 ### Changes
 * Bump the dev version of Gradle from `7.5.1` to `7.6` ([#1409](https://github.com/diffplug/spotless/pull/1409))
   * We also removed the no-longer-required dependency `org.codehaus.groovy:groovy-xml`
+* Breaking changes to Spotless' internal testing infrastructure `testlib` ([#1443](https://github.com/diffplug/spotless/pull/1443))
+  * `ResourceHarness` no longer has any duplicated functionality which was also present in `StepHarness`
+  * `StepHarness` now operates on `Formatter` rather than a `FormatterStep`
+  * `StepHarnessWithFile` now takes a `ResourceHarness` in its constructor to handle the file manipulation parts
+  * Standardized that we test exception *messages*, not types, which will ease the transition to linting later on

+    <gson />      <!-- has its own section below -->
+  </json>
+</configuration>
+```
+
+### simple
+
+Uses a JSON pretty-printer that optionally allows configuring the number of spaces that are used to pretty print objects:
+
+```xml
+<simple>
+  <indentSpaces>4</indentSpaces>    <!-- optional: specify the number of spaces to use -->
+</simple>
+```
+
+### Gson
+
+Uses Google Gson to also allow sorting by keys besides custom indentation - useful for i18n files.
+
+```xml
+<gson>
+  <indentSpaces>4</indentSpaces>        <!-- optional: specify the number of spaces to use -->
+  <sortByKeys>false</sortByKeys>        <!-- optional: sort JSON by its keys -->
+  <escapeHtml>false</indentSpaces>      <!-- optional: escape HTML in values -->
+  <version>2.8.1</version>              <!-- optional: specify version -->
+</gson>
+```
+
+Notes:
+* There's no option in Gson to leave HTML as-is (i.e. escaped HTML would remain escaped, raw would remain raw). Either
+all HTML characters are written escaped or none. Set `escapeHtml` if you prefer the former.
+* `sortByKeys` will apply lexicographic order on the keys of the input JSON. See the
+[javadoc of String](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/String.html#compareTo(java.lang.String))
+for details.
