## Differences between GHC 8.10.7 and GHC 9.6.3
## Differences between GHC 8.10.7 and GHC 9.6.4
1. The main difference is related to `DuplicateRecordFields` extension.
It is no longer possible in GHC 9.6.3 to specify type when using selectors, instead OverloadedRecordDot extension and syntax are used that need to be removed in GHC 8.10.7:
It is no longer possible in GHC 9.6.4 to specify type when using selectors, instead OverloadedRecordDot extension and syntax are used that need to be removed in GHC 8.10.7:
```haskell
{-# LANGUAGE DuplicateRecordFields #-}
-- use this in GHC 9.6.3 when needed
-- use this in GHC 9.6.4 when needed
{-# LANGUAGE OverloadedRecordDot #-}
-- GHC 9.6.3 syntax
-- GHC 9.6.4 syntax
let x = record.field
-- GHC 8.10.7 syntax removed in GHC 9.6.3
-- GHC 8.10.7 syntax absent in GHC 9.6.4
let x = field (record :: Record)
```
It is still possible to specify type when using record update syntax, use this pragma to suppress compiler warning:
```haskell
-- use this in GHC 9.6.3 when needed
-- use this in GHC 9.6.4 when needed

2. Most monad functions now have to be imported from `Control.Monad`, and not from specific monad modules (e.g. `Control.Monad.Except`).
```haskell
-- use this in GHC 9.6.3 when needed
-- use this in GHC 9.6.4 when needed
import Control.Monad
