{{#module name="koa-router"}}{{>body}}{{/module}}## Migrating to 7 / Koa 2

- The API has changed to match the new promise-based middleware
  signature of koa 2. See the
  [koa 2.x readme](https://github.com/koajs/koa/tree/2.0.0-alpha.3) for more
  information.
- Middleware is now always run in the order declared by `.use()` (or `.get()`,
  etc.), which matches Express 4 API.
