 ## Release 1.32.0
 ## Introduction
 * Product name: Open Supply Hub
 * Release date: March 22, 2025
 
+### What's new
+* [OSDEV-1814](https://opensupplyhub.atlassian.net/browse/OSDEV-1814) - Added toggle switch button for production location info page to render additional data if necessary. If toggle switch button is inactive (default behavior), additional data won't be send to the server along with name, address and country.
+
 ### Bugfix
 * [OSDEV-1806](https://opensupplyhub.atlassian.net/browse/OSDEV-1806) - Refactored the Parent Company field validation. The field is now validated as a regular character field.
 * [OSDEV-1787](https://opensupplyhub.atlassian.net/browse/OSDEV-1787) - The tooltip messages for the Claim button have been removed for all statuses of moderation events on the `Contribution Record` page and changed according to the design on `Thanks for adding data for this production location` pop-up.
