-1.11.0 (March 27, 2023)
+1.11.0 (April 3, 2024)
  - Added `sideEffects: false` property in the package.json file to allow tree shaking.
  - Updated Redux-Thunk peer dependency range to include redux-thunk@3.x.x.
  - Updated the build process and added the `tslib` package as an explicit dependency to import TypeScript helpers, thereby avoiding duplicated helper code in the output files.
