## 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`.)

## Changes in 0.9.3 [2017.04.10]
 - Sync with `base-4.10`/GHC 8.2
 - Backport `fromLeft`/`fromRight` to `Data.Either.Compat`
 - Backport implementations of `maximumBy`/`minimumBy` which use constant stack
   space to `Data.Foldable.Compat`
 - Backport `asProxyTypeOf` with a generalized type signature to
   `Data.Proxy.Compat`
 - Backport `gcoerceWith` to `Data.Type.Coercion.Compat`
 - Backport `plusForeignPtr` to `Foreign.ForeignPtr.Compat`

## Changes in 0.9.2
 - Allow building on the HaLVM

## Changes in 0.9.1
 - Use the more efficient version of `replicateM` and `replicateM_` introduced
   in `base-4.9`

## Changes in 0.9.0
 - Sync with `base-4.9`/GHC 8.0
 - Weakened `RealFloat` constraints on `realPart`, `imagPart`, `conjugate`,
   `mkPolar`, and `cis` in `Data.Complex.Compat`
 - Backport `Foreign.ForeignPtr.Safe` and `Foreign.Marshal.Safe`
 - Generalize `filterM`, `forever`, `mapAndUnzipM`, `zipWithM`, `zipWithM_`,
   `replicateM`, and `replicateM_` in `Control.Monad` from `Monad` to
   `Applicative`
 - Backport `.Unsafe.Compat` modules (for `Control.Monad.ST`,
   `Control.Monad.ST.Lazy`, `Foreign.ForeignPtr`, and `Foreign.Marshal`)
 - Backport `forkFinally` and `forkOSWithUnmask` to `Control.Concurrent.Compat`
 - Backport `Data.Functor.Const`
 - Backport `modifyIORef'`, `atomicModifyIORef'` and `atomicWriteIORef` to
   `Data.IORef.Compat`
 - `Data.Ratio.{denominator,numerator}` have no `Integral` constraint anymore
 - Backport `modifySTRef'` to `Data.STRef.Compat`
 - Export `String`, `lines`, `words`, `unlines`, and `unwords` to
   `Data.String.Compat`
 - Generalize `Debug.Trace.{traceM, traceShowM}` from `Monad` to `Applicative`
 - Backport `errorWithoutStackTrace` to `Prelude.Compat`
 - Backport `unsafeFixIO` and `unsafeDupablePerformIO` to
   `System.IO.Unsafe.Compat`

## Changes in 0.8.2
 - Backport `bitDefault`, `testBitDefault`, and `popCountDefault` in
   `Data.Bits.Compat` to all versions of `base`
   - Backport `toIntegralSized` to `base-4.7`
 - Backport `nub` and `nubBy` (as well as `union` and `unionBy`, which are
   implemented in terms of them) to fix logic error in `Data.List.Compat`
 - Backport `byteSwap16`, `byteSwap32`, and `byteSwap64` to `Data.Word.Compat`
 - Backport `fillBytes` in `Foreign.Marshal.Utils.Compat`
 - Backport `showFFloatAlt` and `showGFloatAlt` to `Numeric.Compat`

## Changes in 0.8.1.1
 - Fixed Windows build

## Changes in 0.8.1
 - Implement `setEnv` and `unsetEnv` in `System.Environment.Compat` (which were
   ported from the `setenv` package). As a result, `base-compat` now depends
   on `unix` on POSIX-like operating systems.
 - Drop GHC 6.12 (and `base-4.2.0.0`) compatibility

## Changes in 0.8.0.1

   [`base-orphans`](https://github.com/haskell-compat/base-orphans)
