# Version 13.0.11 - 2026/08/13 {#version-13-0-11-2026-08-13}

This release marks the `Auth0Configuration` constructor parameter as explicitly nullable to
remove the implicit-nullable deprecation introduced with PHP 8.4 and prevents a spurious
"Missing code" error on every backend login form load.

## Download {#download}

Download this version from the [TYPO3 extension repository](https://extensions.typo3.org/extension/auth0/) or from
[GitHub](https://github.com/Leuchtfeuer/auth0-for-typo3/releases/tag/v13.0.11).

## Fixed {#fixed}

-   **Explicitly mark nullable constructor parameter:** The `$configPath` parameter of
    `Auth0Configuration::__construct()` now uses the explicit `?string` type instead of relying
    on an implicit null default. This silences the implicit-nullable parameter deprecation raised by
    PHP 8.4.
-   **Only exchange the Auth0 code when it is present:** The authorization code is only sent back
    when returning from Auth0. `Auth0Provider::getUserInfo()` no longer attempts the token exchange
    without it, which previously made the SDK throw "Missing code" on every plain login-form load.
-   **Aligned unit tests with the plural mapping API:** The unit tests for `Auth0Configuration` and
    `UserUtility` were adjusted to the plural mapping API and pass again.
