 - **feat(limits):** per-window quota cutoffs across all providers with usage data — operators can set per-quota-window thresholds (e.g. `session=95%, weekly=80%`) with cascading resolver (connection → provider default → global 98%) and zero-latency gate when nothing is configured. New migration 056, new `GET /api/providers/quota-windows` endpoint, and Dashboard › Limits cutoff modal. ([#2267](https://github.com/diegosouzapw/OmniRoute/pull/2267) — thanks @payne0420)
 - **feat(api-keys):** configurable default rate limits via `DEFAULT_RATE_LIMIT_PER_DAY` env var — replaces hardcoded 1000/day fallback with Zod-validated configuration while preserving secure defaults for existing deployments. ([#2266](https://github.com/diegosouzapw/OmniRoute/pull/2266) — thanks @gleber)
 - **feat(authz):** `managementPolicy` accepts API keys with `manage` scope — enables headless/programmatic management (provisioning providers, setting rate limits) without a browser session. ([#2265](https://github.com/diegosouzapw/OmniRoute/pull/2265) — thanks @gleber)
+- **feat(termux):** Android/Termux headless support — auto-detect Android platform for headless mode (no browser open), move `wreq-js` and `tls-client-node` to `optionalDependencies` for ARM compatibility, lazy-load WS proxy with graceful 503 when unavailable, set `GYP_DEFINES` for `better-sqlite3` ARM build, extended build timeout to 600s. ([#2273](https://github.com/diegosouzapw/OmniRoute/pull/2273) — thanks @t-way666)

 - **fix(guardrails/vision-bridge):** add `VISION_BRIDGE_BASE_URL` + `VISION_BRIDGE_API_KEY` env overrides so non-Anthropic vision-bridge calls can be routed through OmniRoute's own `/v1` self-loop, Google's Gemini OpenAI-compat endpoint, OpenRouter, or any other OpenAI-compatible URL — instead of being hardcoded to `https://api.openai.com/v1` (which failed with 401 for users without an OpenAI key, even when they configured `visionBridgeModel: "google/gemini-2.0-flash"`). Anthropic models keep their dedicated path. (#2232)
 - **docs(security):** document the ToS-violation hot spot of `ANTIGRAVITY_CREDITS=always` in `STEALTH_GUIDE.md`, including why it draws Google abuse detection more aggressively than free-tier-only usage and the recommended posture (`=retry`, Auto-Combo spread, per-connection RPM caps). (#2246)
 - **fix(settings):** default `debugMode` to `true` on fresh installations — the Debug sidebar section (Translator, Playground, Search Tools) was hidden on new installs because `debugMode` was not in the settings defaults object, making `data?.debugMode === true` evaluate to `false`. The toggle in System & Storage appeared active but had no effect until manually set. Now all sidebar sections are visible out of the box.
+- **fix(providers/command-code):** send required `skills` and `stream` payload fields — Command Code upstream wrapper now includes `skills: ""` and forces `params.stream: true` to align with upstream API requirements. Validation probe defaults to `deepseek/deepseek-v4-flash`. ([#2271](https://github.com/diegosouzapw/OmniRoute/pull/2271) — thanks @ddarkr)
+- **chore:** ignore `.playwright-mcp/` generated artifacts (CSP error logs, accessibility tree snapshots) — removes tracked test artifacts and adds the directory to `.gitignore`. ([#2269](https://github.com/diegosouzapw/OmniRoute/pull/2269) — thanks @backryun)
