🚀 BotBrowser 140 20250915

✨ What’s New

  • Chromium 140.0.7339.128 core — latest stable engine for performance & security.
  • Proxy engine rewrite — faster & more reliable. Unified config: use --proxy-server with auth + multi‑protocol (http/https/socks5). Old flags removed: --proxy-username, --proxy-password.

  • SOCKS5 DNS leak fix — ensures resolution goes through the proxy to avoid local DNS exposure.
  • New CLI: --proxy-ip (profile: configs.proxy.ip) — skip per‑page IP detection for faster opens; pair with --bot-config-timezone for region‑consistent sessions.
  • New CLI: --bot-config-mobile-force-touch (profile: configs.mobileForceTouch) — force touch events on/off when emulating mobile. Fixes #65.

📄 More details: CHANGELOG.md

🧭 Migration

Embed credentials in --proxy-server (or profile) instead of the removed flags. Examples:
http://user:pass@ip:port · socks5://user:pass@ip:port · socks5h://user:pass@ip:port
