ghc-aeson-0.11.2.0-6.7

- Update to version 0.11.2.0 revision 1 with cabal2obs.

- update to 0.11.2.0
  * Enable PolyKinds to generalize Proxy, Tagged, and Const instances.
  * Add unsafeToEncoding in Data.Aeson.Types, use with care!

- update to 0.11.1.4
  * Fix build with base < 4.8 and unordered-containers < 0.2.6.
  * Add missing field in docs for defaultOptions.
  * Fixes a bug where the hashes of equal values could differ.
  * The only changes are added instances. (0.11.1.0)
    + These are new:
    ToJSON a => ToJSON (NonEmpty a)
    FromJSON a => FromJSON (NonEmpty a)
    ToJSON (Proxy a)
    FromJSON (Proxy a)
    ToJSON b => ToJSON (Tagged a b)
    FromJSON b => FromJSON (Tagged a b)
    ToJSON a => ToJSON (Const a b)
    FromJSON a => FromJSON (Const a b)
    + These are now available for older GHCs:
    ToJSON Natural
    FromJSON Natural
  * This release should be close to backwards compatible with aeson 0.9 (0.11.0.0)
    + Breaking changes:
    Revert .:? to behave like it did in 0.9. If you want the 0.10 behavior
    use .:! instead.
    Revert JSON format of Either to 0.9, Left and Right are now serialized with
    an initial uppercase letter. If you want the names in lowercase you can
    add a newtype with an instance.
    All ToJSON and FromJSON instances except for [a] are no longer OVERLAPPABLE.
    Mark your instance as OVERLAPPING if it overlaps any of the other aeson
    instances.
    All ToJSON and FromJSON instances except for [Char] are no longer
    incoherent, this means you may need to replace your incoherent instances
    with a newtyped instance.
    + Additions:
    Introduce .:! that behaves like .:? did in 0.10.
    Allow HH:MM format for ZonedTime and UTCTime. This is one of the formats
    allowed by ISO 8601.
    Added ToJSON and FromJSON instances for the Version, Ordering, and Natural
    types.
    + Bug fixes:
    JSONPath identifiers are now escaped if they contain invalid characters.
    Fixed JSONPath messages for Seq to include indices.
    Fixed JSONPath messages for Either to include left/right.
    Fix missing quotes surrounding time encodings.
    Fix #293: Type error in TH when using omitNothingFields = True.
