifacts for reproducible debugging and dataset export. (#70291) Thanks @scoootscooob.

- Providers/Tencent: add the bundled Tencent Cloud provider plugin with TokenHub onboarding, docs, `hy3-preview` model catalog entries, and tiered Hy3 pricing metadata. (#68460) Thanks @JuniperSling.

- 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.

- 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.
