Read this summary of the new features, changes, and updated information for your product from Xanadu to Yokohama. Tip: If there were no updates for a release notes section in a certain family release, we included a short note for your reference. For example, if a product did not have any updates in Tokyo, the row says "No updates for this release." ## Important information for upgrading Instance Data Replication to Yokohama Before you upgrade to Yokohama, review these pre- and post-upgrade tasks and complete the tasks as needed. {#dfrn3-instancedatareplication-summary__entry__2} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | Improve the performance and processing efficiency of Instance Data Replication (IDR) by upgrading your replication sets to V2, which uses Hermes Messaging Service. For details, see [Upgrading legacy sets](https://www.servicenow.com/docs/access?context=upgrading-legacy-replication-sets-v2&family=yokohama&ft:locale=en-US). Log rotation is automatically enabled for the Replication Payload Error \[idr_replication_payload_error\] table after the upgrade. By default, the log rotation schedule is comprised of seven shards, with five days for each shard. All log entries in this table created before the upgrade are automatically truncated. | [ ] ## New features Between your current release family and Yokohama, new features were introduced for Instance Data Replication. {#dfrn3-instancedatareplication-summary__entry__8} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | [Scheduled seeding](https://www.servicenow.com/docs/access?context=set-up-scheduled-replication-idr&family=yokohama&ft:locale=en-US) : Replicate data from a producer to a consumer at scheduled times each day.
