🚀 Major Release: Leptos 0.8 Compatibility

This release brings full compatibility with Leptos 0.8 and significant improvements to the library's API, examples, and testing infrastructure.

✨ New Features

• Full Leptos 0.8 Support: Updated to work seamlessly with the latest Leptos framework
• Enhanced Type Safety: Improved type checking and compile-time error detection
• Modern Rust Standards: Updated to use latest Rust idioms and patterns

🔧 API Changes

• Query Hook Updates: use_query now expects QueryKey and a single async closure
• Signal Access: Result fields like is_loading, is_success, is_error, status are now Signals accessed via .get()
• Callback Invocation: refetch and mutate are now Callbacks invoked with .run()
• QueryKey Constructor: Updated to use QueryKey::new(&[...]) pattern

🧪 Testing & Examples

• Comprehensive Test Suite: All 28 tests now passing (12 core + 7 integration + 9 basic)
• Updated Examples: All examples updated to Leptos 0.8 and current API
• Working Benchmarks: Added performance benchmarks with criterion
• Integration Tests: Full integration test coverage for real-world usage patterns

📚 Documentation & Examples

• Updated Examples: basic_usage, advanced_usage, and basic examples all working
• API Documentation: Comprehensive coverage of all public APIs
• Migration Guide: Clear upgrade path from previous versions

🚀 Performance Improvements

• Benchmark Suite: Added performance measurement for key operations
• Query Key Operations: ~150-300ns for key creation and pattern matching
• Client Operations: ~20-900ns for client creation and cache operations
• Serialization: ~70-170ns for JSON/bincode operations

🔧 Technical Improvements

• Dependency Updates: Added criterion and rand for benchmarking
• Code Quality: Resolved all compilation errors and warnings
• Modern Standards: Updated deprecated function usage

📦 Breaking Changes

• Leptos 0.8 Required: This version requires Leptos 0.8 or higher
• API Updates: Several method signatures have changed for better type safety
• Signal Access: Result fields now require .get() for access

🎯 Migration Guide

To upgrade from 0.2.x to 0.3.0:

1. Update Leptos: Ensure you're using Leptos 0.8
2. Update Query Calls: Change use_query to use QueryKey::new(&[...])
3. Update Field Access: Add .get() to access result fields
4. Update Callbacks: Change .call() to .run() for refetch and mutate

🐛 Bug Fixes

• Fixed view! macro type compatibility issues
• Resolved lifetime issues in examples
• Fixed module path issues for client functions
• Corrected API compatibility across all components
