## Announcement Announcement On March 19th, 2026, we began maintenance updates of Apigee instances [configured for maintenance windows](https://cloud.google.com/apigee/docs/api-platform/system-administration/maintenance-windows). If you set a preferred window for maintenance for your instance, and your instance version is below **1-16-0-apigee-6**, your instance will be updated to **1-16-0-apigee-6** 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](https://cloud.google.com/apigee/docs/release/known-issues). * Your instance uses an Apigee Java Library that has been removed, as described in [Apigee release notes dated October 16, 2025](https://cloud.google.com/apigee/docs/release/release-notes#October%5F16%5F2025).
