# Migration from 0.4 to 0.5
* `HttpResponseBuilder::body()`, `.finish()`, `.json()`
methods return `HttpResponse` instead of `Result<HttpResponse>`
* `actix_web::Method`, `actix_web::StatusCode`, `actix_web::Version`
moved to `actix_web::http` module
* `actix_web::header` moved to `actix_web::http::header`
* `NormalizePath` moved to `actix_web::http` module
* `HttpServer` moved to `actix_web::server`, added new `actix_web::server::new()` function,
shortcut for `actix_web::server::HttpServer::new()`
* `DefaultHeaders` middleware does not use separate builder, all builder methods moved to type itself
* `StaticFiles::new()`'s show_index parameter removed, use `show_files_listing()` method instead.
* `CookieSessionBackendBuilder` removed, all methods moved to `CookieSessionBackend` type
* `actix_web::httpcodes` module is deprecated, `HttpResponse::Ok()`, `HttpResponse::Found()` and other `HttpResponse::XXX()`
functions should be used instead
* `ClientRequestBuilder::body()` returns `Result<_, actix_web::Error>`
instead of `Result<_, http::Error>`
* `Application` renamed to a `App`
* `actix_web::Reply`, `actix_web::Resource` moved to `actix_web::dev`
