+## 7.16.3

+### API

+Bugfix for [#1475](https://github.com/elastic/elasticsearch-ruby/issues/1475), an issue where if you indexed a document with an id such as `an id`, it would get escaped to `an+id` instead of `an%20id` when using `index` or `create`. This would result in the document id being `an+id` instead of the intended value `an id`.

+## 7.16.2

+No release.

 ## 7.16.1
