In Racket 5.0.2 and before, the Web Server supported implicit
conversion of X-expressions and lists with the format (cons/c bytes? (listof (or/c string? bytes?))) into response data structures for output.
After 5.0.99.4, this implicit conversion has been generalized into any->response. In the process, implicit conversion has been completely removed from some internal plumbing AND the response structures have been streamlined---primarily for efficiency.

This document describes the incompatible changes and how to restore the old behavior when that is possible.

@section{Why is my servlet failing with a @racket[can-be-response?] contract violation after updating Racket?}
After 5.0.99.4, the Web Server had a backwards incompatible change that prevents X-expressions and lists of bytes from being directly returned from servlets. Please read @filepath{PLTHOME/collects/web-server/compat/0/README} to learn about porting your servlets forward. Don't worry. It's easy.
