 ## [Unreleased]

+## [2.5.0] - 2026-03-14
+
+> Major release: strict-random routing strategy, API key access controls, connection groups, external pricing sync, and critical bug fixes for thinking models, combo testing, and tool name validation.
+
+### ✨ New Features (PRs #363 & #365)
+
+- **Strict-Random Routing Strategy**: Fisher-Yates shuffle deck with anti-repeat guarantee and mutex serialization for concurrent requests. Independent decks per combo and per provider.
+- **API Key Access Controls**: `allowedConnections` (restrict which connections a key can use), `is_active` (enable/disable key with 403), `accessSchedule` (time-based access control), `autoResolve` toggle, rename keys via PATCH.
+- **Connection Groups**: Group provider connections by environment. Accordion view in Limits page with localStorage persistence and smart auto-switch.
+- **External Pricing Sync (LiteLLM)**: 3-tier pricing resolution (user overrides → synced → defaults). Opt-in via `PRICING_SYNC_ENABLED=true`. MCP tool `omniroute_sync_pricing`. 23 new tests.
+- **i18n**: 30 languages updated with strict-random strategy, API key management strings. pt-BR fully translated.
+
+### 🐛 Bug Fixes
+
+- **fix #355**: Stream idle timeout increased from 60s to 300s — prevents aborting extended-thinking models (claude-opus-4-6, o3, etc.) during long reasoning phases. Configurable via `STREAM_IDLE_TIMEOUT_MS`.
+- **fix #350**: Combo test now bypasses `REQUIRE_API_KEY=true` using internal header, and uses OpenAI-compatible format universally. Timeout extended from 15s to 20s.
+- **fix #346**: Tools with empty `function.name` (forwarded by Claude Code) are now filtered before upstream providers receive them, preventing "Invalid input[N].name: empty string" errors.
+
+### 🗑️ Closed Issues
+
+- **#341**: Debug section removed — replacement is `/dashboard/logs` and `/dashboard/health`.
+
+> API Key Round-Robin support for multi-key provider setups, and confirmation of wildcard routing and quota window rolling already in place.
+
+### ✨ New Features
+
+- **API Key Round-Robin (T07)**: Provider connections can now hold multiple API keys (Edit Connection → Extra API Keys). Requests rotate round-robin between primary + extra keys via `providerSpecificData.extraApiKeys[]`. Keys are held in-memory indexed per connection — no DB schema changes required.
+
+### 📝 Already Implemented (confirmed in audit)
+
+- **Wildcard Model Routing (T13)**: `wildcardRouter.ts` with glob-style wildcard matching (`gpt*`, `claude-?-sonnet`, etc.) is already integrated into `model.ts` with specificity ranking.
+- **Quota Window Rolling (T08)**: `accountFallback.ts:isModelLocked()` already auto-advances the window — if `Date.now() > entry.until`, lock is deleted immediately (no stale blocking).
+
+> UI polish, routing strategy additions, and graceful error handling for usage limits.
+
+### ✨ New Features
+
+- **Fill-First & P2C Routing Strategies**: Added `fill-first` (drain quota before moving on) and `p2c` (Power-of-Two-Choices low-latency selection) to combo strategy picker, with full guidance panels and color-coded badges.
+- **Free Stack Preset Models**: Creating a combo with the Free Stack template now auto-fills 7 best-in-class free provider models (Gemini CLI, Kiro, iFlow×2, Qwen, NVIDIA NIM, Groq). Users just activate the providers and get a $0/month combo out-of-the-box.
+- **Wider Combo Modal**: Create/Edit combo modal now uses `max-w-4xl` for comfortable editing of large combos.
+
+### 🐛 Bug Fixes
+
+- **Limits page HTTP 500 for Codex & GitHub**: `getCodexUsage()` and `getGitHubUsage()` now return a user-friendly message when the provider returns 401/403 (expired token), instead of throwing and causing a 500 error on the Limits page.
+- **MaintenanceBanner false-positive**: Banner no longer shows "Server is unreachable" spuriously on page load. Fixed by calling `checkHealth()` immediately on mount and removing stale `show`-state closure.
+- **Provider icon tooltips**: Edit (pencil) and delete icon buttons in the provider connection row now have native HTML tooltips — all 6 action icons are now self-documented.
+
+> Multiple improvements from community issue analysis, new provider support, bug fixes for token tracking, model routing, and streaming reliability.
+
+### ✨ New Features
+
+- **Task-Aware Smart Routing (T05)**: Automatic model selection based on request content type — coding → deepseek-chat, analysis → gemini-2.5-pro, vision → gpt-4o, summarization → gemini-2.5-flash. Configurable via Settings. New `GET/PUT/POST /api/settings/task-routing` API.
+- **HuggingFace Provider**: Added HuggingFace Router as an OpenAI-compatible provider with Llama 3.1 70B/8B, Qwen 2.5 72B, Mistral 7B, Phi-3.5 Mini.
+- **Vertex AI Provider**: Added Vertex AI (Google Cloud) provider with Gemini 2.5 Pro/Flash, Gemma 2 27B, Claude via Vertex.
+- **Playground File Uploads**: Audio upload for transcription, image upload for vision models (auto-detect by model name), inline image rendering for image generation results.
+- **Model Select Visual Feedback**: Already-added models in combo picker now show ✓ green badge — prevents duplicate confusion.
+- **Qwen Compatibility (PR #352)**: Updated User-Agent and CLI fingerprint settings for Qwen provider compatibility.
+- **Round-Robin State Management (PR #349)**: Enhanced round-robin logic to handle excluded accounts and maintain rotation state correctly.
+- **Clipboard UX (PR #360)**: Hardened clipboard operations with fallback for non-secure contexts; Claude tool normalization improvements.
+
+### 🐛 Bug Fixes
+
+- **Fix #302 — OpenAI SDK stream=False drops tool_calls**: T01 Accept header negotiation no longer forces streaming when `body.stream` is explicitly `false`. Was causing tool_calls to be silently dropped when using the OpenAI Python SDK in non-streaming mode.
+- **Fix #73 — Claude Haiku routed to OpenAI without provider prefix**: `claude-*` models sent without a provider prefix now correctly route to the `antigravity` (Anthropic) provider. Added `gemini-*`/`gemma-*` → `gemini` heuristic as well.
+- **Fix #74 — Token counts always 0 for Antigravity/Claude streaming**: The `message_start` SSE event which carries `input_tokens` was not being parsed by `extractUsage()`, causing all input token counts to drop. Input/output token tracking now works correctly for streaming responses.
+- **Fix #180 — Model import duplicates with no feedback**: `ModelSelectModal` now shows ✓ green highlight for models already in the combo, making it obvious they're already added.
+- **Media page generation errors**: Image results now render as `<img>` tags instead of raw JSON. Transcription results shown as readable text. Credential errors show an amber banner instead of silent failure.
+- **Token refresh button on provider page**: Manual token refresh UI added for OAuth providers.
+
+### 🔧 Improvements
+
+- **Provider Registry**: HuggingFace and Vertex AI added to `providerRegistry.ts` and `providers.ts` (frontend).
+- **Read Cache**: New `src/lib/db/readCache.ts` for efficient DB read caching.
+- **Quota Cache**: Improved quota cache with TTL-based eviction.
+
+### 📦 Dependencies
+
+- `dompurify` → 3.3.3 (PR #347)
+- `undici` → 7.24.2 (PR #348, #361)
+- `docker/setup-qemu-action` → v4 (PR #342)
