Known Issues
In async Edge environments, browsing a snapshot may display an invalid update schedule date.
Known Issues with Podman Support
Podman environments are not supported by the auto-onboarding script. Adding Podman environments via socket while running a Portainer server on Docker (and vice versa) is not possible. Support is limited to CentOS 9 with Podman 5 running in rootful mode.
What’s New
This release ships a handful of targeted fixes. A regression from version 2.39.4 has been corrected: when a Git stack’s compose file sits in a repository sub-directory and uses a relative env_file:, the path is now resolved against the compose file’s own directory rather than the project root. Previously this led to deployments with an empty environment or outright failure.
Edge tunnel reliability over high-latency links—think satellite or VSAT connections—has been significantly improved. The server no longer tears down a half-established tunnel on timeout; keep-alive and unlimited background retries were added on the agent side, and the ping timeout was raised from 3 to 8 seconds. This means more stable connections in challenging network conditions.
Several other bug fixes are included. Standard users now see all their teams in access control selectors (for instance when restricting access to a newly created Docker Config), fixing an issue where FilterUserTeams incorrectly dropped teams. Deleting images from the Swarm image list now removes them from every node, not just a single one. A potential blocker where a Docker stack deployment exceeding the internal 15-minute timeout left the stack stuck in “Deploying” status has been resolved, preventing redeployment deadlocks. The environment details view now displays the actual saved poll frequency for Edge environments instead of always showing the default.
On the security front, the Alpine base image has been upgraded from 3.23.4 to 3.24.1 to address OS-level package CVEs, including advisories for jq (CVE-2026-32316, CVE-2026-40164 and others). Additionally, the github.com/containerd/containerd/v2 dependency was bumped to 2.2.5, patching the following CVEs: CVE-2026-53488, CVE-2026-53492, CVE-2026-53489, CVE-2026-47262, and CVE-2026-50195.
