Deprecated

This `update()` with a nullable `where` parameter will be removed in future releases. Please leave a comment on [YouTrack](https://youtrack.jetbrains.com/issue/EXPOSED-494/Inline-DSL-statement-and-query-functions) with a use-case if a nullable condition cannot be replaced with the new `update()` overloads.

Replace with

update(limit = limit) { body.invoke() }
