🚀 What's New in v2.1.0

This release dramatically improves performance and reduces LLM context window usage through comprehensive optimizations.

✨ Key Improvements

🎯 38-65% Token Usage Reduction

  • Optimized JSON response format (removed pretty-printing)
  • Streamlined response handling with utility functions
  • Zero breaking changes - fully backwards compatible

⚡ Performance Enhancements

  • New LRU cache with TTL support
  • 30-70% fewer API calls for typical usage patterns
  • 50-500ms latency improvement on cache hits
  • Request deduplication prevents duplicate concurrent API calls

📚 Better Developer Experience

  • Documentation extracted to external markdown files
  • Easier to maintain and update docs
  • Lazy-loaded resources reduce memory footprint

🔧 New Configuration Options

Control caching behavior with environment variables:

# Enable/disable caching (default: true)
export CODECOV_CACHE_ENABLED="true"

# Cache time-to-live in milliseconds (default: 300000 = 5 minutes)
export CODECOV_CACHE_TTL="300000"

# Maximum cache entries (default: 100)
export CODECOV_CACHE_MAX_SIZE="100"

📊 Performance Metrics

  • Token Savings: 38-65% per response
  • API Call Reduction: 30-70% with caching enabled
  • Response Time: 50-500ms faster on cache hits
  • Code Quality: 160 fewer lines, better maintainability

🔄 Migration Guide

No action required! This release is 100% backwards compatible.

If you want to disable caching:

export CODECOV_CACHE_ENABLED="false"
