You can now use Storage batch operations to update object contexts for multiple objects

## Feature Feature You can now use [Storage batch operations](https://cloud.google.com/storage/docs/batch-operations/overview)to update [object contexts](https://cloud.google.com/storage/docs/object-contexts) for multiple objects in a single job. You can clear all existing contexts from the specified objects, remove contexts with specific keys, or update and insert new context key-value pairs. For more information, see[Create and manage batch operation jobs](https://cloud.google.com/storage/docs/batch-operations/create-manage-batch-operation-jobs). ## Feature Feature [Object contexts](https://cloud.google.com/storage/docs/object-contexts) are now[generally available](https://cloud.google.com/products#product-launch-stages). You can attach key-value pairs to your objects to categorize, track, and search your data. Object contexts are preserved by default during copy, rewrite, and compose operations. You can help control this behavior by using the[dropContextGroups](https://cloud.google.com/storage/docs/json%5Fapi/v1/objects/copy#dropContextGroups)JSON API parameter or by providing new contexts in the request.
