0.6.0.6 ------- * Each of versions 0.6.0.2–0.6.0.6 is a 0.6 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6 release notes describe the changes in this version. This release is configured with none of `-ftwo`, `-fthree`, `-ffour`, or `-ffive` (which works with `transformers-0.5.3` and above). 0.6.0.5 ------- * Each of versions 0.6.0.2–0.6.0.6 is a 0.6 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6 release notes describe the changes in this version. This release is configured with `-ffive` (which works with `transformers-0.5` up until, but not including, `transformers-0.5.3`). 0.6.0.4 ------- * Each of versions 0.6.0.2–0.6.0.6 is a 0.6 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6 release notes describe the changes in this version. This release is configured with `-ffour` (which works with the `transformers-0.4` series). 0.6.0.3 ------- * Each of versions 0.6.0.2–0.6.0.6 is a 0.6 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6 release notes describe the changes in this version.

Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6 release notes describe the changes in this version. This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 0.6 --- * Introduce the `Data.Functor.Classes.Generic` module, which provides functions that can generically implement methods in the `Eq1`, `Ord1`, `Read1`, and `Show1` classes (without the usual boilerplate involved). * Introduce the `generic-deriving` flag. When enabled, `transformers-compat` will depend on the `generic-deriving` library on older versions of GHC to backport `GHC.Generics` support for `Generic` instances and the machinery in `Data.Functor.Classes.Generic`. * Some instances were present in `Data.Functor.Sum` but not in `Control.Monad.Trans.Instances` (e.g., the `Generic`, `Typeable`, and `Data` instances for `Sum`). This has been fixed. * Backport changes from `transformers-0.5.5`: * Backport the `Semigroup` instance for `Constant` * Add `mapSelect` and `mapSelectT` * Define `selectToContT` (and deprecate `selectToCont` in favor of that) * Define some explicit `(*>)` definitions to avoid space leaks * Backport changes from `transformers-0.5.4` (i.e., add `Bifoldable` and `Bitraversable` instances for `Data.Functor.Constant`) * Backport changes from `transformers-0.5.3`: * Backport the `Control.Monad.Trans.Accum` and `Control.Monad.Trans.Select` modules * Backport the `eitherToErrors` and `elimLift` functions to `Control.Applicative.Lift` * Backport `Bits`, `FiniteBits`, `IsString`, `Num`, `Real`, `Integral`, `Fractional`, `Floating`, `RealFrac`, and `RealFloat` instances for `Data.Functor.Identity` * Backport `Monad`, `MonadFail`, and `MonadPlus` instances for `Data.Functor.Reverse` * Backport `Eq1`, `Ord1`, `Read1`, and `Show1` instances for `Data.Proxy` * Backport changes from `transformers-0.5.2` (i.e., add more `INLINE` annotations) * Backport changes from `transformers-0.5.1` (i.e., add `Bounded`, `Enum`, `Ix`, and `Storable` instances for `Identity`) 0.5.1.4 ------- * Each of versions 0.5.1.2–0.5.1.4 is a 0.5.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.5.1 release notes describe the changes in this version.

Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.5.1 release notes describe the changes in this version. This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 0.5.1 ----- * Fix a bug in which `PolyKinds` was enabled on GHC 7.4, resulting in interface file bugs on that version of GHC. 0.5.0.4 ------- * Each of versions 0.5.0.2–0.5.0.4 is a 0.5 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.5 release notes describe the changes in this version. This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 0.5.0.3 ------- * Each of versions 0.5.0.2–0.5.0.4 is a 0.5 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.5 release notes describe the changes in this version. This release is configured with `-fthree` (which works with the `transformers-0.3` series). 0.5.0.2 ------- * Each of versions 0.5.0.2–0.5.0.4 is a 0.5 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.5 release notes describe the changes in this version. This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 0.5 --- * Update `transformers-compat` to incorporate changes from the `transformers-0.5` series. These changes include: * The `Data.Functor.Classes` module was completely redesigned. * Modules now have `Safe` or `Trustworthy` annotations. * Data types and type synonyms are poly-kinded when possible. * Add `Control.Monad.Trans.Instances`, a module of orphan instances that mimic instances available in later versions of `transformers`. 0.4.0.4 ------- * Each of versions 0.4.0.2–0.4.0.4 is a 0.4 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.4 release notes describe the changes in this version. This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 0.4.0.3 ------- * Each of versions 0.4.0.2–0.4.0.4 is a 0.4 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.4 release notes describe the changes in this version. This release is configured with `-fthree` (which works with the `transformers-0.3` series). 0.4.0.2 ------- * Each of versions 0.4.0.2–0.4.0.4 is a 0.4 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.4 release notes describe the changes in this version. This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 0.4 --- * Added support for the missing `ExceptT` instances from `mtl`. This was not done lightly. While this means that by default incurring a dependency on `transformers-compat` drags in `mtl` when you are using an old `transformers`, it means that users do not have to orphan these instances and permits wider adoption of `ExceptT`. If you absolutely can't stand `mtl` and really want this package to build as valid `Haskell98`, then you can use `cabal install transformers-compat -f-mtl` to avoid incurring the dependency to get these instances. However, that is effectively an unsupported configuration. 0.3.3.4 ------- * Versions 0.3.3.2–0.3.3.4 were a successful attempt to fix build problems caused by the cabal backtracker. * Each of these is a build with a different set of flags configured.
