unmaintained directory has been created to move packages which are no longer maintained. deku-router5 has been added to it: if you are interested in maintaining it, I'm happy to consider transferring ownership.teardown method (alongside onStart, onStop, onTransitionSuccess, etc.): it will be called when a plugin is removed.router5-plugin-browserrouter5-plugin-loggerrouter5-plugin-listenersrouter5-plugin-persistent-paramsuseMiddleware no longer returns your router instance, but a function to remove the added middleware. You can still pass multiple middleware, in which case calling the teardown function will remove all of them.usePlugin no longer returns your router instance, but a function to remove the added plugin. You can still pass multiple plugins, in which case calling the teardown function will remove all of them.hasPlugin method has been removed, and pluginName is no longer neededcloneRouter function, and it no longer re-uses existing dependenciesreload navigate option is set to true, fromState is no longer set to null: transitionPath has been updated to take into account this change, if you have middleware or plugins with custom logic, make sure you update them.useRoute, useRouteNode and useRouterLink has been renamed to ConnectedLink, and BaseLink has been renamed to LinkRouteProvider has been renamed to RouterProvider: there is now only one providerreact-router5 now requires React version 16.3.0 or above: it no longer uses the old context API. The migration path is quite easy:react-router5-hocs has been added: it is a drop-in replacement for react-router5 (Link component names stil need changed, see point above)react-router5 (see breaking changes above)router5Reducer from redux-router5-immutableredirect helper has been removed: it's no longer needed with forwardTo.
