1.2.3 [2023.06.27]

• Use aeson’s decode function in the AsJSON instance for ByteStrings. This allows removing a direct dependency on attoparsec.
• Allow building with aeson-2.2.

1.2.2 [2022.08.11]

• Add atKey :: AsValue t => Key -> Traversal' t (Maybe Value), a variant of key that uses at instead of ix.

1.2.1 [2022.05.07]

• Change the IsKey instances for ByteStrings to use decodeUtf8With lenientDecode instead of decodeUtf8. While these IsKey instances are meant to used for interoperability with aeson values that are UTF-8–encoded, using decodeUtf8With lenientDecode at least ensures that converting a non–UTF-8–encoded ByteString will not crash.

1.2 [2022.03.19]

• Require aeson-2.0.2.* and lens-5.0.* or greater.

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

  -_Object :: Prism' t (HashMap Text Value)
  +_Object :: Prism' t (KeyMap Value)
  
  -key :: AsValue t => Text -> Traversal' t Value
  +key :: AsValue t => Key  -> Traversal' 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 Wrapped and Rewrapped instances for KeyMap. These treat KeyMap v as a wrapper around [(Key, v)]. The order in which the key-value pairs appear in this list is not stable.

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

1.1.3 [2021.11.16]

• Drop support for pre-8.0 versions of GHC.

1.1.2 [2021.10.09]

• Allow building with aeson-2.0.0.0.
• Add Index, IxValue, Ixed, At, and Each instances for KeyMap if building with aeson-2.0.0.0 or later.

1.1.1 [2021.02.17]

• Allow building with lens-5.*.
• The build-type has been changed from Custom to Simple. To achieve this, the doctests test suite has been removed in favor of using cabal-docspec to run the doctests.

1.1 [2019.09.26]

• Generalize the type of _JSON from Prism' t a to Prism t t a b. If you wish to continue to use the less general type, use the newly added _JSON' prism.
• Add pattern synonyms corresponding to the Prisms that lens-aeson provides.
• Fix the test suite on 32-bit architectures.

1.0.2

• Support doctest-0.12

1.0.1

• Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.

1.0.0.5

• Fix tests to work against vector-0.11
• Documentation fixes
• No functional changes since 1.0.0.4

1.0.0.3

• Move lens upper bound to < 5 like the other packages in the family

1

• Module migrated from lens package to Data.Aeson.Lens

0.1.2

• Added members and values

0.1.1

• Broadened dependencies

0.1

• Repository initialized
