 - ``\OCP\Authentication\TwoFactorAuth\ILoginSetupProvider::getBody``, ``\OCP\Authentication\TwoFactorAuth\IPersonalProviderSettings::getBody`` and ``\OCP\Authentication\TwoFactorAuth\IProvider::getBody`` return type was broaden from ``\OCP\Template`` class to ``\OCP\Template\ITemplate`` interface. Should not change anything for applications.
+- ``\OCP\Files\Template\BeforeGetTemplatesEvent`` now takes an optional boolean constructor value, ``withFields``, that allows you to explicitly control whether template fields should be extracted. The default value is ``false``.
