The friendly URL (FURL) system is highly recommended currently and will be required in Invision Community 5.
All Cloud clients automatically have FURLs enabled automatically so there is no change for those communities.

We are removing support for plugins and instead you should use the applications system. Applications are more flexible than plugins and easier to manage.
Any existing plugins can easily be ported to applications and we encourage third-parties to start the process as soon as possible.
