On September 21st, 2026, we began maintenance updates of Apigee instances configured for maintenance windows.

If you set a preferred window for maintenance for your instance, and your instance version is below 1-18-0-apigee-4, your instance will be updated to 1-18-0-apigee-4 within the next seven to 21 days. A notification containing the expected date of upgrade will be sent within the next two business days.

Note: Instances that meet either of the following two criteria will not be updated:

• Your instance has a DNS misconfiguration, as described in Known Issue 445936920.
• Your instance uses an Apigee Java Library that has been removed, as described in Apigee release notes dated October 16, 2025.
