This disallows putting URLs in topic titles for TL0 users, which means that:
- If a TL-0 user puts a link into the title, a topic featured link won’t be generated (as if it was disabled in the site settings)
- Server methods for creating and updating topics will be refusing featured links when they are called by TL-0 users
- TL-0 users won’t be able to put any link into the topic title. For example, the title “Hey, take a look at https://my-site.com” will be rejected:
Also, it improves a bit server behavior when creating or updating feature links on topics in the categories with disabled featured links. Before the server just silently ignored a featured link field that was passed to him, now it will be returning 422 response.
