Auto Translate JSON Library v2.1.0 Release Summary

🎯 Release Overview

Version: 2.1.0
Release Date: 2026-03-22
Type: Minor release with performance improvements and enhanced developer experience
Status: Ready for release

🚀 Key Features Added

1. Lazy Loading Performance Optimization

  • On-demand SDK loading: Translation engines load only when needed
  • Reduced startup time: Library imports in ~27ms (vs ~500ms loading all SDKs)
  • Lower memory footprint: Only selected engine's SDK loads into memory
  • Implementation: New provider-factory.ts with dynamic imports

2. LLM-Friendly CLI Enhancements

  • Structured JSON output: New --json flag for automation and LLM consumption
  • Enhanced help system: Comprehensive examples and engine documentation
  • Improved error messages: Helpful tips with links and configuration guidance
  • Better validation: Clear error messages for missing environment variables

3. Developer Experience Improvements

  • Updated documentation: All engines (huggingface, huggingface-local) fully documented
  • More examples: 15+ comprehensive usage patterns added
  • Local inference focus: Better documentation for huggingface-local and Ollama
  • Performance metrics: Execution timing in JSON output for monitoring

📊 Performance Benefits

Before v2.1.0:

  • All SDKs loaded at startup (~80MB+ memory)
  • Startup time: ~500ms
  • Memory: All translation SDKs in memory

After v2.1.0:

  • Only needed SDK loads on demand
  • Startup time: ~27ms (library import)
