Version 0.5.7 - Critical Bug Fixes + Timeout Flexibility

This release fixes critical bugs and adds timeout configuration for better reliability.

BUG FIXES:
• Screenshot error handling - Errors during capture now properly report to Claude instead of being silently ignored
• Multi-agent coordination - Fixed race condition where multiple agents could claim the same reserved tab slot
• Message ID overflow protection - Replaced numeric IDs with UUIDs to eliminate collision risk

IMPROVEMENTS:
• Per-operation timeout support - All browser automation tools now accept optional timeout parameter (5s-300s range, default: 150s)
• Better error messages - Timeout errors now include operation name and duration for easier debugging

This is a stability and reliability update with no breaking changes. All existing functionality remains backward compatible.

Full changelog: https://github.com/boot-industries/claudezilla/blob/main/CHANGELOG.md

Autonomous installation, bug fixes, and multi-agent improvements.

New:
- Autonomous permissions — Installers auto-configure Claude Code settings and MCP server
- Expanded tab pool — 12 tabs shared across agents (up from 10)
- Screenshot purpose presets — quick-glance, read-text, inspect-ui, full-detail

Fixed:
- Tab ID type mismatch — Tab operations no longer fail with "Tab not found" on valid tabs
- Session cleanup on exit — Tabs are cleaned up immediately when a Claude session ends
- Mercy system slot reservation — Freed slots are now reserved for the waiting agent (30s
TTL)
- Request timeouts extended to 150s for long-running browser operations
- file:// URLs now allowed for local development
- Improved error messages for content script failures

v0.5.5 - Windows Support

New:
• Windows 10/11 support - Now works on Windows with named pipes for IPC
• Path security validation - Prevents injection attacks via null bytes and path traversal

Fixed:
• Support link in popup now opens correctly

Security:
• Environment variable validation for temp directories
• PowerShell installer uses safe JSON serialization

v0.5.4 - Security hardening + performance optimization

Security:
• Expression validation - firefox_evaluate now blocks dangerous patterns (fetch, eval, document.cookie,
localStorage, XMLHttpRequest)
• Agent ID truncation - Privacy-enhanced logging shows truncated IDs in all outputs
• Loop prompt sanitization - Preview field limited to 100 characters

Performance:
• Selector search optimization - 100 element limit per category with early exit
• Screenshot mutex timeout reduced from 5s to 3s for faster multi-agent feedback

v0.5.3: Reconnection resilience + diagnostics

Features:
• Auto-reconnect - Extension automatically reconnects when the native host disconnects (exponential backoff from 1s to 30s, max 10 attempts)
• New firefox_diagnose tool - Comprehensive connection health check that validates socket, auth token, and provides actionable fix recommendations
• MCP retry logic - Automatic retry with exponential backoff for transient connection failures

Improvements:
• Better error messages - Connection errors now show diagnostic info (socket/auth token state) with specific fix instructions
• Updated MCP SDK (0.5.0 → 1.25.2) for Claude Code 2.1.x compatibility

Bug fix:
- Fixed Support link to open https://claudezilla.com/support instead of local page
