2026.4

Changes

This release addresses a regression in the nfs-server image and introduces significant enhancements to deployment orchestration and environment management.

Fix EE-1846 list-images fails

• deploy-cli: Restored the command to nfs-server VM images. It was previously omitted in releases 2026.2 and 2026.3. This had no impact on existing servers.

Improvements to ComposeUp

• Project names are now inferred from compose.yaml (manual override still supported).
• Now runs natively within the project directory rather than using explicit –file flags.
• Added support for environment specification and AWS Secrets Manager to match ContainerRun logic.
• Generated environment variables are persisted to a local .env file for subsequent command use.

Deployment with managed clusters

• run-deploy-and-cleanup: Now supports managed clusters via a cluster key in /var/www/deploy/conf.yml.
• Maintenance Mode: Add enter_maintenance: true to conf.yml to toggle maintenance mode during the deployment lifecycle when using managed clusters.
• Hook lifecycle for managed clusters:
  1. App enters maintenance mode (optional)
  2. “Started” hooks execute
  3. New deployment activates
  4. “Verified” hooks execute
  5. App exits maintenance mode (optional)
• Compatibility: When using managed clusters, blue-green-deploy is no longer supported and legacy conf.yml attributes are ignored.
