 * [#320](https://github.com/codegram/hyperclient/pull/320): Documented how to handle non-`hal+json` responses via the Faraday response middleware's `content_type` matcher - [@dblock](https://github.com/dblock).
 * [#321](https://github.com/codegram/hyperclient/pull/321): Added Ruby 4.0 to the CI test matrix - [@dblock](https://github.com/dblock).
 * [#322](https://github.com/codegram/hyperclient/pull/322): Fixed `Link` caching a mutating request's (`_post`/`_put`/`_patch`/`_delete`) response as its resource, causing subsequent reads (e.g. `#each`, `method_missing`) to return stale data instead of a fresh `_get` - [@dblock](https://github.com/dblock).
+* [#325](https://github.com/codegram/hyperclient/pull/325): Added JSON 2.x/3.x to the CI matrix and JSON response parsing regression tests, retaining Ruby 2.7 coverage with JSON 2.x; upgraded RuboCop to 1.91.0 to allow JSON 3.x - [@dblock](https://github.com/dblock).

+CI runs the test suites with JSON 2.x on Ruby 2.7, both JSON 2.x and 3.x on Ruby 3.2, and JSON 3.x on Ruby 3.4, Ruby 4.0, and the head builds.
+To select a JSON major version locally, resolve the bundle and run the tests with the same `JSON_VERSION`:
+
+```
+JSON_VERSION=2 bundle update json
+JSON_VERSION=2 bundle exec rake test spinach
+JSON_VERSION=3 bundle update json

 The examples in this README use the [Splines Demo API](https://github.com/ruby-grape/grape-with-roar) running [here](https://grape-with-roar.herokuapp.com/api). Use version 1.x with Faraday 1.x, and version 2.x with Faraday 2.x. If you're upgrading from a previous version, please make sure to read [UPGRADING](UPGRADING.md).
 
+Hyperclient is tested with JSON 2.x on Ruby 2.7, both JSON 2.x and 3.x on Ruby 3.2, and JSON 3.x on newer Rubies. JSON 3.x requires a Faraday release with keyword parser options support (2.14.4+).
