🆕 What's New in v2.0
--------------------

[](#-whats-new-in-v20)

The CodeIgniter SDK has been **hardened** with enterprise-grade features:

### State-Based Validation

[](#state-based-validation)

Instead of raw API responses, use typed `LicenseState` objects:

```
helper('getkeymanager');

$state = resolve_license_state($key);

if ($state->isActive()) {
    // License is fully active
} elseif ($state->isInGracePeriod()) {
    // Grace period - network issues
} else {
    // Invalid
}
```

### Grace Period Protection

[](#grace-period-protection)

Automatic 72-hour grace period when API is unreachable:

- Prevents service disruption from network issues
- Cached licenses remain valid temporarily
- Configurable duration

### Enhanced Error Handling

[](#enhanced-error-handling)

```
use GetKeyManager\CodeIgniter\Core\ApiResponseCode;
use GetKeyManager\CodeIgniter\Core\LicenseException;

try {
    $state = resolve_license_state($key);
} catch (LicenseException $e) {
    $code = $e->getApiCode();
    $name = $e->getApiCodeName();
    $message = ApiResponseCode::getMessage($code);
}
```

### New State-Based Helpers

[](#new-state-based-helpers)

```
// Check license status
is_license_active($key);
is_license_in_grace_period($key);

// Feature checking
can_use_feature($key, 'premium_reports');

// State management
$state = get_license_state($key);  // Get cached state
clear_license_state($key);          // Clear cache
```

**👉 See [HARDENING\_COMPLETE.md](HARDENING_COMPLETE.md) for full documentation**

**✅ 100% Backward Compatible** - All existing code continues to work!
