Changelog of @hackage/base-compat 0.14.0

Changes in 0.14.0 [2024.04.30]

Sync with base-4.20/GHC 9.10
Backport foldl' to Prelude.Compat
Backport List to Data.List.Compat (when building with GHC 9.6 or later)
Backport append, appendList, prependList, permutations, permutations1, and sortOn to Data.List.NonEmpty.Compat (when building with GHC 8.0 or later)

Changes in 0.13.1 [2023.10.11]

Sync with base-4.19/GHC 9.8
Backport unzip to Data.Functor.Compat
Backport (!?) and unsnoc to Data.List.Compat
Backport getSolo to Data.Tuple.Compat when building against ghc-prim-0.8.0 (GHC 9.2) or later. To backport getSolo to older versions of GHC, import Data.Tuple.Compat from base-compat-batteries instead.
Backport decT and hdecT to Data.Typeable.Compat
Backport decTypeRep to Type.Reflection.Compat

Changes in 0.13.0 [2023.03.10]

Sync with base-4.18/GHC 9.6
Backport liftA2 being re-exported from Prelude.Compat.
Data.Tuple.Compat's Solo API now matches what is present in Data.Tuple in base-4.18. In particular, we now re-export both the MkSolo and Solo data constructors when building with ghc-prim-0.10.0 or later, with MkSolo being preferred over Solo. If you want to backport MkSolo to earlier versions of GHC, import Data.Tuple.Compat from base-compat-batteries instead.
Backport traceWith, traceShowWith, and traceEventWith to Debug.Trace. Note that traceEventWith is only provided when building with base-4.5 or later, as that is the first version of base to provide the traceEvent primitive on which traceEventWith is defined.
Backport inits1 and tails1 to Data.List.NonEmpty.Compat.
Backport minusNaturalMaybe to Numeric.Natural.Compat.
Backport applyWhen to Data.Function.Compat.
Backport mapAccumM and forAccumM to Data.Traversable.Compat.
Backport heqT to Data.Typeable.Compat. Note that heqT is only defined when building with base-4.10 or later, as that is the first version of base to provide the primitives needed to define heqT.
Introduce Data.Foldable1.Compat and Data.Bifoldable1.Compat modules, which correspond to changes made in base-4.18.0.0. You may consider using base-compat-batteries instead if you want increase the range of base versions that are supported.

Changes in 0.12.3 [2023.07.12]

This coincides with the base-compat-batteries-0.12.3 release. Refer to the base-compat-batteries changelog for more details.

Changes in 0.12.2 [2022.08.11]

Sync with base-4.17/GHC 9.4
Backport (.^.), (.>>.), (.<<.), (!>>.), (!<<.), oneBits to Data.Bits.Compat
Backport pattern TypeRep to Type.Reflection.Compat

Changes in 0.12.1 [2021.10.30]

Backport Solo to Data.Tuple.Compat when building with ghc-prim-0.7.0 or later

Changes in 0.12.0 [2021.08.29]

Sync with base-4.16/GHC 9.2
Data.Semigroup.Compat{.Repl} no longer re-exports the Option data type or the option function, as both have been removed in base-4.16.
Backport readBin and showBin to Numeric.Compat
Backport readBinP to Text.Read.Lex.Compat

Changes in 0.11.2 [2020.09.30]

Sync with base-4.15/GHC 9.0
Backport singleton to Data.List.Compat and Data.List.NonEmpty.Compat
Backport hGetContents', getContents', and readFile' added to System.IO.Compat

Changes in 0.11.1 [2020.01.27]

Sync with base-4.14/GHC 8.10
Backport isResourceVanishedError, resourceVanishedErrorType, and isResourceVanishedErrorType to System.IO.Error.Compat.

Changes in 0.11.0 [2019.09.06]

Sync with base-4.13/GHC 8.8
Backport MonadFail(fail) to 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.

Note that the MonadFail class has only been in base since base-4.9/GHC 8.0, so accordingly, this can only be backported back to GHC 8.0. If you wish to have a version of Prelude.Compat/Control.Monad.Compat that backports MonadFail to older GHCs (by conditionally depending on the fail library), use the Prelude.Compat/Control.Monad.Compat modules from the base-compat-batteries package.
Introduce the Data.Type.Equality.Compat module, which re-exports Data.Type.Equality if using base-4.7/GHC-7.8 or later. If using an older version of base, this module is empty.

If you wish to have a version of Data.Type.Equality.Compat with older GHCs (by conditionally depending on the type-equality library), use the Data.Type.Equality.Compat module from the base-compat-batteries package.

Changes in 0.10.5 [2018.10.18]

Enable BangPatterns in Prelude.Compat.

Changes in 0.10.4 [2018.07.03]

Make more modules Trustworthy. In particular, fix a regression in which Prelude.Compat was inferred as Unsafe by explicitly marking it as Trustwothy.

Changes in 0.10.3 [2018.07.02]

Backport the proper fixity for ($!), which was accidentally omitted in base-compat-0.10.2.

Changes in 0.10.2 [2018.07.02]

Sync with base-4.12/GHC 8.6
Backport RuntimeRep-polymorphic versions of ($!) and throw to Prelude.Compat and Control.Exception.Compat, respectively (if using base-4.10/GHC 8.2 or later).
Introduce the Data.Functor.Contravariant.Compat module, which reexports Data.Functor.Contravariant if using base-4.12/GHC 8.6 or later.

See Data.Functor.Contravariant.Compat in the corresponding base-compat-batteries release for a version with a wider support window.

Changes in 0.10.1 [2018.04.10]

Add Data.List.NonEmpty.Compat.
Reexport (Data.Semigroup.<>) from Data.Monoid.Compat back to base-4.9.

Changes in 0.10.0 [2018.04.05]

Sync with base-4.11/GHC 8.4
Backport Semigroup((<>)) to Prelude.Compat.

Note that the Semigroup class has only been in base since base-4.9/GHC 8.0, so accordingly, this can only be backported back to GHC 8.0. If you wish to have a version of Prelude.Compat that backports Semigroup to older GHCs (by conditionally depending on the semigroups library), use the Prelude.Compat module from the base-compat-batteries package.
Backport (<&>) to Data.Functor.Compat
Backport iterate' to Data.List.Compat
Backport showHFloat to Numeric.Compat
Backport a RuntimeRep-polymorphic withTypeable function to Type.Reflection.Compat. (This is only exported on base-4.10/GHC 8.2.)
Introduce the following modules, back until the oldest version of base that can support backporting them. If you wish to use them in conjunction with older versions of base, use the base-compat-batteries package.
- Control.Monad.Fail.Compat (back until base-4.9/GHC 8.0)
- Control.Monad.IO.Class.Compat (back until base-4.9/GHC 8.0)
- Data.Bifunctor (back until base-4.8/GHC 7.10)
- Data.Bifoldable and Data.Bitraversable (back until base-4.10/GHC 8.2)
- Data.Functor.Compose.Compat, Data.Functor.Product.Compat, and Data.Functor.Sum.Compat (back until base-4.9/GHC 8.0)
- Data.Functor.Identity.Compat (back until base-4.8/GHC 7.10)
- Data.Semigroup.Compat (back until base-4.9/GHC 8.0)
- Data.Void.Compat (back until base-4.8/GHC 7.10)
- Numeric.Natural.Compat (back until base-4.8/GHC 7.10)
Introduce versions of modules with the suffix .Repl. These simply reexport the contents of their counterparts without the .Repl suffix to provide a globally unique namespace to import from in the event one wants to import base-compat modules into GHCi. (In base-compat-batteries, the corresponding suffix is .Repl.Batteries.)
