10.7.1 [2021.10.30] 2------------------ 3* Backport new instances from GHC 9.2/`base-4.16` 4 * `Eq1`, `Read1`, and `Show1` instances for `Complex` 5 * `Eq{1,2}`, `Ord{1,2}`, `Show{1,2}`, and `Read{1,2}` instances for `(,,)` 6 and `(,,,)` 7 80.7 [2021.07.25] 9---------------- 10* Backport changes from `transformers-0.6.*`: 11 * Remove the long-deprecated `selectToCont` function from 12 `Control.Monad.Trans.Select`. 13 * Backport various `Generic`, `Generic1`, and `Data` instances. 14 * Backport `handleE`, `tryE`, and `finallyE` to `Control.Monad.Trans.Except`. 15 * Backport explicit implementations of `(<$)`, `liftA2`, `(*>)`, and `(<*)` 16 for `Control.Applicative.Backwards`. 17 * Backport a lazier implementation of `(<*>)` for `Control.Applicative.Lift`. 18 190.6.6 [2020.09.30] 20------------------ 21* Add `FunctorClassesDefault`, an adapter newtype suitable for `DerivingVia`, 22 to `Data.Functor.Classes.Generic`. 23* Fix a bug in which `readsPrec1Default`/`liftReadsPrecDefault` would parse 24 empty data types too strictly. 25 260.6.5 [2019.05.11] 27------------------ 28* Ensure that the backported `MonadFail` instance for `ExceptT` is available 29 when built against `transformers-0.4.*`. 30 310.6.4 [2019.04.01] 32------------------ 33* Use more conservative CPP to guard the backported `MonadFix` instance for 34 `ListT`. 35 360.6.3 [2019.04.01] 37------------------ 38* Backport changes from `transformers-0.5.6.*`: 39 * Backport the `MonadFix` instance for `ListT` in 40 `Control.Monad.Trans.Instances`. 41 * Generalize the type of `except` in `Control.Monad.Trans.Except`. 42* Backport `MonadFail` instances for `AccumT`, `Reverse`, and `SelectT` on 43 pre-8.0 versions of GHC by depending on the `fail` package if necessary. 44* Backport `MonadFail` instances for monad transformer types in 45 `Control.Monad.Trans.Instances`. 46 470.6.2 48----- 49* `transformers-compat` now uses automatic flags instead of manual ones. 50 This has a number of benefits: 51 52 * There is no need for making several simultaneous releases to support each 53 flag combination. 54 * As a result, the `cabal-install` constraint solver should have a much 55 easier time figuring out install-plans involving `transformers-compat`. 56 57 Due to old `cabal-install` bugs, `cabal-install-1.16` and older may have a 58 harder time installing this package, so it is recommended that you use 59 `cabal-install-1.18` or later. (Or, if you must use `cabal-install-1.16` or 60 older, installing `transformers-compat` with the appropriate flags should 61 help.) 62 630.6.1.6 64------- 65* Each of versions 0.6.1.2–0.6.1.6 is a 0.6.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6.1 release notes describe the changes in this version. 66 This release is configured with none of `-ftwo`, `-fthree`, `-ffour`, or `-ffive` (which works with `transformers-0.5.3` and above). 67 680.6.1.5 69------- 70* Each of versions 0.6.1.2–0.6.1.6 is a 0.6.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6.1 release notes describe the changes in this version. 71 This release is configured with `-ffive` (which works with `transformers-0.5` up until, but not including, `transformers-0.5.3`). 72 730.6.1.4 74------- 75* Each of versions 0.6.1.2–0.6.1.6 is a 0.6.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6.1 release notes describe the changes in this version. 76 This release is configured with `-ffour` (which works with the `transformers-0.4` series). 77 780.6.1.3 79------- 80* Each of versions 0.6.1.2–0.6.1.6 is a 0.6.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6.1 release notes describe the changes in this version. 81 This release is configured with `-fthree` (which works with the `transformers-0.3` series). 82 830.6.1.2 84------- 85* Each of versions 0.6.1.2–0.6.1.6 is a 0.6.1 build with a different set of flags configured. Building this way allows us to work around bugs in `cabal`'s backtracker. The 0.6.1 release notes describe the changes in this version. 86 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 87 880.6.1 89----- 90* Fix an oversight in which the `Control.Monad.Trans.Accum` and 91 `Control.Monad.Trans.Select` modules were not backported when built with the 92 `-ffour` flag. 93 940.6.0.6 95------- 96* 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. 97 This release is configured with none of `-ftwo`, `-fthree`, `-ffour`, or `-ffive` (which works with `transformers-0.5.3` and above). 98 990.6.0.5 100------- 101* 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. 102 This release is configured with `-ffive` (which works with `transformers-0.5` up until, but not including, `transformers-0.5.3`). 103 1040.6.0.4 105------- 106* 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. 107 This release is configured with `-ffour` (which works with the `transformers-0.4` series). 108 1090.6.0.3 110------- 111* 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. 112 This release is configured with `-fthree` (which works with the `transformers-0.3` series). 113 1140.6.0.2 115------- 116* 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. 117 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 118 1190.6 120--- 121* 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). 122* 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`. 123* 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. 124* Backport changes from `transformers-0.5.5`: 125 * Backport the `Semigroup` instance for `Constant` 126 * Add `mapSelect` and `mapSelectT` 127 * Define `selectToContT` (and deprecate `selectToCont` in favor of that) 128 * Define some explicit `(*>)` definitions to avoid space leaks 129* Backport changes from `transformers-0.5.4` (i.e., add `Bifoldable` and `Bitraversable` instances for `Data.Functor.Constant`) 130* Backport changes from `transformers-0.5.3`: 131 * Backport the `Control.Monad.Trans.Accum` and `Control.Monad.Trans.Select` modules 132 * Backport the `eitherToErrors` and `elimLift` functions to `Control.Applicative.Lift` 133 * Backport `Bits`, `FiniteBits`, `IsString`, `Num`, `Real`, `Integral`, `Fractional`, `Floating`, `RealFrac`, and `RealFloat` instances for `Data.Functor.Identity` 134 * Backport `Monad`, `MonadFail`, and `MonadPlus` instances for `Data.Functor.Reverse` 135 * Backport `Eq1`, `Ord1`, `Read1`, and `Show1` instances for `Data.Proxy` 136* Backport changes from `transformers-0.5.2` (i.e., add more `INLINE` annotations) 137* Backport changes from `transformers-0.5.1` (i.e., add `Bounded`, `Enum`, `Ix`, and `Storable` instances for `Identity`) 138 1390.5.1.4 140------- 141* 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. 142 This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 143 1440.5.1.3 145------- 146* 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. 152 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 153 1540.5.1 155----- 156* Fix a bug in which `PolyKinds` was enabled on GHC 7.4, resulting in interface file bugs on that version of GHC. 157 1580.5.0.4 159------- 160* 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. 161 This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 162 1630.5.0.3 164------- 165* 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. 166 This release is configured with `-fthree` (which works with the `transformers-0.3` series). 167 1680.5.0.2 169------- 170* 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. 171 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 172 1730.5 174--- 175* Update `transformers-compat` to incorporate changes from the `transformers-0.5` series. These changes include: 176 * The `Data.Functor.Classes` module was completely redesigned. 177 * Modules now have `Safe` or `Trustworthy` annotations. 178 * Data types and type synonyms are poly-kinded when possible. 179* Add `Control.Monad.Trans.Instances`, a module of orphan instances that mimic instances available in later versions of `transformers`. 180 1810.4.0.4 182------- 183* 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. 184 This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 185 1860.4.0.3 187------- 188* 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. 194 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 195 1960.4 197--- 198* Added support for the missing `ExceptT` instances from `mtl`. 199 200 This was not done lightly. While this means that by default incurring a dependency on `transformers-compat` drags in `mtl` when you are 201 using an old `transformers`, it means that users do not have to orphan these instances and permits wider adoption of `ExceptT`. 202 203 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. 204 2050.3.3.4 206------- 207* Versions 0.3.3.2–0.3.3.4 were a successful attempt to fix build problems caused by the cabal backtracker. 208* Each of these is a build with a different set of flags configured. 209 This release is configured with neither `-ftwo` nor `-fthree` (which works with `transformers-0.4` and above). 210 2110.3.3.3 212------- 213* Versions 0.3.3.2–0.3.3.4 were a successful attempt to fix build problems caused by the cabal backtracker. 214* Each of these is a build with a different set of flags configured. 215 This release is configured with `-fthree` (which works with the `transformers-0.3` series). 216 2170.3.3.2 218------- 219* Versions 0.3.3.2–0.3.3.4 were a successful attempt to fix build problems caused by the cabal backtracker. 220* Each of these is a build with a different set of flags configured. 221 This release is configured with `-ftwo` (which works with the `transformers-0.2` series). 222 2230.3.2 224----- 225* This release was a failed (or at least, only partially successful) attempt to fix build problems caused by the cabal backtracker. 226 2270.3.1 228----- 229* `transformers 0.4.1` compatibility 230 2310.3 232--- 233* Added the instances for `Data.Functor.Classes` from `transformers 0.4` 234* Switched `Control.Applicative.Backwards` and `Data.Functor.Reverse` to the split constructor/accessor style from `transformers 0.4`. 235 2360.2 237--- 238* Added the new types and classes from `transformers 0.4` 239 2400.1.1.1 241------- 242* Wrote a better synopsis 243 2440.1.1 245----- 246* Updated to trick `cabal` into building an empty `libHStransformers-compat-0.1.a` on GHC 7.6. 247 2480.1 249--- 250* Repository initialized by pulling the `transformers-0.2` compatibility layer out of `lens`. 251
