- **Cache Components:** Implemented dynamic cache components utilizing TDD.
- **UI & Customization:** Added custom favicon support, appearance tabs, wired whitelabeling to the sidebar, and added Windsurf guide steps across all 33 languages.
- **Log Retention:** Unified request log retention and artifacts natively.
- **Model Enhancements:** Added explicit `contextLength` for all opencode-zen models.
- **i18n & translations:** Integrated 33 language translations natively, including placeholder CI validations and Chinese documentation updates (#873, #869).

### 🐛 Bug Fixes

- **fix(mitm):** Compile MITM utilities as NodeNext ESM during prepublish, copy the CommonJS MITM server into the standalone artifact, and resolve MITM data paths without relying on Next.js aliases in packaged runtime.
- **fix(build):** Move the local `.tmp/wine32` Wine prefix out of the isolated Next.js build path so Windows Electron packaging artifacts cannot trigger `EACCES` scans during Node 24 builds.
- **fix(build):** Copy the `wreq-js` native runtime directory into the isolated Next.js standalone output so packaged Playwright/E2E starts can load the instrumentation hook on Linux.
- **fix(api):** Validate the Codex Responses websocket bridge and `/v1/batches` JSON payloads with Zod before use, keeping `request.json()` route validation green and returning explicit 400 responses for invalid bodies.
- **fix(providers):** Add explicit typing to provider alias and category helpers so the strict `typecheck:noimplicit:core` CI gate passes.
- **fix(ui):** Keep the upstream proxy provider detail page labeled with a fallback "Managed via Upstream Proxy Settings" management surface when translations are unavailable.
- **fix(electron):** Harden the production desktop CSP by removing `unsafe-eval` outside development and adding object, base URI, form action, frame ancestor, and worker restrictions.
- **fix(cli):** Replace shell-interpolated setup and privileged command execution paths with argument-based `spawn`/`execFile` helpers for database setup, Tailscale sudo commands, MITM DNS edits, and certificate install/uninstall flows.
- **fix(ui):** Keep provider icons resilient by using direct `@lobehub/icons` components first, then local PNG/SVG fallbacks, avoiding the `@lobehub/ui` peer runtime in the dashboard.

- **Qwen OAuth Mapping:** Reverted `id_token` reliance to `access_token` and enabled dynamic `resource_url` API endpoint injection for proper regional routing (#900).
- **Model Sync Engine:** Stored the strict internal Provider ID in `getCustomModels()` sync routines instead of the UI Channel Alias format, preventing SQLite catalog insertion failures (#903).
- **Claude Code & Codex:** Standardized non-streaming blank responses to Anthropic-formatted `(empty response)` to prevent CLI proxy crashes (#866).
- **CC Compatible Routing:** Resolved duplicate `/v1` endpoint collision during path concatenation for generic Claude Code gateways (#904).
- **Antigravity Dashboards:** Blocked unlimited quota models from falsely registering as exhausted `100% Usage` limit states in the Provider Usage UI (#857).
- **Claude Image Passthrough:** Fixed Claude models missing image block passthroughs (#898).
- **Gemini CLI Routing:** Resolved 403 authorization lockouts and content accumulation issues by refreshing the project ID via `loadCodeAssist` (#868).
- **Antigravity Stability:** Corrected model access lists, enforced 404 lockouts, fixed 429 cascades locking out standard connections, and capped `gemini-3.1-pro` output tokens (#885).
- **Provider Sync Cadence:** Repaired the provider limits synchronization cadence via the internal scheduler (#888).
- **Dashboard Optimization:** Resolved `/dashboard/limits` UI freezing when processing 70+ accounts via chunk parallelization (#784).
- **SSRF Hardening:** Enforced strict SSRF IP range filtering and blocked the `::1` loopback interface.
- **MIME Types:** Standardized `mime_type` to snake_case to match Gemini API specifications.
- **CI Stabilization:** Fixed failing analytics/settings Playwright selectors and request assertions so GitHub Actions E2E runs pass reliably across localized UIs and switch-based controls.
- **Deterministic Tests:** Removed date-sensitive quota fixtures from Copilot usage tests and aligned idempotency/model catalog tests with the merged runtime behavior.
- **MCP Type Hardening:** Removed zero-budget explicit `any` regressions from the MCP server tool registration path.
- **Model Sync Engine:** Bypassed destructive `replace` overrides when the provider's auto-sync yields an empty model list, maintaining stability for dynamic catalogs (#899).

### 🛠️ Maintenance

- **Pipeline Logging:** Refined pipeline logging artifacts and enforce retention caps (#880).
- **AGENTS.md Overhaul:** Condensed from 297→153 lines. Added build/test/style guidelines, code workflows (Prettier, TypeScript, ESLint), and trimmed verbose tables (#882).
- **Release Branch Integration:** Consolidated the active feature branches into `release/v3.4.2` on top of current `main` and validated the branch with lint, unit, coverage, build, and CI-mode E2E runs.
- **Testing:** Added vitest configuration for component testing and Playwright specs for settings toggles.
- **Doc Updates:** Expanded root readmes, translated chinese documents natively, and cleaned up obsolete files.
