This version instead of showing the full link shows a short description, and it replaces a public web address with an internal URI scheme that the app uses (simplex:/) – such links open directly in the app. There is an option to show the full link, if you need it, and even to open it in the browser from the app, but in this case if this link is not using https://simplex.chat website it will show as red to highlight it.
