+## [2.8.0] — 2026-03-19
+
+> Sprint: Bailian Coding Plan provider with editable base URLs, plus community contributions for Alibaba Cloud and Kimi Coding.
+
+### ✨ Features
+
+- **feat(providers)**: Added Bailian Coding Plan (`bailian-coding-plan`) — Alibaba Model Studio with Anthropic-compatible API. Static catalog of 8 models including Qwen3.5 Plus, Qwen3 Coder, MiniMax M2.5, GLM 5, and Kimi K2.5. Includes custom auth validation (400=valid, 401/403=invalid) (#467, @Mind-Dragon)
+- **feat(admin)**: Editable default URL in Provider Admin create/edit flows — users can configure custom base URLs per connection. Persisted in `providerSpecificData.baseUrl` with Zod schema validation rejecting non-http(s) schemes (#467)
+
+### 🧪 Tests
+
+- Added 30+ unit tests and 2 e2e scenarios for Bailian Coding Plan provider covering auth validation, schema hardening, route-level behavior, and cross-layer integration
+
+---
+
+## [2.7.10] — 2026-03-19
+
+> Sprint: Two new community-contributed providers (Alibaba Cloud Coding, Kimi Coding API-key) and Docker pino fix.
+
+### ✨ Features
+
+- **feat(providers)**: Added Alibaba Cloud Coding Plan support with two OpenAI-compatible endpoints — `alicode` (China) and `alicode-intl` (International), each with 8 models (#465, @dtk1985)
+- **feat(providers)**: Added dedicated `kimi-coding-apikey` provider path — API-key-based Kimi Coding access is no longer forced through OAuth-only `kimi-coding` route. Includes registry, constants, models API, config, and validation test (#463, @Mind-Dragon)
+
+### 🐛 Bug Fixes
+
+- **fix(docker)**: Added missing `split2` dependency to Docker image — `pino-abstract-transport` requires it at runtime but it was not being copied into the standalone container, causing `Cannot find module 'split2'` crashes (#459)
+
+---
+
+## [2.7.9] — 2026-03-18
+
+> Sprint: Codex responses subpath passthrough natively supported, Windows MITM crash fixed, and Combos agent schemas adjusted.
+
+### ✨ Features
+
+- **feat(codex)**: Native responses subpath passthrough for Codex — natively routes `POST /v1/responses/compact` to Codex upstream, maintaining Claude Code compatibility without stripping the `/compact` suffix (#457)
+
+### 🐛 Bug Fixes
+
+- **fix(combos)**: Zod schemas (`updateComboSchema` and `createComboSchema`) now include `system_message`, `tool_filter_regex`, and `context_cache_protection`. Fixes bug where agent-specific settings created via the dashboard were silently discarded by the backend validation layer (#458)
+- **fix(mitm)**: Kiro MITM profile crash on Windows fixed — `node-machine-id` failed due to missing `REG.exe` env, and the fallback threw a fatal `crypto is not defined` error. Fallback now safely and correctly imports crypto (#456)
+
+---
+
+## [2.7.8] — 2026-03-18
+
+> Sprint: Budget save bug + combo agent features UI + omniModel tag security fix.
+
+### 🐛 Bug Fixes
+
+- **fix(budget)**: "Save Limits" no longer returns 422 — `warningThreshold` is now correctly sent as fraction (0–1) instead of percentage (0–100) (#451)
+- **fix(combos)**: `<omniModel>` internal cache tag is now stripped before forwarding requests to providers, preventing cache session breaks (#454)
+
+### ✨ Features
+
+- **feat(combos)**: Agent Features section added to combo create/edit modal — expose `system_message` override, `tool_filter_regex`, and `context_cache_protection` directly from the dashboard (#454)
+
+---
+
+## [2.7.7] — 2026-03-18
+
+> Sprint: Docker pino crash, Codex CLI responses worker fix, package-lock sync.
+
+### 🐛 Bug Fixes
+
+- **fix(docker)**: `pino-abstract-transport` and `pino-pretty` now explicitly copied in Docker runner stage — Next.js standalone trace misses these peer deps, causing `Cannot find module pino-abstract-transport` crash on startup (#449)
+- **fix(responses)**: Remove `initTranslators()` from `/v1/responses` route — was crashing Next.js worker with `the worker has exited` uncaughtException on Codex CLI requests (#450)
+
+### 🔧 Maintenance
+
+- **chore(deps)**: `package-lock.json` now committed on every version bump to ensure Docker `npm ci` uses exact dependency versions
+
+---
+
+## [2.7.5] — 2026-03-18
+
+> Sprint: UX improvements and Windows CLI healthcheck fix.
+
+### 🐛 Bug Fixes
+
+- **fix(ux)**: Show default password hint on login page — new users now see `"Default password: 123456"` below the password input (#437)
+- **fix(cli)**: Claude CLI and other npm-installed tools now correctly detected as runnable on Windows — spawn uses `shell:true` to resolve `.cmd` wrappers via PATHEXT (#447)
+
+---
+
+## [2.7.4] — 2026-03-18
+
+> Sprint: Search Tools dashboard, i18n fixes, Copilot limits, Serper validation fix.
+
+### 🚀 Features
+
+- **feat(search)**: Add Search Playground (10th endpoint), Search Tools page with Compare Providers/Rerank Pipeline/Search History, local rerank routing, auth guards on search API (#443 by @Regis-RCR)
+  - New route: `/dashboard/search-tools`
+  - Sidebar entry under Debug section
+  - `GET /api/search/providers` and `GET /api/search/stats` with auth guards
+  - Local provider_nodes routing for `/v1/rerank`
+  - 30+ i18n keys in search namespace
+
+### 🐛 Bug Fixes
+
+- **fix(search)**: Fix Brave news normalizer (was returning 0 results), enforce max_results truncation post-normalization, fix Endpoints page fetch URL (#443 by @Regis-RCR)
+- **fix(analytics)**: Localize analytics day/date labels — replace hardcoded Portuguese strings with `Intl.DateTimeFormat(locale)` (#444 by @hijak)
+- **fix(copilot)**: Correct GitHub Copilot account type display, filter misleading unlimited quota rows from limits dashboard (#445 by @hijak)
+- **fix(providers)**: Stop rejecting valid Serper API keys — treat non-4xx responses as valid authentication (#446 by @hijak)
+
+---
+
+## [2.7.3] — 2026-03-18
+
+> Sprint: Codex direct API quota fallback fix.
+
+### 🐛 Bug Fixes
+
+- **fix(codex)**: Block weekly-exhausted accounts in direct API fallback (#440)
+  - `resolveQuotaWindow()` prefix matching: `"weekly"` now matches `"weekly (7d)"` cache keys
+  - `applyCodexWindowPolicy()` enforces `useWeekly`/`use5h` toggles correctly
+  - 4 new regression tests (766 total)
+
+---
+
+## [2.7.2] — 2026-03-18
+
+> Sprint: Light mode UI contrast fixes.
+
+### 🐛 Bug Fixes
+
+- **fix(logs)**: Fix light mode contrast in request logs filter buttons and combo badge (#378)
+  - Error/Success/Combo filter buttons now readable in light mode
+  - Combo row badge uses stronger violet in light mode
+
+---
+
+## [2.7.1] — 2026-03-17
+
+> Sprint: Unified web search routing (POST /v1/search) with 5 providers + Next.js 16.1.7 security fixes (6 CVEs).
+
+### ✨ New Features
+
+- **feat(search)**: Unified web search routing — `POST /v1/search` with 5 providers (Serper, Brave, Perplexity, Exa, Tavily)
+  - Auto-failover across providers, 6,500+ free searches/month
+  - In-memory cache with request coalescing (configurable TTL)
+  - Dashboard: Search Analytics tab in `/dashboard/analytics` with provider breakdown, cache hit rate, cost tracking
+  - New API: `GET /api/v1/search/analytics` for search request statistics
+  - DB migration: `request_type` column on `call_logs` for non-chat request tracking
+  - Zod validation (`v1SearchSchema`), auth-gated, cost recorded via `recordCost()`
+
+### 🔒 Security
+
+- **deps**: Next.js 16.1.6 → 16.1.7 — fixes 6 CVEs:
+  - **Critical**: CVE-2026-29057 (HTTP request smuggling via http-proxy)
+  - **High**: CVE-2026-27977, CVE-2026-27978 (WebSocket + Server Actions)
+  - **Medium**: CVE-2026-27979, CVE-2026-27980, CVE-2026-jcc7
