- FCacheRecord must now be created by FCacheRecordBuilder. - FCacheRecord values are always an opaque buffer now, and ECacheRecordType has been removed. - FCachePayload has been added as a common type for the cache record value and attachments. - FCachePayloadId has been added as a 12-byte identifier for cache payloads. - ICache::GetAttachments is now GetPayloads and can fetch both values and attachments. - ECachePriority::Blocking has been added for requests that the caller will block on. #rb Zousar.Shaker #rnx [CL 15471951 by Devin Doucette in ue5-main branch]
