There seem to be some problems with this version, when using the manual install or when upgrading from a previous version. This post has more info.
After upgrading, DF stops working and this message is logged:
local.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Undefined class constant 'DreamFactory\Core\User\Resources\Custom::RESOURCE_NAME'' in /home/xxx/rest/vendor/dreamfactory/df-user/src/Services/User.php:127
So far, only people using the manual install or upgrade via git have reported this error.
