### Removed
* Public modules `middleware::{normalize, err_handlers}`. All necessary middleware structs are now
exposed directly by the `middleware` module.
* Remove `actix-threadpool` as dependency. `actix_threadpool::BlockingError` error type can be imported
from `actix_web::error` module. [#1878]

* Remove `ConnectError::SslHandshakeError` and re-export of `HandshakeError`.
due to the removal of this type from `tokio-openssl` crate. openssl handshake
error would return as `ConnectError::SslError`. [#1813]
* Remove `actix-threadpool` dependency. Use `actix_rt::task::spawn_blocking`.
Due to this change `actix_threadpool::BlockingError` type is moved into
`actix_http::error` module. [#1878]
