The highlight of this release is support for Micrometer metrics that comes with experimental status.

To enable Micrometer metrics, you need to:

• 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 that is discovered automatically.
