 ## v0.18.0
 
+### Breaking changes
+
+- Graphile Worker is now published as an ESM package (`"type": "module"`). Use
+  `import` syntax from ESM consumers. Since Graphile Worker requires Node
+  22.18+, CommonJS consumers can continue to load Worker with `require()` via
+  Node's `require(esm)` support.
+- Example `.js` task and configuration files now use ESM syntax. In projects
+  with `"type": "module"`, `.js` task files must use `export default`; rename
+  CommonJS tasks/configuration to `.cjs` if you need to keep using
+  `module.exports`.
+- TypeScript task files with `.ts` and `.mts` extensions are now recognized by
+  default and loaded through Node's native type stripping. Only erasable,
+  verbatim TypeScript syntax is supported without a custom loader or
+  precompilation.
+
+### Changes
+
 - Since Node 20 is EOL, Node 22 is now the minimum supported version, per our
   [requirements documentation](https://worker.graphile.org/docs/requirements).
 - `Runner` gains `[Symbol.asyncDispose]()` method, so you can

+Graphile Worker includes `.ts` and `.mts` in its default task file extensions.
+On the supported Node.js versions, these files are loaded by Node's native type

-
-:::
-
-To load TypeScript files directly as task executors (without precompilation),
-one way is to do the following:
-
-1. Install `ts-node`.
-2. Add `".ts"` to the `worker.fileExtensions` list in your preset.
-3. Run Graphile Worker with the environment variable
-   `NODE_OPTIONS="--loader ts-node/esm"` set.
