-### Added
-- New feature for the next release.
+## [0.1.1] - 2023-23-11
 
 ### Added
-- Initial release of the project.
+- Introduced `Array.wrap` extension to the `Array` class for more reliable conversion of objects to arrays within the Lennarb router environment. This method ensures consistent array wrapping of single objects and `nil` values.
 
 ### Changed
-- Example change to an existing feature.
+- Refactored the `put_header` method to use the `Array.wrap` method for more predictable header value handling.
+- Renamed methods to have a consistent `assign_` prefix to standardize the API interface:
+  - `put_header` to `assign_header`
+  - `write_body` to `assign_body`
+  - `set_params` to `assign_params`
+  - `update_status` to `assign_status`
 
 ### Deprecated
-- Example feature that will be removed in future releases.
 
 ### Removed
-- Example feature that was removed.
 
 ### Fixed
-- Example bug fix.
 
 ### Security
