As a result, any attempt to look up this related relationship would return (incorrectly) 0 records. This included in Workflows and on the Record page. With this release, a migration will automatically run to resolve the invalid indexes. ### Module features no longer disconnect syncs Prior to this update, clicking "save" on a module feature would automatically disconnect syncs not required by any module feature, which could result in incorrect settings. Now, Middle merely warns about potentially invalidly-on syncs instead. ### Fixing search by email Prior to this update, searching by email could result in 0 records incorrectly. This was due to how "@" symbols were interpreted by the underlying ElasticSearch storage engine. This issue is now resolved. ### Several UI fixes * We now properly warn users when trying to navigate away from the edit variables page on Workflows, when there is unsaved work. * Resolved several issues with color consistency, margins, and other style issues throughout the product. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.middle.app/middle-docs/release-notes/august-31-2026.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
