	Weblinks was decoupled back in Joomla 3.4. If it was in use on a 2.5 site, the migration process would note this and migrate the Weblinks component and data. For the migration from 3.10.x to 4.x, it will be the same. It is still available and maintained on the JED at [https://extensions.joomla.org/category/official-extensions/ Official Extensions].

			==== Notes on Legacy Routing ====
			Legacy routing will not be available in Joomla 4.x. Only Modern will be available. When you do the migration, if you are using Legacy routing, the system will automatically change them to Modern routing. You will want to run a broken link checker on your site after migrating to Joomla 4.x and ''before you go live''.
