+## [1.3.0] – 2025-12-09
+
+### Added
+
+-   **Global database helpers** integrating the `codemonster-ru/database` package:
+    -   `db()` — returns the active database connection
+    -   `schema()` — returns schema builder for the selected connection
+    -   `transaction()` — executes callbacks inside a DB transaction
+-   Full PHPUnit test coverage for:
+    -   `db()` helper
+    -   `schema()` helper
+    -   With isolated `DatabaseManager` and fake container bindings
+-   Support for SQLite, MySQL and future drivers automatically via `ConnectionInterface::schema()`.
+
+### Changed
+
+-   `SupportFakeContainer` updated for correct behavior with database helpers:
+    -   `singleton()` is now **eager**, ensuring immediate instance creation
+    -   Improved compatibility with Annabel-style lazy container contracts
+    -   Fully stable integration with request/view/db helpers
+-   Strengthened test isolation:
+    -   `reset()` now clears both bindings and instances
+    -   All tests run without requiring the Annabel framework
+
+### Fixed
+
+-   `schema()` test failing due to instantiation of an abstract Grammar class  
+    → Now resolved automatically by the database package selecting proper driver grammar.
+-   DB helper now correctly bootstraps connection configuration even without other framework components.
+

+> These helpers are framework‑agnostic and automatically enabled when installed.
 
 ## 🚀 Usage
 
-All helpers are automatically registered via Composer’s autoloading.
-You can call them from anywhere in your application.
-
 ```php
 <?php
 
 require __DIR__ . '/vendor/autoload.php';
 
-// Environment variables
-$value = env('APP_ENV', 'production');
+// ENV
+$env = env('APP_ENV', 'production');
 
-// Configuration
+// Config
 config(['app.name' => 'Codemonster']);
+echo config('app.name');
 
-echo config('app.name'); // Codemonster
-
-// HTTP request and response
+// Requests & Responses
 $request = request();
-$response = response('Hello World', 200);
-$response->send();
+return response('Hello World', 200);
 
 // Router
 router()->get('/', fn() => response('Home'));
-router()->post('/contact', fn() => response('Contact form submitted'));
 
-// View rendering
+// Views
 echo render('emails.welcome', ['user' => 'Vasya']);
 
-// Debugging
+// Debug
 dump($request);
-dd('Goodbye');
+dd('Bye!');
 ```
 
-## 🧪 Testing
+## 🗄 Database Helpers (optional)
+
+If `codemonster-ru/database` is installed:
+
+```php
+$conn = db();         // default connection
+$conn = db('mysql');  // named connection
+
+schema()->create('users', function ($table) {
+    $table->id();
+    $table->string('name');
+});
 
-You can run tests with the command:
+transaction(function ($db) {
+    $db->table('logs')->insert(['msg' => 'ok']);
+});
+```
+
+## 🧪 Testing
 
 ```bash
 composer test
