Migrating from 4.x to 5.x
Not found state is now passed to middleware functions on start: if you use
allowNotFoundoption and have custom middleware functions, make sure they still work.
strictQueryParamsoption is now
falseby default: if you currently don't specify that option, you need to explicitely set it to
trueto keep the same behaviour.
