 ## [Unreleased]
 
 ### Added
+- New methods in JavaScript implementation to match Java ([#62](https://github.com/cucumber/query/pull/62))
 - Update dependency @cucumber/messages to v26  ((#52)[https://github.com/cucumber/query/pull/52])
 - Update dependency io.cucumber:messages up to v26 ((#53)[https://github.com/cucumber/query/pull/53])
 
+### Changed
+- BREAKING CHANGE: `countMostSevereTestStepResultStatus` now returns `EnumMap` with all statuses regardless of count ([#62](https://github.com/cucumber/query/pull/62))
+- BREAKING CHANGE: `findAllTestCaseStarted` now omits `TestCaseStarted` messages where there is or will be another attempt ([#62](https://github.com/cucumber/query/pull/62))
+- BREAKING CHANGE: Rename `findMostSevereTestStepResulBy` to `findMostSevereTestStepResultBy` ([#62](https://github.com/cucumber/query/pull/62))
+
+### Removed
+- BREAKING CHANGE: Remove support for Node.js 16.x and 17.x ([#62](https://github.com/cucumber/query/pull/62))
+
 ## [12.2.0] - 2024-06-22

+
+## Adding or changing query methods
+
+This is a polyglot repo with several languages adhering to a common suite of acceptance tests. A change should be made consistently across all languages. Currently, the list is:
+
+- Java (reference)
+- JavaScript
+
+Java is the reference implementation in the sense that it is responsible for generating the fixtures that are used in the acceptance tests to verify all implementations.
+
+So your playbook for adding a method would be something like:
+
+1. Add the method in `Query.Java` with test(s) in `QueryTest.java`
+2. Extend `QueryAcceptanceTest.java` to include verifications for the new method
+3. Run `QueryAcceptanceTest::updateExpectedQueryResultFiles` to regenerate the fixtures
+4. Implement other languages
+
+## Types
+
+Choosing which type to use in another language based on what we did in Java is an inexact science. This table defines all the decisions we've made so far:
+
+| Java                | JavaScript              |
+|---------------------|-------------------------|
+| `Optional<T>`       | `T \| undefined`[^1]    |
+| `List<T>`           | `ReadonlyArray<T>`      | 
+| `Map<K, V>`         | `Map<K, V>`             | 
+| `EnumMap<K, V>`     | `Record<K, V>`          | 
+| `List<Entry<T, V>>` | `ReadonlyArray<[T, V]>` |
