## New Features

### External OpenSearch Support

Chef Infra Server now supports external OpenSearch for indexing.

## Improvements

- Improved performance of `chef-server-ctl reindex-opc-piecewise`.

- Fixed an inconsistency issue with `knife search`. The inconsistency was due to the `read_only_allow_delete` setting in Elasticsearch, which would not update indices. Added preflights to identify Elasticsearch's `read_only_allow_delete` setting in an index.

- Replaced the opscode wordmark with a configurable name in folder names, hardcodes of chef-server.rb, chef-server-running.json, and chef-secrets.json.
