`reqHeader` not in scope

[awasthishubh]

So I started with Haskell recently and now I am learning Scotty to make simple web server. I got this error which says reqHeader not in scope. I saw this code at different tutorials. Is something changed? Do I need to add any extra import? Code

{-# LANGUAGE OverloadedStrings #-}
import Web.Scotty
import qualified Data.Text as T
import Control.Monad.IO.Class
import Network.HTTP.Types

main = scotty 3000 $ do
    get "/" $ do
        liftIO $ putStrLn $ "XXXXXXXXXXXXXXXXXXXXXX"
        agent <- reqHeader "User-Agent"
        text agent

Error log:

According to the change log, reqHeader was renamed to header and deprecated in version 0.7.0, and removed in 0.8.0.
