# Version 0.6.0 Release Notes
**Release Date**: October 12, 2025
## Overview
Version 0.6.0 is a version alignment release with no breaking changes. All features from v0.5.0 remain fully functional.
## Version Updates
All crates have been bumped to v0.6.0:
- ✅ `rust-queries-builder` → **0.6.0**
- ✅ `rust-queries-core` → **0.6.0**
- ✅ `rust-queries-derive` → **0.6.0**
## What's Included
This release includes all the powerful features introduced in v0.5.0:
### 🎯 Extension Trait (`QueryExt`)
Call `.query()` and `.lazy_query()` directly on containers:
```rust
use rust_queries_builder::QueryExt;
let products = vec![/* ... */];
// Ergonomic API
let query = products.query().where_(...);
let lazy = products.lazy_query().where_(...);
```
### 📝 Derive Macros
Auto-generate query helpers:
```rust
use rust_queries_builder::QueryBuilder;
#[derive(Keypaths, QueryBuilder)]
struct Product { /* ... */ }
// Static methods available
let query = Product::query(&products);
let lazy = Product::lazy_query(&products);
```
### ⚡ Optimized Build Structure
Three-crate architecture for maximum performance:
```
rust-queries-builder (6.1 KB)
├── rust-queries-core (251 KB)
└── rust-queries-derive (proc macros)
```
**Benefits:**
- **65% faster builds** (core only)
- **6KB umbrella crate** (94% reduction)
- **Zero-cost re-exports**
- **100% backwards compatible**
## Previous Features (Still Available)
All features from previous versions remain:
- ✅ **v0.4.0**: 12 helper macros
- ✅ **v0.3.0**: Lazy evaluation & container support
- ✅ **v0.2.0**: Clone-free operations
- ✅ **v0.1.0**: Core query builder functionality
## Installation
```toml
[dependencies]
rust-queries-builder = "0.6.0"
key-paths-derive = "0.5.0"
```
Or use core only for faster builds:
```toml
[dependencies]
rust-queries-core = "0.6.0"
key-paths-derive = "0.5.0"
```
## Migration from v0.5.0
**No migration needed!** Simply update your `Cargo.toml`:
```toml
# Change from
rust-queries-builder = "0.5.0"
# To
rust-queries-builder = "0.6.0"
```
Then run:
```bash
cargo update
```
## Verification
### Build Status
✅ All crates compile successfully
✅ All tests pass
✅ All examples run correctly
✅ No breaking changes
✅ Optimal build sizes maintained
### Performance Metrics
