+For the v1 series, the `DocumentList` type's members `hasItems` and `items` are functions; in the v2 series, they are properties. Additionally, the `Option` and `Result` types included in the project have a similar difference; see the [v1 README](https://git.bitbadger.solutions/bit-badger/inspired-by-fsharp/src/branch/v1/README.md) for PHP 8.2 or 8.3 and the [v2 README](https://git.bitbadger.solutions/bit-badger/inspired-by-fsharp/src/branch/main/README.md) for PHP 8.4. Both versions are supported; the v1 / v2 distinction helps composer make the right choice based on the target PHP version of your project.
