Portainer 2.39.5

Known issues

• On Async Edge environments, an invalid update schedule date can be displayed when browsing a snapshot

Known issues with Podman support

• Podman environments aren't supported by auto-onboarding script
• It's not possible to add Podman environments via socket, when running a Portainer server on Docker (and vice versa)
• Support for only CentOS 9, Podman 5 rootful

Changes

• Fixed a 2.39.4 regression where a relative env_file: in a Git stack whose compose file lives in a repository sub-directory was resolved against the project root instead of the compose file's own directory, deploying stacks with an empty environment or failing outright
• Improved Edge tunnel reliability over high-latency links (satellite/VSAT): the server no longer tears down a half-established tunnel on timeout, keep-alive and unlimited background retries were added on the agent, and the ping timeout was raised from 3s to 8s
• Fixed standard users not seeing all of their teams in access control selectors (e.g. when restricting access on a newly created Docker Config), caused by FilterUserTeams incorrectly dropping teams
• Fixed deleting images from the Swarm image list only removing them from a single node instead of every node they exist on
• Fixed a potential block where a Docker stack deployment exceeding the internal 15-minute timeout left the stack stuck in "Deploying" status, preventing further redeployments
• Fixed the environment details view always showing the default poll frequency for Edge environments instead of the saved value
• Upgraded the Alpine base image from 3.23.4 to 3.24.1 to address OS-level package CVEs, including the jq advisories (CVE-2026-32316, CVE-2026-40164 and others)
• Upgraded github.com/containerd/containerd/v2 to 2.2.5 to address the following CVEs:
  • CVE-2026-53488,
  • CVE-2026-53492,
  • CVE-2026-53489,
  • CVE-2026-47262,
  • CVE-2026-50195
