1.2

Release corresponding to lens-aeson-1.2 API changes.

• Require aeson-2.0.3.* and optics-core-0.4.1 or greater.

• Drop support for GHC-8.0

• Change the types of _Object, key, and members:

  -_Object :: Prism' t (HashMap Text Value)
  +_Object :: Prism' t (KeyMap Value)
  
  -key :: AsValue t => Text -> AffineTraversal' t Value
  +key :: AsValue t => Key  -> AffineTraversal' t Value
  
  -members :: AsValue t => IndexedTraversal' Text t Value
  +members :: AsValue t => IndexedTraversal' Key  t Value
  

  This mirrors similar changes made in aeson-2.0.*, where the type of Object's field was changed from HashMap Text Value to KeyMap Value.

  The Ixed Value instance changes similarly:

  -type instance Index Value = Text
  +type instance Index Value = Key
  

• Remove Primitive and AsPrimitive, since https://tools.ietf.org/html/rfc7159 de-emphasized the notion of primitive versus composite JSON values.

  • The AsPrimitive methods (_Value, _String, and _Bool) are now AsValue methods.
  • _Number's default signature, Bool_, String_, and Null_ now have an AsValue constraint.

• Add an IsKey class, whose method _Key is an Iso for converting values to and from a Key.

1.1.1

• Support aeson-2.0.0.0: add instances for KeyMap.
