## 4.12.0.0 *TBA*
* Bundled with GHC *TBA*
+ * Fix `Show` instance of `Data.Fixed`: Negative numbers are now parenthesized
+ according to their surrounding context. I.e. `Data.Fixed.show` produces
+ syntactically correct Haskell for expressions like `Just (-1 :: Fixed E2)`.
+ (#16031)
+
* Support the characters from recent versions of Unicode (up to v. 12) in
literals (#5518).
