Shield Changelog

Mon, 09 Nov 2026 15:40:00 +0100

This page lists the changes to Relution Shield for each version released as the Docker image relution/relution-shield on Docker Hub. Installation and configuration are described in Relution Shield →.

Available versions

The 2-latest tag used in the installation guide currently points to version 26.1.0 (as of 9 November 2026). Newer versions are referenced by their version number in the image, for example relution/relution-shield:26.3.1.

Version 26.3.1

2026-11-04

Updates

Connections without EAP or XAuth authentication are rejected. The device ID is determined exclusively from the EAP identity and no longer from the IKE identity. The example configurations for iOS and Android Enterprise use EAP and are not affected
Device IDs are checked against a fixed format before the access check (4 to 64 characters, letters, digits, - and _); other IDs are rejected
New environment variable ACCESS_CHECK_FAIL_OPEN (default true) defines whether devices with a valid certificate are accepted when their status cannot be determined. It replaces RELUTION_SERVER_NOT_REACHABLE_ALLOW_DEVICE; the previous name is still evaluated as long as ACCESS_CHECK_FAIL_OPEN is not set
New environment variable DEVICE_COMPLIANCE_DIR for the directory inside the container in which the compliance status is cached (default /opt/strongswan/compliance)
Control characters are removed from the peer identities before they are written to the log
Security improvements and hardening

Fixes

A response from the Relution server that cannot be evaluated, such as a proxy error page, is treated like an unreachable server and follows the ACCESS_CHECK_FAIL_OPEN setting
If the compliance status cannot be cached, the result returned by the Relution server still applies

Version 26.3.0 was not released on Docker Hub; its changes are included in 26.3.1.
