## [0.2.0] - 2025-01-21
6+
7+
### Added
8+
9+
#### 🔐 Advanced Security Features
10+
- **Memory-Safe Secret Management**: New `secure` feature with `secrecy` crate integration
11+
- `load_secrets_secure()` - Load secrets as `SecretString` types
12+
- `load_secret_key_secure()` - Load individual secrets with memory safety
13+
- `env_secret()` - Load environment variables as secure secrets
14+
- Automatic memory zeroization when secrets are dropped
15+
- Debug output protection (secrets automatically redacted)
16+
17+
#### 🎯 Type-Safe Secret Injection
18+
- **SecretInjectable Trait**: Compile-time safe secret injection into configuration types
19+
- `inject_secret()` method for custom secret handling
20+
- `validate_secrets()` method for post-injection validation
21+
- `load_config_with_secrets()` for automatic injection with validation
22+
23+
#### 🛡️ Security Validation & Template Processing
24+
- **Secret Strength Validation**: `validate_secret()` method
25+
- Minimum length requirements (8+ characters)
26+
- Common weak pattern detection
27+
- Character complexity analysis
28+
- **Template-Based Secret Injection**: `load_config_with_secret_injection()`
29+
- `${VARIABLE}` placeholder substitution in configuration files
30+
- Comprehensive error handling for missing secrets
31+
- Validation ensures no unresolved placeholders
32+
33+
#### 📋 Enhanced Configuration Management
34+
- **Multi-Format Support**: Enhanced support for .toml, .json, .yaml files
35+
- **Export Statement Parsing**: Support for both `KEY=VALUE` and `export KEY=VALUE` formats
36+
- **Layered Configuration**: `load_config_layered()` for configuration composition
37+
- **Schema Validation**: `load_config_with_validation()` with JSON Schema support
38+
39+
#### 🧪 Comprehensive Testing Infrastructure
40+
- **231 Test Cases**: Complete test coverage across all features
41+
- Integration tests for core functionality
42+
- Security tests for memory safety validation
43+
- Performance tests (handles 1000+ secrets in <100ms)
44+
- Edge case testing for robust error handling
45+
- **TDD Implementation**: All features developed following Test-Driven Development
46+
- **Cross-platform Compatibility**: Tests validated on multiple platforms
47+
48+
#### 🔧 Developer Experience Improvements
49+
- **Zero-Cost Abstractions**: No performance impact when secure features disabled
50+
- **Comprehensive Error Types**: Specific error variants for all failure modes
51+
- `SecretValidationError` for validation failures
52+
- `SecretInjectionError` for injection problems
53+
- **Feature Flag Architecture**: Granular control over enabled functionality
54+
- `serde` (default) - Configuration loading
55+
- `glob` - Resource discovery
56+
- `secrets` - Basic secret management
57+
- `secure` - Memory-safe secret handling
58+
- `validation` - Schema-based validation
59+
- `testing` - Test utilities
60+
61+
### Enhanced
62+
63+
#### 📖 Documentation & Examples
64+
- **Complete API Reference**: Comprehensive method documentation with examples
65+
- **Security Best Practices**: Detailed security guidance and migration paths
66+
- **Real-world Examples**: Production-ready code samples for all features
67+
- **Type-safe Examples**: SecretInjectable trait implementation examples
68+
69+
#### ⚡ Performance & Reliability
70+
- **Optimized Secret Loading**: Efficient parsing of large secret files
71+
- **Memory Efficiency**: Minimal memory footprint with smart resource management
72+
- **Error Recovery**: Graceful handling of malformed files and missing resources
73+
- **Concurrent Safety**: Thread-safe operations across all public APIs
74+
75+
### Technical Details
76+
77+
- **Dependencies**: Added optional `secrecy` and `zeroize` crates for memory safety
78+
- **Feature Gates**: All new functionality properly gated behind feature flags
79+
- **Code Style**: Maintains project's 2-space indentation and style requirements
80+
- **Clippy Clean**: Zero warnings with `-D warnings` flag
81+
- **Documentation Tests**: All examples compile and run successfully
82+
83+

94+
## Migration Guide
95+
96+
### From Basic to Secure Secret Management
97+
98+
**Before (v0.1.x):**
99+
```rust
100+
let api_key = workspace()?.load_secret_key("API_KEY", "-secrets.sh")?;
101+
println!("API Key: {}", api_key); // Secret exposed in logs!
102+
```
103+
104+
**After (v0.2.0):**
105+
```rust
106+
use secrecy::ExposeSecret;
107+
let api_key = workspace()?.load_secret_key_secure("API_KEY", "-secrets.sh")?;
108+
println!("API Key: {}", api_key.expose_secret()); // Explicit access required
109+
```
110+
111+
### Enabling Advanced Features
112+
113+
Add features to your `Cargo.toml`:
114+
```toml
115+
[dependencies]
116+
workspace_tools = { version = "0.2", features = ["secure", "validation"] }
117+
```
118+
119+
For complete migration examples and best practices, see the [API Reference](#-api-reference) section.
