Since I updated to NC18.0.1, WhatsNewController.php is getting an error.

```
[PHP] Error: Undefined index: changelogURL at /MY-NEXTCLOUD/core/Controller/WhatsNewController.php#91

GET /ocs/v2.php/core/whatsnew?format=json
from USER-INFO

```

Is there a workaround for this?

Is this the issue that is causing the “Connection to server lost” message that comes every time I login on NC18?

In my case, it is different. Users are unaware of the error.
