Upgrade Window

Your organization will be picked up for upgrade on a rolling basis between 10:00 UTC and 14:00 UTC (06:00 EDT and 10:00 EDT) beginning on 7 October 2026.

Once the upgrade starts, it'll take about 20 minutes to complete.

Action Required

Once your Cribl upgrade is finished, log in to your account and launch Cribl Stream or Cribl Edge (if applicable to your installation). You’ll only need to click Deploy if the upgrade requires it. The application interface will clearly indicate if deployment is necessary.

If you have not yet enabled auto-upgrade on your hybrid Workers, manually upgrade them to 4.20.2 to ensure compatibility.
