- Update th-abstraction to version 0.2.8.0.
  ## 0.2.8.0 -- 2018-06-29
  * GADT reification is now much more robust with respect to `PolyKinds`:
    * A bug in which universally quantified kind variables were mistakenly
      flagged as existential has been fixed.
    * A bug in which the kinds of existentially quantified type variables
      were not substituted properly has been fixed.
    * More kind equalities are detected than before. For example, in the
      following data type:

```haskell
      data T (a :: k) where
        MkT :: forall (a :: Bool). T a
      ```

We now catch the `k ~ Bool` equality.
  * Tweak `resolveTypeSynonyms` so that failing to reify a type constructor
    name so longer results in an error. Among other benefits, this makes
    it possible to pass data types with GADT syntax to `normalizeDec`.

## 0.2.7.0 -- 2018-06-17
  * Fix bug in which data family instances with duplicate occurrences of type
    variables in the left-hand side would have redundant equality constraints
    in their contexts.

-------------------------------------------------------------------
Mon May 14 17:02:11 UTC 2018 - psimons@suse.com

- Update th-abstraction to version 0.2.6.0 revision 1.
  * Fix bug in which `applySubstitution` and `freeVariables` would ignore
    type variables in the kinds of type variable binders.
  * Added `pragLineDCompat`, `newtypeDCompat` and `tySynInstDCompat`
  * Fix bug that caused GADT equality constraints to be incorrect in some cases.
  * Expose `Unpackedness` and `Strictness` (which were unexported by accident).
  * Add `resolvePredSynonyms`
  * Add `reifyConstructor`, which allows reification of `ConstructorInfo` from
    a constructor name, and `lookupByConstructorName`, which allows directly
    looking up a `ConstructorInfo` from a `DatatypeInfo` value for a given
    constructor `Name`.
  * Augment `reifyDatatype` to be able to look up `DatatypeInfo` from the `Name`
    of a record selector for one of its constructors. Also add `reifyRecord` for
    reification of of `ConstructorInfo` from a record name, and
    `lookupByRecordName`, which allows directly looking up a `ConstructorInfo`
    from a `DatatypeInfo` value for a given record `Name`.
  * Fix bug that caused `th-abstraction` to fail on GHC 7.0 and 7.2 when passing
    a vanilla constructor name to `reifyDatatype`
  * Make `normalizeDec` and `normalizeCon` more robust with respect to
    data family instances on GHC 7.6 and 7.8
