 - Basic provider management
 - Claude Code integration
 - Configuration file handling
-
-## [Unreleased]
-
-### ⚠️ Breaking Changes
-
-- **Runtime auto-migration from v1 to v2 config format has been removed**
-  - `MultiAppConfig::load()` no longer automatically migrates v1 configs
-  - When a v1 config is detected, the app now returns a clear error with migration instructions
-  - **Migration path**: Install v3.2.x to perform one-time auto-migration, OR manually edit `~/.cc-switch/config.json` to v2 format
-  - **Rationale**: Separates concerns (load() should be read-only), fail-fast principle, simplifies maintenance
-  - Related: `app_config.rs` (v1 detection improved with structural analysis), `app_config_load.rs` (comprehensive test coverage added)
-
-- **Legacy v1 copy file migration logic has been removed**
-  - Removed entire `migration.rs` module (435 lines) that handled one-time migration from v3.1.0 to v3.2.0
-  - No longer scans/merges legacy copy files (`settings-*.json`, `auth-*.json`, `config-*.toml`)
-  - No longer archives copy files or performs automatic deduplication
-  - **Migration path**: Users upgrading from v3.1.0 must first upgrade to v3.2.x to automatically migrate their configurations
-  - **Benefits**: Improved startup performance (no file scanning), reduced code complexity, cleaner codebase
-
-- **Tauri commands now only accept `app` parameter**
-  - Removed legacy `app_type`/`appType` compatibility paths
-  - Explicit error with available values when unknown `app` is provided
-
-### 🔧 Improvements
-
-- Unified `AppType` parsing: centralized to `FromStr` implementation, command layer no longer implements separate `parse_app()`, reducing code duplication and drift
-- Localized and user-friendly error messages: returns bilingual (Chinese/English) hints for unsupported `app` values with a list of available options
-- Simplified startup logic: Only ensures config structure exists, no migration overhead
-
-### 🧪 Tests
-
-- Added unit tests covering `AppType::from_str`: case sensitivity, whitespace trimming, unknown value error messages
-- Added comprehensive config loading tests:
-  - `load_v1_config_returns_error_and_does_not_write`
-  - `load_v1_with_extra_version_still_treated_as_v1`
-  - `load_invalid_json_returns_parse_error_and_does_not_write`
-  - `load_valid_v2_config_succeeds`

+# CC Switch v3.9.0
+
+> Local API Proxy, Auto Failover, Universal Provider, and a more complete multi-app workflow
+
+**[中文版 →](release-note-v3.9.0-zh.md) | [日本語版 →](release-note-v3.9.0-ja.md)**
+
+---
+
+## Overview
+
+CC Switch v3.9.0 is the stable release of the v3.9 beta series (`3.9.0-1`, `3.9.0-2`, `3.9.0-3`).
+It introduces a local API proxy with per-app takeover, automatic failover, universal providers, and many stability and UX improvements across Claude Code, Codex, and Gemini CLI.
+
+**Release Date**: 2026-01-07
+
+---
+
+## Highlights
+
+- Local API Proxy for Claude Code / Codex / Gemini CLI
+- Auto Failover with circuit breaker and per-app failover queues
+- Universal Provider: one shared config synced across apps (ideal for API gateways like NewAPI)
+- Skills improvements: multi-app support, unified management with SSOT + React Query
+- Common config snippets: extract reusable snippets from the editor or the current provider
+- MCP import: import MCP servers from installed apps
+- Usage improvements: auto-refresh, cache hit/creation metrics, and timezone fixes
+- Linux packaging: RPM and Flatpak artifacts
+
+---
+
+## Major Features
+
+### Local API Proxy
+
+- Runs a local high-performance HTTP proxy server (Axum-based)
+- Supports Claude Code, Codex, and Gemini CLI with a unified proxy
+- Per-app takeover: you can independently decide which app routes through the proxy
+- Live config takeover: backs up and redirects the CLI live config to the local proxy when takeover is enabled
+- Monitoring: request logging and usage statistics for easier debugging and cost tracking
+- Error request logging: keep detailed logs for failed proxy requests to simplify debugging (#401, thanks @yovinchen)
+
+### Auto Failover (Circuit Breaker)
+
+- Automatically detects provider failures and triggers protection (circuit breaker)
+- Automatically switches to a backup provider when the current one is unhealthy
+- Tracks provider health in real time, and keeps independent failover queues per app
+- When failover is disabled, timeout/retry related settings no longer affect normal request flow
+
+### Skills Management
+
+- Multi-app Skills support for Claude Code and Codex, with smoother migration from older skill layouts (#365, #378, thanks @yovinchen)
+- Unified Skills management architecture (SSOT + React Query) for more consistent state and refresh behavior
+- Better discovery UX and performance:
+  - Skip hidden directories during discovery
+  - Faster discovery with long-lived caching for discoverable skills
+  - Clear loading indicators and more discoverable header actions (import/refresh)
+  - Fix wrong skill repo branch (#505, thanks @kjasn)
+
+### Universal Provider
+
+- Add a shared provider configuration that can sync to Claude/Codex/Gemini (#348, thanks @Calcium-Ion)
+- Designed for API gateways that support multiple protocols (e.g., NewAPI)
+- Allows per-app default model mapping under a single provider
+
+### Common Config Snippets (Claude/Codex/Gemini)
+
+- Maintain a reusable "common config" snippet and merge/append it into providers that enable it
+- New extraction workflow:
+  - Extract from the editor content (what you are currently editing)
+  - Or extract from the current active provider when the editor content is not provided
+- Codex extraction is safer:
+  - Removes provider-specific sections like `model_provider`, `model`, and the entire `model_providers` table
+  - Preserves `base_url` under `[mcp_servers.*]` so MCP configs are not accidentally broken
+
+### MCP Management
+
+- Import MCP servers from installed apps
+- Improve robustness: skip sync when the target CLI app is not installed; handle invalid Codex `config.toml` gracefully (#461, thanks @majiayu000)
+- Windows compatibility: wrap npx/npm commands with `cmd /c` for MCP export
+
+### Usage & Pricing
+
+- Usage & pricing improvements: auto-refresh, cache hit/creation metrics, timezone handling fixes, and refreshed built-in pricing table (#508, thanks @yovinchen)
+- DeepLink support: import usage query configuration via deeplink (#400, thanks @qyinter)
+- Model extraction for usage statistics (#455, thanks @yovinchen)
+- Usage query credentials can fall back to provider config (#360, thanks @Sirhexs)
+
+---
+
+## UX Improvements
+
+- Provider search filter: quickly find providers by name (#435, thanks @TinsFox)
+- Provider icon colors: customize provider icon colors for quicker visual identification (#385, thanks @yovinchen)
+- Keyboard shortcut: `Cmd/Ctrl + ,` opens Settings (#436, thanks @TinsFox)
+- Skip Claude Code first-run confirmation dialog (optional)
+- Closable toasts: close buttons for switch toast and all success toasts (#350, thanks @ForteScarlet)
+- Update badge navigation: clicking the update badge opens the About tab
+- Settings page tab style improvements (#342, thanks @wenyuanw)
+- Smoother transitions: fade transitions for app/view switching and exit animations for panels
+- Proxy takeover active theme: apply an emerald theme while takeover is active
+- Dark mode readability improvements for forms and labels
+- Better window dragging area for full-screen panels (#525, thanks @zerob13)
+
+---
+
+## Platform Notes
+
+### Windows
+
+- Prevent terminal windows from appearing during version checks
+- Improve window sizing defaults (minimum width/height)
+- Fix black screen on startup by using the system titlebar
+- Add a fallback for `crypto.randomUUID()` on older WebViews
+
+### macOS
+
+- Use `.app` bundle path for autostart to avoid terminal window popups (#462, thanks @majiayu000)
+- Improve tray/icon behavior and header alignment
+
+---
+
+## Packaging
+
+- Linux: RPM and Flatpak packaging targets are now available for building release artifacts
+
+---
+
+## Notes
+
+- Security improvements for the JavaScript executor and usage script execution (#151, thanks @luojiyin1987).
+- SQL import is restricted to CC Switch exported backups to reduce the risk of importing unsafe or incompatible SQL dumps.
+- Proxy takeover modifies CLI live configs; CC Switch will back up the live config before redirecting it to the local proxy. If you want to revert, disable takeover/stop the proxy and restore from the backup when needed.
