🔐 Version 0.6.0

Released: August 27, 2025

New OAuth 2.0 Authentication System

• Added OAuth 2.0 Client Credentials Flow - Full implementation for VMware VVS (vSphere Vulnerabilities & Security) API access
• New OAuth Source Type - Dedicated source configuration with:
  • client_id - OAuth application identifier
  • client_secret - OAuth application secret
  • auth_url - Authentication endpoint URL
  • output_filename - Configurable output file names

Advanced HTTP Handling Improvements

• Automatic Redirect Handling - Up to 5 redirects automatically followed for OAuth requests
• Proper VVS API Headers - Includes required headers:
  • X-Vmw-Esp-Client - OAuth token authentication
• Enhanced Error Handling - Detailed OAuth-specific error messages and status reporting

File Handling Enhancements

• Raw File Downloads - OAuth downloads preserve original format without automatic decompression
• Smart Content Handling - Files downloaded in their native format (e.g., .gz files stay compressed)
• Configurable Output Names - Custom filenames for downloaded OAuth resources

Configuration Updates

New OAuth Example - Complete working example in sources.toml:

[[sources]]
url = "https://vvs.broadcom.com/v1/compatible/vcg/bundles/all?format=gz"
type = "OAuth"
client_id = "vsphere_hcllib"
client_secret = "cb65f5ac-cb38-4326-a48f-c0e8b23a2d38"
auth_url = "https://auth.esp.vmware.com/api/auth/v1/tokens"
output_filename = "vvs_data.gz"

Each platform release now includes:

• Main executable (DSvClient or DSvClient.exe)
• Complete configuration files:
  • config.toml - Main application configuration
  • sources.toml - Source definitions with OAuth examples
• Platform-specific README files with detailed setup instructions
• Ready-to-use packages - No additional configuration required (But a Broadcom Token)

🎯 Version 0.5.0

Released: August 27, 2025

Complete Command-Line Interface Overhaul (Major User Experience Update)

• Comprehensive help system - --help / -h flags show detailed usage information
• Auto-help display - Shows help when no arguments provided
• Professional CLI behavior - Matches industry standards for command-line tools

Enhanced Package Metadata

• Complete package information - Description, author, license, repository in Cargo.toml
• Runtime version access - Uses CARGO_PKG_VERSION at compile time
• Professional presentation - Clean, informative output format

Improved Argument Parsing

HTTP Error Response Enhancement (Major Feature)

• Detailed HTTP error messages - Captures actual server response bodies instead of generic status codes
• Enhanced DownloadReport structure - Stores HTTP error messages for 403/404 errors
• Better debugging information - Real server error responses help troubleshoot authentication and access issues

Advanced Timeout Management System

• Exponential backoff timeout tracking - Dynamic timeout adjustment based on network conditions
• Timeout escalation - Base 30s → Max 5min with doubling on failures
• Smart timeout reduction - Automatic timeout reduction after 5min of stability
• Connection health monitoring - Per-connection timeout tracking

Configuration System Improvements

• Enhanced config parsing - Better error handling for malformed configurations
• Expanded configuration options - More granular control over download behavior
• JSON export enhancements - HTTP error messages included in detailed reports

Retry Logic Overhaul

• Build stabilization - All tests passing and build successful
• Removed problematic Cargo.lock - Better dependency resolution

🗂️ Directory Structure Fixes

ESX_HOST Path Bug Resolution

• Fixed path extraction logic - Files no longer incorrectly saved under ESX_HOST directories
• Cleaner output structure - More intuitive directory organization

🛣️ Version 0.3.2 - Path Structure Overhaul

Released: August 18, 2025

Complete Path Extraction Rewrite

• Fixed malformed paths - Eliminated paths like /tmp/vmware/https:/dl.broadcom.com/...
• Enhanced extract_meaningful_path() function - Smart URL parsing that:
  • Filters out domain names and tokens
  • Skips generic segments (PROD, COMP)
  • Extracts meaningful paths like ESX_HOST/main, VCENTER/version
• Clean directory structures - Files now saved in logical paths like /tmp/vmware/ESX_HOST/main/

Documentation and Configuration Updates

• Added comprehensive README.md - 44 lines of documentation
• Enhanced sources.toml - Better examples and comments
