Change Logs

Version: 1.12.3-bp151.1.11
* Sun Feb 10 2019
- Update generic-deriving to version 1.12.3.
  [#] 1.12.3 [2019.02.09]
  * Support `template-haskell-2.15`.
  * Add a `gshowList` method to `GShow`, which lets us avoid the need for
    `OverlappingInstances` in `Generics.Deriving.TH`. As a consequence, the
    `GShow String` instance has been removed, as it is now fully subsumed by
    the `GShow [a]` instance (with which it previously overlapped).
  * Functions in `Generics.Deriving.TH` now balance groups of `(:*:)` and `(:+:)`
    as much as possible (`deriving Generic` was already performing this
    optimization, and now `generic-deriving` does too).
  * Add a `Generics.Deriving.Default` module demonstrating and explaining
    how and why to use `DerivingVia`. There is also a test suite with
    further examples.

- Cosmetic: replace tabs with blanks, strip trailing white space,
  and update copyright headers with spec-cleaner.
* Fri Jul 13 2018
- Update generic-deriving to version 1.12.2.
  [#] 1.12.2 [2018.06.28]
  * Backport the `Generic(1)` instances for `Data.Ord.Down`, introduced in
    `base-4.12`. Add `GEq`, `GShow`, `GSemigroup`, `GMonoid`, `GFunctor`,
    `GFoldable`, `GTraversable`, and `GCopoint` instances for `Down`.
  * Refactor internals using `th-abstraction`.
  * Adapt to `Maybe` moving to `GHC.Maybe` in GHC 8.6.
* Mon May 14 2018
- Update generic-deriving to version 1.12.1 revision 1.
  * Adapt to the `EmptyDataDeriving` proposal (introduced in GHC 8.4):
  * `Generics.Deriving.TH` now derives `to(1)` and `from(1)` implementations
    for empty data types that are strict in the argument.
  * Introduce an `EmptyCaseOptions` field to `Options` in
    `Generics.Deriving.TH`, which controls whether generated `from(1)`/`to(1)`
    implementations for empty data types should use the `EmptyCase` extension
    or not (as is the case in GHC 8.4).
  * Add `mkFrom0Options`, `mkFrom1Options`, `mkTo0Options`, and `mkTo1Options`
    functions to `Generics.Deriving.TH`, which take `EmptyCaseOptions` as
  * The backported instances for `V1` are now maximally lazy, as per
    `EmptyDataDeriving`. (Previously, some instances would unnecessarily force
    their argument, such as the `Eq` and `Ord` instances.)
  * Add instances for `V1` in `Generics.Deriving.Copoint`, `.Eq`, `.Foldable`,
    `.Functor`, `.Show`, and `.Traversable`.
  * Remove the bitrotting `simplInstance` function from `Generics.Deriving.TH`.
Version: 1.11.2-bp150.2.4
* Thu Aug 03 2017
- Updated with latest spec-cleaner version 0.9.8-8-geadfbbf.
* Wed Apr 19 2017
- Update to version 1.11.2 with cabal2obs.
* Fri Apr 07 2017
- Update to version 1.11.1 revision 1 with cabal2obs.
* Thu Sep 15 2016

Version: 1.10.5-2.5
* Sun Jul 10 2016
- Update to version 1.10.5 revision 0 with cabal2obs.
* Sun Jun 19 2016
- update to 1.10.5
  * Apply an optimization to generated to(1)/from(1) instances that factors
    out common occurrences of M1
  * Export internal typeclass names
  * Fix Haddock issues with GHC 7.8
* Mon May 23 2016
- update to
  * Fix Haddock parsing issue on GHC 8.0
  * Backported MonadPlus and MonadZip instances for U1, and made the Functor,
    Foldable, Traversable, Alternative, and Monad instances for U1 lazier to
    correspond with base-4.9
  * Backported Enum, Bounded, Ix, Functor, Applicative, Monad, MonadFix, MonadPlus,
    MonadZip, Foldable, Traversable, and Data instances (introduced in base-4.9)
    for datatypes in the Generics.Deriving.Base module
  * Added Generics.Deriving.Semigroup
  * Added GMonoid instance for Data.Monoid.Alt
  * Fixed a bug in the GEnum instances for unsigned Integral types
  * Added Safe/Trustworthy pragmas
  * Made instances polykinded where possible
  * On GHC 8.0 and up, Generics.Deriving.TH uses the new type literal-based machinery
  * Rewrote the Template Haskell code to be robust. Among other things, this fixes
    a bug with deriving Generic1 instances on GHC 7.8, and makes it easier to
    derive Generic1 instances for datatypes that utilize GHC 8.0's
  - XTypeInType extension.
  * Added deriveAll0 and makeRep0 for symmetry with deriveAll1 and makeRep1
  * AddedmakeRep0FromType and makeRep1FromType to make it easier to pass in the type
  * Added functions with the suffix -WithKindSigs to allow generating type synonyms
    with explicit kind signatures in the presence of kind-polymorphic type
    variables. This is necessary for some datatypes that use -XTypeInType to have
    derived Generic(1) instances, but is not turned on by default since the TH
    kind inference is not perfect and would cause otherwise valid code to be
    rejected. Use only if you know what you are doing.
  * Fixed bug where a datatype with a single, nullary constructor would generate
    incorrect Generic instances
  * More sensible GEnum instances for fixed-size integral types
  * Added GCopoint, GEnum, GEq, GFoldable, GFunctor, GMonoid, GShow, and GTraversable
    instances for datatypes introduced in GHC 8.0
  * Backported Generic(1) instances added in GHC 8.0. Specifically, Generic instances
    for Complex (base-4.4 and later) ExitCode, and Version; and Generic1 instances
    for Complex (base-4.4 and later) and Proxy (base-4.7 and later). Added GEnum,
    GEq, GFoldable, GFunctor, GIx, GShow, and GTraversable instances for these
    datatypes where appropriate.
