Upgrading to version 2

TypeScript 4.1 is required:

npm install --save-dev typescript@>=4.1

If still using the function chaining syntax for routes, use the new syntax instead:

// OLD
route.get('/my/path')(middleware)(async request => { ... })

// NEW
route
  .get('/my/path')
  .use(middleware)
  .handler(async request => { ... })

Change route paths to use :param-style captures:

// OLD
route.get('/category/', URL.int('id'), '/tag/', URL.str('tag'))

// NEW
route.get('/category/:id(int)/tag/:tag')

If you had defined custom capturing functions, use route.useParamConversions() to use them in your paths.
