# v3.7.0

Released on 2019-07-28.

Convenience features and house-keeping. All changes are backward-compatible.

- Adds a [`contains`](../../api/basic_json/contains.md) overload that checks a JSON pointer without
  throwing, a generic `to_string`, and a return value for
  [`emplace_back`](../../api/basic_json/emplace_back.md).
