Please update to [version 3.6.1](https://github.com/nlohmann/json/releases/tag/v3.6.1)!** This release adds some **convenience functions for JSON Pointers**, introduces a [`contains`]( http://nlohmann.github.io/json/classnlohmann_1_1basic__json_a0a45fc740637123fdf05fef970f8be47.html#a0a45fc740637123fdf05fef970f8be47) function to check if a key is present in an object, and improves the **performance of integer serialization**. Furthermore, a lot of small bug fixes and improvements have been made. All changes are backward-compatible. - Overworked the public interface for JSON Pointers. The creation of JSON Pointers is simplified with [`operator/`]( http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a90a11fe6c7f37b1746a3ff9cb24b0d53.html#a90a11fe6c7f37b1746a3ff9cb24b0d53) and [`operator/=`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a7395bd0af29ac23fd3f21543c935cdfa.html#a7395bd0af29ac23fd3f21543c935cdfa). JSON Pointers can be inspected with [`empty`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a649252bda4a2e75a0915b11a25d8bcc3.html#a649252bda4a2e75a0915b11a25d8bcc3), [`back`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a6bd5b554c10f15672135c216893eef31.html#a6bd5b554c10f15672135c216893eef31), and [`parent_pointer`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_afdaacce1edb7145e0434e014f0e8685a.html#afdaacce1edb7145e0434e014f0e8685a), and manipulated with [`push_back`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a697d12b5bd6205f8866691b166b7c7dc.html#a697d12b5bd6205f8866691b166b7c7dc) and [`pop_back`](http://nlohmann.github.io/json/classnlohmann_1_1json__pointer_a4b1ee4d511ca195bed896a3da47e264c.html#a4b1ee4d511ca195bed896a3da47e264c). #1434 - Added a boolean method [`contains`]( http://nlohmann.github.io/json/classnlohmann_1_1basic__json_a0a45fc740637123fdf05fef970f8be47.html#a0a45fc740637123fdf05fef970f8be47) to check whether an element exists in a JSON object with a given key.
