Full Release Notes

## Stealth Chromium Build

Pre-built Chromium 145 with 25 source-level C++ fingerprint patches. First v145 binary release.

See the full [CHANGELOG](https://github.com/CloakHQ/CloakBrowser/blob/main/CHANGELOG.md) for details.

### What's New

**Binary (from v142)**
- **Chromium 145** — latest stable base (up from 142)
- **25 fingerprint patches** (up from 16) — fingerprint randomization across more browser APIs
- **Full stealth audit** — every patch reviewed for detection vectors, multiple fixes shipped
- **CDP hardening** — audited and patched known automation detection vectors
- **New runtime flags** for finer control over fingerprint behavior
- **Zero regressions** from v142, plus fixes for detection vectors that v142 left exposed

**Wrapper (v0.3.0)**
- **Patchright integration** — CDP stealth built-in, reduces Playwright's automation footprint
- **SHA-256 checksum verification** — binary downloads verified for integrity
- **GitHub Releases fallback** — auto-fallback if primary mirror is unavailable
- **GeoIP auto-detect** — `launch(proxy="...", geoip=True)` sets timezone and locale from proxy IP
- **Realistic viewport** — `launch_context()` defaults to 1920×947 (maximized Chrome on 1080p)
- **Per-platform versioning** — Linux gets v145, macOS stays on v142 until v145 Mac builds are ready

### Test Results
- 40/40 matrix tests (Core Stealth, Fingerprint Noise, Bot Detection, reCAPTCHA, Headers & TLS)
- 6/6 Turnstile/CAPTCHA tests (reCAPTCHA Enterprise 0.7-0.9, Turnstile managed + non-interactive)
- 17/17 flag toggle tests (all flags verified with and without)
- bot.sannysoft.com 56/56, BrowserScan 19/0 abnormal, CreepJS headless: 0%

### Install
```bash
pip install cloakbrowser    # Python
npm install cloakbrowser    # JavaScript
# Binary auto-downloads on first launch
```

### Breaking Changes
- Python: dependency changed from `playwright` to `patchright` (API-compatible — `cloakbrowser.launch()` handles this automatically)
- `launch_context()` viewport default changed from 1280×720 to 1920×947
