Status

Elastic is used in production with various versions of Elasticsearch. It is tested with the current and previous minor versions (1.3.9 and 1.4.4 at the time of this writing). Older versions should run fine, and Elasticsearch is quite stable with regards to its endpoints and JSON structure.

Elastic is not an official client, but it generally tries to be a good citizen. It uses many of the characteristics of the official clients (e.g. sniffing the cluster, keeping track of dead nodes, retrying requests automatically etc).

Regarding Go, I focus on the current version (1.4.2 at the time of this writing). On Travis, we automatically test with the previous version (1.3. now), the current version (1.4 now), and tip.
