The Batch Debian 11 operating system (OS) image family has reached end of development due to the end of support (EOS) for Compute Engine Debian 11 images on August 31, 2026. The last Batch Debian 11 images—any image versions with the batch-debian-11-official prefix—are only supported until August 31, 2026. Before then, migrate any job that uses a Batch Debian 11 image to a Batch Debian 12 image (or other image) as follows:

• For job definitions that use the batch-debian image prefix (which is the default image for jobs with any script runnables), the image that Batch automatically selects during job creation is gradually migrating to Debian 12 no later than August 31, 2026. For any jobs created before August 31, 2026, you can check whether the job uses Debian 11 or Debian 12 by describing the job.
• For job definitions that specify either the batch-debian-11-official image family or an image version with that prefix, specify a different image during job creation. For example, to migrate to Debian 12, specify either the batch-debian-12-official image family or an image version with that prefix.
