### 4.4.4

The highlight of this release is support for [Micrometer](https://micrometer.io/) metrics that comes with experimental status.

To enable Micrometer metrics, you need to:
- include Micrometer dependencies on classpath
- enable Micrometer metrics via driver configuration

Sample driver configuration:
```
var config = Config.builder()
		.withMetricsAdapter(MetricsAdapter.MICROMETER)
		.build();

var driver = GraphDatabase.driver(url, AuthTokens.basic(username, password), config);
```

At this stage we only support the [global registry](https://micrometer.io/docs/concepts#_global_registry) that is discovered automatically.

In addition, this release brings several general improvements and dependency updates.
