## 8.16.0 (2026-02-19)
### New features
The `sourceType` option can now be set to `"commonjs"` to have the parser treat the top level scope as a function scope.
Add support for Unicode 17.
### Bug fixes
Don't recognize `await using` as contextual keywords when followed directly by a backslash.
Fix an issue where the parser would allow `return` statements in `static` blocks when `allowReturnOutsideFunction` was enabled.
Properly reject `using` declarations that appear directly in `switch` or `for` head scopes.
Fix some corner case issues in the recognition of `using` syntax.

## Importing acorn
ESM as well as CommonJS is supported for all 3: `acorn`, `acorn-walk` and `acorn-loose`.
ESM example for `acorn`:
```js
import * as acorn from "acorn"
```
CommonJS example for `acorn`:
```js
let acorn = require("acorn")
```
ESM is preferred, as it allows better editor auto-completions by offering TypeScript support.
For this reason, following examples will use ESM imports.
