Version 2.0.0 - Major Enhancement Release

🎉 Major Features Added

✅ Complete Get-MinIOObject Cmdlet Implementation

• Advanced Filtering: Filter by prefix, exact object name, or exclude directories
• Multi-Criteria Sorting: Sort by Name, Size, LastModified, or ETag (ascending/descending)
• Result Pagination: Limit results with MaxObjects parameter
• Version Support: Include object versions for versioned buckets
• Recursive Control: Toggle recursive vs non-recursive listing

✅ Enhanced Directory Management

• Automatic Directory Creation: BucketDirectory parameter creates nested structures automatically
• Explicit Folder Creation: New-MinIOFolder cmdlet for creating folder hierarchies
• Clean Directory Handling: Non-critical directory creation with graceful fallback
• Multi-Level Support: Support for complex nested directory structures (e.g., company/departments/engineering/teams/backend)

✅ Advanced Chunked Operations

• Configurable Chunk Sizes: 1MB minimum with intelligent size recommendations
• Multi-Layer Progress Tracking: Collection → File → Chunk progress reporting
• Performance Optimization: Optimal chunk sizes for different file sizes and network conditions
• Resume Capability Foundation: Infrastructure for future resume functionality

✅ Comprehensive Timing and Performance Metrics

• Duration Tracking: Precise timing for all upload/download operations
• Speed Reporting: Intelligent formatting (B/s, KB/s, MB/s, GB/s, TB/s)
• Performance Comparison: Built-in tools for comparing regular vs chunked operations
• Transfer Statistics: Detailed metrics for monitoring and optimization

🛠️ Issues Fixed

✅ Directory Creation Warnings

• Before: Disruptive WARNING: messages about "ObjectSize must be set"
• After: Clean VERBOSE: messages labeled as "Directory creation failed (non-critical)"
• Impact: Professional, clean logging that doesn't alarm users

✅ Missing Get-MinIOObject Cmdlet

• Before: Cmdlet referenced in documentation but didn't exist
• After: Full implementation with enterprise-grade filtering and sorting capabilities
• Impact: Complete object discovery and management functionality

✅ Threading and Progress Issues

• Fixed: PowerShell method calls from background threads
• Fixed: Array size limits for chunk generation
• Fixed: Progress reporting synchronization issues
