+## [4.0.1] - 2021-01-30
+
+### Added
+    - SDK up to date with API v1.0.183
+    - Cookie options configuration to set path - defaults to root path if no path is provided.
+
+### Fixed
+    - Prevent list options from being mutated. This lead to side effects for any user relying on the options object
+    - Typescript only: list options `searchOn` and `sortBy` would produce type errors for valid types
