Starting with the v26.1.0 release, Materialize releases on a weekly schedule for both Cloud and Self-Managed.
In general, Materialize Cloud uses the following weekly schedule to upgrade all regions to the latest release, the listed times may vary based on operational needs:
| Region | Day of week | Time |
|---|---|---|
| aws/eu-west-1 | Wednesday | 2100-2300 Europe/Dublin |
| aws/us-east-1 | Thursday | 0500-0700 America/New_York |
| aws/us-west-2 | Thursday | 0500-0700 America/New_York |
During an upgrade, clients may experience brief connection interruptions, but the service otherwise remains fully available. Upgrade windows were chosen to be outside of business hours in the most representative time zone for the region.
