# optics-extra-0.4.2 (2022-05-19)
* Allow `transformers-0.6` and `mtl-2.3`
Note that `optics-extra` no longer defines `Zoom` instances for `ErrorT` or `ListT` when
building with `mtl-2.3` or later. This is because `MonadState` is a superclass of
`Zoom`, and the `MonadState` instances for `ErrorT` and `ListT` were removed in
`mtl-2.3`. Be watchful of this if you build `optics-extra` with `mtl-2.3` (or
later) combined with an older version of `transformers` (pre-0.6) that defines
`ErrorT` or `ListT`. Similarly for `Magnify` and `MagnifyMany`.
