+
+Previously, the {productname} autocorrect plugin depended on a server-side spelling service to retrieve its list of autocorrect entries. This setup increased server load and introduced latency due to REST API calls. As of {release-version}, the autocorrect list has been relocated to the client side, eliminating the need for a spellchecker server. This change improves performance by enabling caching and bundling of the autocorrect functionality with other client-side assets, resulting in faster load times and reduced backend dependencies.
