Changelog of @hackage/base-compat-batteries 0.13.1

Changes in 0.13.1 [2023.10.11]

Changes in 0.13.0 [2023.03.10]

  • This coincides with the base-compat-0.13.0 release. Refer to the base-compat changelog for more details.
  • Require OneTuple-0.4 or later on GHC 7.4+, as that is the first OneTuple release to backport the MkSolo data constuctor for Solo. See Data.Tuple.Compat.
  • Introduce Data.Foldable1.Compat and Data.Bifoldable1.Compat modules, which correspond to changes made in base-4.18.0.0. base-compat-batteries uses the foldable1-classes-compat library to backport this code to older versions of base.
  • Depend on bifunctor-classes-compat to backport the Bifunctor, Bifoldable, and Bitraversable classes instead of the bifunctors library, which has more dependencies.

Changes in 0.12.3 [2023.07.12]

  • Allow building with OneTuple-0.4.*.

Changes in 0.12.2 [2022.08.11]

  • This coincides with the base-compat-0.12.2 release. Refer to the base-compat changelog for more details.

Changes in 0.12.1 [2021.10.30]

  • Backport Solo to the Data.Tuple.Compat module. If using ghc-prim-0.7.0 or later, Solo is taken from ghc-prim. If using an older version of ghc-prim, Solo is taken from the OneTuple compatibility library.

  • This coincides with the base-compat-0.12.1 release. Refer to the base-compat changelog for more details.

Changes in 0.12.0 [2021.08.29]

  • Data.Semigroup.Compat{.Repl.Batteries} no longer re-exports the Option data type or the option function, as both have been removed in base-4.16.

  • This coincides with the base-compat-0.12.0 release. Refer to the base-compat changelog for more details.

Changes in 0.11.2 [2020.09.30]

  • This coincides with the base-compat-0.11.2 release. Refer to the base-compat changelog for more details.

Changes in 0.11.1 [2020.01.27]

  • This coincides with the base-compat-0.11.1 release. Refer to the base-compat changelog for more details.

Changes in 0.11.0 [2019.09.06]

  • Reexport MonadFail(fail) from Prelude.Compat and Control.Monad.Compat.

    Because Prelude.Compat.fail now corresponds to the fail from MonadFail instead of Monad, some care is required to implement Monad.fail on pre-8.8 versions of GHC. The following template is recommended:

    import Prelude.Compat
import qualified Control.Monad      as Monad
import qualified Control.Monad.Fail as Fail

data Blah a = ...

instance Functor Blah where ...
instance Applicative Blah where ...

instance Monad.Monad Blah where
  (>>=) = ...
#if !(MIN_VERSION_base(4,13,0))
  fail = Fail.fail
#endif

instance Fail.MonadFail Blah where
  fail = ...

    This approach is also backwards-compatible with previous releases of base-compat-batteries.

  • Introduce the Data.Type.Equality.Compat module, which reexports Data.Type.Equality from base (if using a sufficiently recent version of GHC) or the type-equality library (if using an old GHC).

  • This coincides with the base-compat-0.11.0 release. Refer to the base-compat changelog for more details.

Changes in 0.10.5 [2018.10.18]

  • This coincides with the base-compat-0.10.5 release. Refer to the base-compat changelog for more details.

Changes in 0.10.4 [2018.07.03]

  • Add a SafeHaskellSpec test which ensures that certain modules (such as Prelude.Compat) can be imported in the presence of Safe.
  • This coincides with the base-compat-0.10.4 release. Refer to the base-compat changelog for more details.

Changes in 0.10.3 [2018.07.02]

  • This coincides with the base-compat-0.10.3 release. Refer to the base-compat changelog for more details.

Changes in 0.10.2 [2018.07.02]

  • Sync with base-4.12/GHC 8.6
  • Introduce the Data.Functor.Contravariant.Compat module, which reexports Data.Functor.Contravariant from base (if using GHC 8.6 or later) or the contravariant library (if using an earlier version of GHC).
  • This coincides with the base-compat-0.10.2 release. Refer to the base-compat changelog for more details.

Changes in 0.10.1 [2018.04.10]

  • Add Data.List.NonEmpty.Compat.
  • Reexport (Data.Semigroup.<>) from Data.Monoid.Compat.
  • Tighten lower bounds of compat package dependencies.
  • This coincides with the base-compat-0.10.1 release. Refer to the base-compat changelog for more details.

Changes in 0.10.0 [2018.04.05]

  • Sync with base-4.11/GHC 8.4
  • This coincides with the base-compat-0.10 release. Refer to the base-compat changelog for more details.
