Datasets now refresh on one schedule, read faster, and keep connector credentials in a locked vault.

• One schedule per dataset. Every dataset now refreshes on its own schedule, and a dashboard's schedule is its datasets' schedules. New durable datasets get a daily 08:00 refresh in your workspace's timezone, and changing the workspace timezone moves each schedule to the new zone.

• Schedule controls on dashboards. The dashboard menu reads and sets its datasets' schedules, and Resume turns each paused dataset back on. Refresh now works while a schedule is paused, and datasets on a dashboard in an error state keep refreshing on schedule.

• Faster dataset reads. Repeat reads are served from the CDN, and a query already answered over the same dataset version comes from a cache, so dashboards that reuse data load quicker. Datasets are stored in smaller files, and expired scratch datasets are cleaned up within 10 minutes.

• Legacy chart and metric configs removed. The few remaining charts and metrics still on the old config format show the rebuild card.
