Amazon OpenSearch Service now supports in-place volume increases for all volume sizes

[Amazon OpenSearch Service](https://aws.amazon.com/opensearch-service/) now extends in-place cluster volume size increases to volumes exceeding 3 TiB. With this enhancement, you can scale storage capacity across all volume sizes without requiring a blue/green deployment. Previously, you could perform volume increases up to 3 TiB on your clusters without a blue/green deployment. This release removes that limitation, making it easier for you to scale up quickly even beyond 3 TiB when required. Domains that already have a volume size above 3 TiB will require a blue/green deployment the first time a volume increase is made; subsequent volume increases will not require a blue/green deployment. Decreasing storage volume size, or making volume increases within short intervals, will still require a blue/green deployment. You can use the [dry-run](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/managedomains-configuration-changes.html#dryrun) option to check whether your change requires a blue/green deployment. This feature is available in all AWS Commercial and AWS GovCloud (US) Regions where Amazon OpenSearch Service is available.
