  • Admin Server gains maintenance task configuration, sparklines, and a connected mount clients page.
  • Volume Server introduces crash-safe EC operations and fixes for vacuum and replication processes.
  • Grafana metrics dashboard is overhauled for better visibility.

New Features

  • Export per-bucket quota and read-only state metrics
  • Configure maintenance tasks via admin.toml
  • Native sparklines on the admin dashboard
  • Connected Mount Clients page
  • volume.tier.move can move volumes between data centers
