+## [Unreleased]
+

+
+## [3.12.3] - 2026-03-24
+
+Major release adding GitHub Copilot reverse proxy support, macOS code signing & Apple notarization, intelligent reasoning effort mapping for o-series models, skill backup/restore lifecycle, proxy gzip compression, and critical fixes for WebDAV password safety, tool message parsing, and dark mode.
+
+**Stats**: 36 commits | 107 files changed | +9,124 insertions | -802 deletions
+
+### Added
+
+- **GitHub Copilot Reverse Proxy**: Full GitHub Copilot integration as a Claude Code provider via OAuth Device Code flow; includes multi-account management, automatic token refresh, Anthropic ↔ OpenAI format conversion, real-time model list fetching, and usage statistics (#930)
+- **Copilot Auth Center**: New Auth Center panel in Settings for managing GitHub accounts globally, with per-provider account binding via `meta.authBinding`
+- **Tool Search Toggle**: Added `ENABLE_TOOL_SEARCH` env var support for Claude 2.1.76+; exposed as a checkbox in the provider Common Config editor (#930)
+- **Reasoning Effort Mapping**: Two-tier `resolve_reasoning_effort()` for OpenAI o-series and GPT-5+ models — explicit `output_config.effort` takes priority, falling back to thinking `budget_tokens` thresholds (<4 000→low, 4 000–16 000→medium, ≥16 000→high); covers both Chat Completions and Responses API paths with 17 unit tests
+- **OpenCode SQLite Backend**: Added SQLite session storage support for OpenCode alongside existing JSON backend; dual-backend scan with SQLite priority on ID conflicts, atomic session deletion, and path validation (#1401)
+- **Skill Auto-Backup**: Skill files are automatically backed up to `~/.cc-switch/skill-backups/` before uninstall, with metadata preserved in `meta.json`; old backups pruned to keep at most 20
+- **Skill Backup Restore & Delete**: Added list/restore/delete commands for skill backups; restore copies files back to SSOT, saves the DB record, and syncs to the current app with rollback on failure
+- **macOS Code Signing & Notarization**: CI now imports an Apple Developer ID certificate, signs the universal binary, submits for Apple notarization, and staples the ticket to both `.app` and `.dmg`; a hard-fail verification step (`codesign --verify` + `spctl -a` + `stapler validate`) gates the release for both artifacts
+- **Codex 1M Context Window Toggle**: One-click checkbox in Codex config editor to set `model_context_window = 1000000` with auto-populated `model_auto_compact_token_limit = 900000`; unchecking removes both fields
+- **Disable Auto-Upgrade Toggle**: Added `DISABLE_AUTOUPDATER` env var checkbox in the Claude Common Config editor to prevent Claude Code from auto-upgrading
+
+### Changed
+
+- **Skills Cache Strategy**: Replaced `invalidateQueries` with direct `setQueryData` updates for skill install/uninstall/import operations; added `staleTime: Infinity` with `keepPreviousData` to eliminate loading flicker (#1573)
+- **Proxy Gzip Compression**: Non-streaming proxy requests now auto-negotiate gzip compression instead of forcing `identity`; streaming requests conservatively keep `identity` to avoid SSE decompression errors
+- **o1/o3 Model Compatibility**: Chat Completions proxy forwarding now correctly uses `max_completion_tokens` instead of `max_tokens` for OpenAI o-series models such as o1/o3/o4-mini (#1451)
+- **OpenCode Model Variants**: Placed OpenCode model variants at top level instead of inside options for better discoverability (#1317)
+- **Skills Import Flow**: Replaced implicit filesystem-based app inference with explicit `ImportSkillSelection` to prevent incorrect multi-app activation; added reconciliation to remove disabled/orphaned symlinks and MCP servers from live config

+
+### Fixed
+
+- **WebDAV Password Silent Clear**: Fixed WebDAV password being silently wiped when ProviderList or UsageScriptModal saved settings by stripping `webdavSync` from frontend payloads and adding backend backfill logic in `merge_settings_for_save()` to preserve existing passwords
+- **Tool Message Parsing**: Fixed tool_use/tool_result message classification across Claude (tool_result content blocks), Codex (function_call/function_call_output payloads), and Gemini (array content + toolCalls extraction) session providers (#1401)
+- **Dark Mode Selector**: Changed Tailwind `darkMode` from `["selector", "class"]` to `["selector", ".dark"]` to ensure correct dark mode activation (#1596)
+- **Copilot Request Fingerprint**: Unified Copilot request fingerprint headers across all API call sites to prevent User-Agent leakage and stream check mismatches
+- **o-series Responses API Tokens**: Kept Responses API on the correct `max_output_tokens` field for o-series models instead of incorrectly injecting `max_completion_tokens`
+- **Provider Form Double Submit**: Prevented duplicate submissions on rapid button clicks in provider add/edit forms (#1352)
+- **Ghostty Session Restore**: Fixed Claude session restore in Ghostty terminal (#1506)
+- **Skill ZIP Import Extension**: Added `.skill` file extension support in ZIP import dialog (#1240, #1455)
+- **Skill ZIP Install Target App**: ZIP skill installs now use the currently active app instead of always defaulting to Claude

+- **Responsive Layout with TOC**: Improved responsive design when TOC title exists (#1491)
+- **Import Skills Dialog White Screen**: Added missing TooltipProvider in ImportSkillsDialog to prevent runtime crash when opening the dialog
+- **Panel Bottom Blank Area**: Replaced hardcoded `h-[calc(100vh-8rem)]` with `flex-1 min-h-0` across all content panels to eliminate bottom gap caused by mismatched offset values
+
+### Docs
+
+- **Pricing Model ID Normalization**: Added documentation section explaining model ID normalization rules (prefix stripping, suffix trimming, `@`→`-` replacement) in EN/ZH/JA user manuals (#1591)
+- **macOS Signed & Notarized**: Removed all `xattr` workaround instructions and "unidentified developer" warnings from README, README_ZH, installation guides (EN/ZH/JA), and FAQ pages (EN/ZH/JA); replaced with "signed and notarized by Apple" messaging

+
+## Overview
+
+CC Switch v3.12.3 is a major feature release that adds GitHub Copilot reverse proxy support with a dedicated Auth Center, introduces macOS code signing and Apple notarization for a seamless install experience, maps reasoning effort levels across providers, migrates OpenCode to a SQLite backend, enables Tool Search via the native `ENABLE_TOOL_SEARCH` environment variable toggle, and delivers a full skill backup/restore lifecycle. Additional improvements include proxy gzip compression, o-series model compatibility, Skills import rework, Ghostty terminal fix, Skills cache strategy optimization, Claude 4.6 context window update, and multiple bug fixes.
+
+**Release Date**: 2026-03-24
+
+**Update Scale**: 36 commits | 107 files changed | +9,124 / -802 lines
+
+---
+
+## Highlights
+
+- **GitHub Copilot reverse proxy**: Full Copilot proxy support with OAuth device flow authentication, token refresh, and request fingerprint emulation ([⚠️ Risk Notice](#️-risk-notice))
+- **Copilot Auth Center**: Dedicated authentication management UI for GitHub Copilot OAuth flow with token status display and one-click refresh
+- **macOS code signing & notarization**: macOS builds are now code-signed and notarized by Apple, eliminating the "unidentified developer" warning entirely
+- **Reasoning Effort mapping**: Proxy-layer auto-mapping — explicit `output_config.effort` takes priority, falling back to `budget_tokens` thresholds (<4 000→low, 4 000–16 000→medium, ≥16 000→high) for o-series and GPT-5+ models
+- **OpenCode SQLite backend**: Added SQLite session storage for OpenCode alongside existing JSON backend; dual-backend scan with SQLite priority on ID conflicts
+- **Codex 1M context window toggle**: One-click checkbox to set `model_context_window = 1000000` with auto-populated `model_auto_compact_token_limit`
+- **Disable Auto-Upgrade toggle**: Added `DISABLE_AUTOUPDATER` env var checkbox in the Claude Common Config editor to prevent Claude Code from auto-upgrading
+- **Tool Search env var toggle**: Tool Search enabled via Claude 2.1.76+ native `ENABLE_TOOL_SEARCH` environment variable in the Common Config editor — no binary patching required
+- **Skill backup/restore lifecycle**: Skills are automatically backed up before uninstall; backup list with restore and delete management added
+- **Proxy gzip compression**: Non-streaming proxy requests now auto-negotiate gzip compression, reducing bandwidth usage
+- **o-series model compatibility**: Chat Completions proxy correctly uses `max_completion_tokens` for o1/o3/o4-mini models; Responses API kept on the correct `max_output_tokens` field
+- **Skills import rework**: Replaced implicit filesystem-based app inference with explicit `ImportSkillSelection` to prevent incorrect multi-app activation
+- **Ghostty terminal support**: Fixed Claude session restore in Ghostty terminal
+
+---
+
+## New Features
+
+### GitHub Copilot Reverse Proxy
+
+Added full reverse proxy support for GitHub Copilot, enabling Copilot-authenticated requests to be forwarded through CC Switch.
+
+- Implements OAuth device flow authentication for GitHub Copilot
+- Automatic token refresh and session management
+- Request fingerprint emulation for seamless compatibility
+- Integrated into the existing proxy infrastructure alongside Claude, Codex, and Gemini handlers
+
+### Copilot Auth Center
+
+A dedicated authentication management UI for GitHub Copilot.
+
+- OAuth device flow with code display and browser-based authorization
+- Token status display showing expiration and validity
+- One-click token refresh without re-authentication
+- Integrated into the settings panel for easy access
+
+### Reasoning Effort Mapping
+
+Proxy-layer auto-mapping of reasoning effort for OpenAI o-series and GPT-5+ models.
+
+- Two-tier resolution: explicit `output_config.effort` takes priority, falling back to thinking `budget_tokens` thresholds (<4 000→low, 4 000–16 000→medium, ≥16 000→high)
+- Covers both Chat Completions and Responses API paths with 17 unit tests
+
+### OpenCode SQLite Backend
+
+Added SQLite session storage support for OpenCode alongside the existing JSON backend.
+
+- Dual-backend scan with SQLite priority on ID conflicts
+- Atomic session deletion and path validation
+- JSON backend remains functional for backwards compatibility
+
+### Codex 1M Context Window Toggle
+
+Added a one-click toggle for Codex 1M context window in the config editor.
+
+- Checkbox sets `model_context_window = 1000000` in `config.toml`
+- Auto-populates `model_auto_compact_token_limit = 900000` when enabled
+- Unchecking removes both fields cleanly
+
+### Disable Auto-Upgrade Toggle
+
+Added a checkbox in the Claude Common Config editor to disable Claude Code auto-upgrades.
+
+- Sets `DISABLE_AUTOUPDATER=1` in the environment configuration when enabled
+- Displayed alongside Teammates mode, Tool Search, and High Effort toggles
+
+### Tool Search Environment Variable Toggle
+
+Tool Search is now enabled via the native `ENABLE_TOOL_SEARCH` environment variable introduced in Claude 2.1.76+.
+
+- Toggle available in the Common Config editor under environment variables
+- Sets `ENABLE_TOOL_SEARCH=1` in the Claude environment configuration
+- No binary patching required — uses Claude's built-in support
+
+### macOS Code Signing & Notarization
+
+macOS builds are now code-signed and notarized by Apple.
+
+- Application signed with a valid Apple Developer certificate
+- Notarized through Apple's notarization service for Gatekeeper approval
+- DMG installer also signed and notarized
+- Eliminates the "unidentified developer" warning on first launch
+
+### Skill Auto-Backup on Uninstall
+
+Skill files are now automatically backed up before uninstall to prevent accidental data loss.
+
+- Backups stored in `~/.cc-switch/skill-backups/` with all skill files and a `meta.json` containing original metadata
+- Old backups are automatically pruned to keep at most 20
+- Backup path is returned to the frontend and shown in the success toast
+
+### Skill Backup Restore & Delete
+
+Added management commands for skill backups created during uninstall.
+
+- List all available skill backups with metadata
+- Restore copies files back to SSOT, saves the DB record, and syncs to the current app with rollback on failure
+- Delete removes the backup directory after a confirmation dialog
+- ConfirmDialog gains a configurable zIndex prop to support nested dialog stacking
+
+---
+
+## Changes
+
+### Skills Cache Strategy Optimization
+
+Optimized the Skills cache invalidation strategy for better performance.
+
+- Reduced unnecessary cache refreshes during skill operations
+- Improved cache coherence between skill install/uninstall and list queries
+
+### Claude 4.6 Context Window Update
+
+Updated Claude 4.6 model preset with the latest context window size.
+
+- Reflects the expanded context window for Claude 4.6 models
+- Updated in provider presets for accurate model information display
+
+### MiniMax M2.7 Upgrade
+
+- Updated MiniMax provider preset to M2.7 model variant
+
+### Xiaomi MiMo Upgrade
+
+- Updated Xiaomi MiMo provider preset to the latest model version
+
+### AddProviderDialog Simplification
+
+- Removed redundant OAuth tab, reducing dialog from 3 tabs to 2 (app-specific + universal)
+
+### Provider Form Advanced Options Collapse
+
+- Model mapping, API format, and other advanced fields in the Claude provider form now auto-collapse when empty
+- Auto-expands when any value is set or when a preset fills them in; does not auto-collapse when manually cleared
+
+### Proxy Gzip Compression
+
+Non-streaming proxy requests now support gzip compression for reduced bandwidth usage.
+
+- Non-streaming requests let reqwest auto-negotiate gzip and transparently decompress responses
+- Streaming requests conservatively keep `Accept-Encoding: identity` to avoid decompression errors on interrupted SSE streams
+
+### o1/o3 Model Compatibility
+
+Proxy forwarding now handles OpenAI o-series model token parameters correctly.
+
+- Chat Completions path uses `max_completion_tokens` instead of `max_tokens` for o1/o3/o4-mini models (#1451, thanks @Hemilt0n)
+- Responses API path kept on the correct `max_output_tokens` field instead of incorrectly injecting `max_completion_tokens`
+
+### OpenCode Model Variants
+
+- Placed OpenCode model variants at top level instead of inside options for better discoverability (#1317)
+
+### Skills Import Flow
+
+The Skills import flow has been reworked for correctness and cleanup.
+
+- Replaced implicit filesystem-based app inference with explicit `ImportSkillSelection` to prevent incorrect multi-app activation when the same skill directory exists under multiple app paths
+- Added reconciliation to `sync_to_app` to remove disabled/orphaned symlinks
+- MCP `sync_all_enabled` now removes disabled servers from live config
+- Schema migration preserves a snapshot of legacy app mappings to avoid lossy reconstruction
+
+---
+
+## Bug Fixes

+
+- Fixed dark mode rendering inconsistencies in UI components
+
+### Copilot Request Fingerprint
+
+- Fixed request fingerprint generation for Copilot proxy to match expected format
+
+### Provider Form Double Submit
+
+- Prevented duplicate submissions on rapid button clicks in provider add/edit forms (#1352, thanks @Hexi1997)
+
+### Ghostty Session Restore
+
+- Fixed Claude session restore in Ghostty terminal (#1506, thanks @canyonsehun)
+
+### Skill ZIP Import Extension
+
+- Added `.skill` file extension support in ZIP import dialog (#1240, #1455, thanks @yovinchen)
+
+### Skill ZIP Install Target App
+
+- ZIP skill installs now use the currently active app instead of always defaulting to Claude
+
+### OpenClaw Active Card Highlight
+

+## ⚠️ 风险提示
+
+**GitHub Copilot 反向代理免责声明**
+
+本版本新增的 Copilot 反向代理功能通过逆向工程的非官方 API 访问 GitHub Copilot 服务。启用此功能前，请注意以下风险：
+
+1. **违反服务条款**：此功能可能违反 [GitHub 可接受使用政策](https://docs.github.com/en/site-policy/acceptable-use-policies/github-acceptable-use-policies)和[附加产品条款](https://docs.github.com/en/site-policy/github-terms/github-terms-for-additional-products-and-features)，其中禁止过度自动化批量活动、未经授权的服务复制以及通过自动化手段对服务器施加不当负担。
+2. **账号风险**：已有类似工具的用户收到 GitHub 官方警告邮件，指出其存在"脚本化交互或其他刻意的异常或高强度使用"行为。收到警告后继续使用可能导致 Copilot 访问权限被暂停甚至永久封禁。
+3. **无法保证长期可用**：GitHub 可能随时更新其检测机制，当前可用的使用方式未来可能被标记。
+
+用户启用此功能即表示**自行承担所有风险**。CC Switch 不对因使用此功能而导致的任何账号限制、警告或服务暂停承担责任。
