 API redesign in preparation for moving the UI out of centurion to it's [own project](https://github.com/nofusscomputing/centurion_erp_ui). This release introduces a **Feature freeze** to the current UI. Only bug fixes will be done for the current UI.
 
+- A large emphasis is being placed upon API stability. This is being achieved by ensuring the following:
+
+    - Actions can only be carried out by users whom have the correct permissions
+
+    - fields are of the correct type and visible when required as part of the API response
+
+    - Data validations work and notify the user of any issue
+
+    We are make the above possible by ensuring a more stringent test policy.
+
 - New API will be at path `api/v2` and will remain until v2.0.0 release of Centurion on which the `api/v2` path will be moved to `api`
 
 - API v1 is now **Feature frozen** with only bug fixes being completed. It's recommended that you move to and start using API v2 as this has feature parity with API v1.
