5+**New features**:
6+
7+* Adds a parameterized parser `jsonWith` that can be used to choose how to handle duplicate keys in objects, thanks to Xia Li-Yao.
8+
9+* Add generic implementations of `FromJSONKey` and `ToJSONKey`, thanks to Xia Li-Yao. Example:
10+
11+```haskell
12+data Foo = Bar
13+ deriving Generic
14+
15+opts :: JSONKeyOptions
16+opts = defaultJSONKeyOptions { keyModifier = toLower }
17+
18+instance ToJSONKey Foo where
19+ toJSONKey = genericToJSONKey opts
20+
21+instance FromJSONKey Foo where
22+ fromJSONKey = genericFromJSONKey opts
23+```
24+
25+**Minor**:
26+* aeson now uses `time-compat` instead of `time-locale-compat`, thanks to Oleg Grenrus.
27+* Prepare for `MonadFail` breakages in GHC 8.8, thanks to Oleg Grenrus.
28+* Require `bytestring >= 0.10.8.1` for newer GHCs to avoid build failures, thanks to Oleg Grenrus.
29+* Support `primitive 0.7.*`, thanks to Adam Bergmark.
