We have another release-candidate on our roadmap before 1.0.0 which will contain a simple implementation for webspaces and the missing feature shadow articles. Additionally we will fix the conflict for the ongr-io/ElasticsearchBundle 5.0.6 which introduces a BC break and is currently not compatible with the SuluArticleBundle.
After this last release-candidate we will release 1.0.0 if there is no big issue anymore.
Also in the near future, we will publish the 2.0.0 release. Which wont bring any new important feature will introduce the compatibility to sulu's new Admin-UI and the compatibility to Elasticsearch 6.0.
You see we are planning lots of things in the near future of this bundle.
We are happy to hear feedback. If you have problems feel free to create an issue or contact us via Slack.
