Back-end changes

Removed from public namespace

  • \OCP\App::checkAppEnabled

  • \OCP\Security\StringUtils

  • \OCP\Util::callCheck


  • \OCP\AppFramework\Http\EmptyContentSecurityPolicy::allowEvalScript: This means apps should no longer use eval in their JavaScript. We aim to forbid this in general in a future version of Nextcloud.

  • \OCP\AppFramework\Utility\IControllerMethodReflector::reflec: Will be removed in 18.

Behavioral changes

  • LDAP: default value for ldapGroupMemberAssocAttr changed from uniqueMember to unset. On scripted setups, it has to be set if LDAP groups should be used within Nextcloud.

  • Provisioning API: creating users will return the assigned user ID as dataset, as in ['id' => $userid].
