5+* `tagSingleConstructors`, an option to encode single-constructor types as tagged sums was added to `Options`. It is disabled by default for backward compatibility.
6+
7+* The `cffi` flag is now turned on by default, this means C FFI code is no longer used by default. You can flip the flag to get C implementation.
8+
9+* The `Options` constructor is no longer exposed to prevent new options from being breaking changes, use `defaultOptions` instead.
10+
11+* The contents of `GToJSON` and `GToEncoding` are no longer exposed.
12+
13+* Some INLINE pragmas were removed to avoid GHC running out of simplifier ticks.
