# April 30, 2026 - AI Object Storage lifecycle and bucket cleanup docs

> New docs cover bucket lifecycle policies, aborting incomplete multipart uploads, and emptying and deleting buckets.

The AI Object Storage documentation now includes three new pages that cover bucket lifecycle policies, multipart upload cleanup, and bucket deletion in depth.

## New pages

* [Bucket lifecycle policies](/products/storage/object-storage/buckets/lifecycle-policies) is the reference for supported lifecycle actions (`Expiration`, `NoncurrentVersionExpiration`, `AbortIncompleteMultipartUpload`), key behaviors (creation-time evaluation, UTC day boundary, the lifecycle bypass of `Deny` access policy statements), prefix and tag filters, common configurations, and apply procedures for the AWS CLI, s3cmd, and Boto3.
* [Abort incomplete multipart uploads](/products/storage/object-storage/buckets/abort-multipart-uploads) covers locating incomplete multipart uploads, aborting a single upload, and aborting every incomplete upload in a bucket.
* [Empty and delete a bucket](/products/storage/object-storage/buckets/empty-and-delete-bucket) walks through deleting current objects, noncurrent versions, delete markers, and incomplete multipart uploads, then deleting the empty bucket. Includes guidance on bulk deletion approaches and how to prevent `BucketNotEmpty` errors.

## Updated pages

* [AI Object Storage S3 compatibility](/products/storage/object-storage/reference/object-storage-s3) now opens with **S3 API compatibility notes**, a consolidated section that documents unsupported features (S3 Batch Operations, S3 event notifications, lifecycle `Transition` actions) and the lifecycle bypass of `Deny` access policy statements.
* [Manage AI Object Storage with Terraform](/products/storage/object-storage/use-terraform-aws-provider) documents a known issue in version 0.7.0 of the CoreWeave Terraform provider that silently drops `NoncurrentVersionTransitions`.
* [About bucket access policies](/products/storage/object-storage/auth-access/bucket-access/bucket-policies) and [Manage buckets](/products/storage/object-storage/buckets/manage-buckets) now link to the new lifecycle and bucket-cleanup pages instead of inlining the same content.
