Hi everyone!
It's been a busy few months, but I've just pushed out a new release of the Elasticsearch Rust client I work on. I'm pretty excited to get this one out the door, I think it's setting us up quite nicely for future enhancements.
If you get a chance to check it out I'd love to hear your feedback 
Major changes
- All the libraries that make up the client are now collected in a single GitHub repository. This has the benefit of sharing CI infrastructure and being easier to contribute to
- Add an async API. Most of the code is shared through generics so the sync and async APIs appear similar
- Some proper integration test infrastructure that can test different client configurations against containerised clusters
In progress
- Support for connection pooling with static node addresses or sniffed addresses. The API is general enough that you could implement a connection pooling strategy with Zookeeper or marathon or whatever else
- Query DSL (exciting!)
- Reworking aggregations to be more generally useful
Upcoming
- Better support for bulk requests
- Reworking request parameters to avoid some unnecessary copies
- More integration tests and docs!
