All notable changes to [bpmn-js](https://github.com/bpmn-io/bpmn-js) are documented here. We use [semantic versioning](http://semver.org/) for releases.
* Reworked the link of elements to bpmn DIs. You must access the `di` directly from the diagram element instead of the `businessObject`. [#1472](https://github.com/bpmn-io/bpmn-js/issues/1472)
*`FIX`: serialize `bpmn:DataStoreReference` correctly in case if first participant is an empty pool ([#1456](https://github.com/bpmn-io/bpmn-js/issues/1456))
*`FEAT`: improve replace label for collapsed pools ([`8faee2bd`](https://github.com/bpmn-io/bpmn-js/commit/8faee2bde9a74b75b4b6bb9b003507652e75c9c5))
*`FEAT`: allow participant multiplicity marker to be toggled ([#533](https://github.com/bpmn-io/bpmn-js/issues/533))
