v1.0.2

What's New

• Structural Browser Identity Detection: Proves legitimate browser windows via active WebSocket connection ownership (PID correlation across child processes and ancestors) plus expanded coverage for 16+ Chromium forks (Chromium, Chrome, Brave, Edge, Vivaldi, Opera, Helium, Zen, Cent, Thorium, Cromite, and more).
• Custom Browser Fork Support: Unlisted Chromium forks can now be recognized without modifying code via "extra_browser_classes" in ~/.config/tabcircle/config.json.
• SSRF & DNS-Rebind Hardening: Enhanced favicon validation with IP-level filtering and custom SNI pinning against loopback/private IP bypasses.
• Multi-Monitor Display Resolution: Multi-monitor screen targeting algorithm hardened and tested directly against real window coordinates and XRandR screens.
• WebSocket Reconnect Backoff & Battery Optimization: Exponential backoff reconnects on extension offscreen worker and reduced background idle polling.
• Packaging & CI Improvements: Linux release tarball unpacks into self-contained tabcircle-linux/, hardened GitHub Action SHA-pinning, and ensured clean Semgrep SAST compliance.
• Browser Extension Updated: Manifest bumped to v1.0.2. Reload unpacked from chrome://extensions after downloading.

System Requirements

• Linux: Python 3.9+, X11 session (Cinnamon, GNOME on Xorg, KDE, XFCE, MATE), Chromium-based browser (Chrome, Brave, Edge) 116+.
• macOS: macOS 14+ (Sonoma, Sequoia), Chromium-based browser 116+.
