Enhanced Developer Experience and Cross-Platform Support

Container Use v0.4.0 brings streamlined command workflows, native Windows support, and a powerful new
editing tool that reduces context rot for complex coding tasks.

Key Improvements

Context-Preserving File Editing

• New environment_file_edit tool enables efficient find-and-replace operations
• Massively reduces context rot during complex coding tasks by allowing targeted edits without full file
  rewrites

Smarter Command Interface

• Commands like log, checkout, diff, and inspect now work without mandatory arguments with interactive
  environment selection
• Improved positional argument handling across all subcommands

Cross-Platform Support

• Native Windows support with proper signal handling
• Fixed Unicode marshalling issues

Additional Features

• Environment secrets support in services
• Streamlined documentation (42% reduction in complexity)
• Improved environment state management
