Release v0.6.7

Added

• Parallel Workflow Execution - Major performance improvement for update process
  • Added -Parallel switch to enable concurrent downloads and installations
  • Config and App downloads/installs run simultaneously instead of sequentially
  • Miniserver updates process concurrently with configurable concurrency limits
  • ThreadJob-based architecture for efficient resource utilization
  • Automatic fallback to sequential mode if issues detected
• Enhanced Progress Tracking for Parallel Mode
  • Component-specific progress bars (Config, App, Miniservers)
  • Real-time download speeds and remaining time per component
  • Elapsed time tracking with proper timer display (⏱️ mm:ss format)
  • Weighted miniserver progress calculation (Init=0, Update=2, Reboot=3, Wait=4, Complete=5)
  • Status symbols for miniserver stages (🔍🔄🚀⏳✓✗)
• Configuration File Support - UpdateLoxone.config.json
  • UseParallelExecution - Enable parallel mode by default
  • MaxConcurrency - Control download/install concurrency
  • MaxMSConcurrency - Control miniserver update concurrency
  • Command-line switches override configuration settings
• Console Progress Display - Alternative to toast notifications
  • ASCII progress bars for non-toast environments
  • Real-time updates with component status
  • Individual miniserver status tracking
  • Automatic fallback when toast notifications unavailable
• Thread-Safe State Management
  • New LoxoneUtils.ThreadSafe module with mutex-protected operations
  • Update-WorkflowState for safe concurrent state updates
  • Get-WorkflowState for consistent state reads across threads
  • Named mutex for cross-process synchronization

Changed

• Progress Worker Architecture
  • Separated progress tracking into dedicated worker thread
  • Prevents UI freezing during heavy operations
  • Maintains toast data binding throughout workflow
  • Graceful shutdown with proper cleanup
• Enhanced Logging
  • Comprehensive parallel mode detection logging
  • Thread/job lifecycle tracking
  • Performance metrics for concurrent operations
  • Debug traces for troubleshooting parallel issues

Fixed

• Toast Notification Issues in Parallel Mode
  • Fixed progress bars resetting to 0% when Config completes
  • Fixed App timer showing incorrect values after Config finishes
  • Fixed "Waiting..." status during file validation (now shows "Checking existing files...")
  • Fixed timer not starting until installation begins
  • Fixed toast updates from main script interfering with progress worker
• Threading Issues
  • Fixed ThreadJob pool exhaustion with proper cleanup
  • Fixed Ctrl+C handler to stop all worker threads
  • Fixed environment variable scope issues in finally blocks
  • Fixed race conditions between worker threads
