+## Release 6.0.1
+
+- Fix imports [[0106351]](http://github.com/elasticsearch/elasticsearch-php/commit/0106351)
+- ClientBuilder: setLogger() and setTracer() only accept \Psr\Log\LoggerInterface (#673) [[0270c4f]](http://github.com/elasticsearch/elasticsearch-php/commit/0270c4f)
+- fix for invalid GET /_aliases route. (#663) [[6d467fa]](http://github.com/elasticsearch/elasticsearch-php/commit/6d467fa)
+- Remove PutTemplate endpoint, lang param of PutScript no longer used [[a13544f]](http://github.com/elasticsearch/elasticsearch-php/commit/a13544f)
+  Note: I'm considering PutTemplate removal a bugfix, since the API doesn't exist in ES Core anymore. Using the endpoint throws an error,
+  so the removal is just fixing an existing bug, hence `6.0.1` instead of `6.1.0`
+
