This page lists important notes for Longhorn v1.3.0. Please see here for the full release note.

Notes

1. Please ensure your Kubernetes cluster is at least v1.18 and at most v1.24 before upgrading to Longhorn v1.3.0 because the supported Kubernetes version has been updated (>= v1.18 and <= v1.24) in v1.3.0.
2. After the upgrade, the recurring job settings of volumes will be migrated to new recurring job resources, and the RecurringJobs field in the volume spec will be deprecated. [doc]
3. When upgrading from a Longhorn version >= 1.2.0 and <= v1.2.3 to v1.3.0, if your cluster has many backups, you may expect to have a long upgrade time (with 22000 backups, it could take a few hours). Helm upgrade may timeout and you may need to re-run the upgrade command or set a longer timeout. This is a known issue
