ArangoDB 3.4 GA Release: Full-Text Search, GeoJSON, Streaming and More

I am wondering if the new S2 geo indexes are downwards-compatible and can be used with existing data from previous release. Do you see any obstacles for upgrading to 3.4 coming from an older release?

Do you have any benchmark results for ArangoSearch compared to similar products such as Elasticsearch?

Is ArangoSearch an Enterprise feature or is it available in the free Community Edition?

How do you solve the problem of persistent data in Kubernetes?
