## 6.0.0 - 2018-02-07

Major version release. List of backwards incompatible changes to watch out for:

-   The minimum PHP version is now 5.4.0. If you're using PHP 5.3 or older, consider upgrading to a more recent version.

*   `\Stripe\AttachedObject` no longer exists. Attributes that used to be instances of `\Stripe\AttachedObject` (such as `metadata`) are now instances of `\Stripe\StripeObject`.

-   Attributes that used to be PHP arrays (such as `legal_entity->additional_owners` on `\Stripe\Account` instances) are now instances of `\Stripe\StripeObject`, except when they are empty. `\Stripe\StripeObject` has array semantics so this should not be an issue unless you are actively checking types.

*   `\Stripe\Collection` now derives from `\Stripe\StripeObject` rather than from `\Stripe\ApiResource`.
