ECA 3.1.6 Fixes Configuration and Upgrade Issues After Guide Library Addition

The ECA 3.1.6 release addresses configuration, token-handling, and upgrade issues in the 3.1 branch. Drupal.org release notes published on 17 August 2026 list 19 resolved issues and support for Drupal 11.3 and Drupal 12. The maintenance release follows ECA 3.1.5, which introduced new Project Browser and migration-related capabilities one week earlier.

Several 3.1.6 fixes affect typed configuration and sites that rely on token-driven values. The release adds missing configuration schema sections for actions, preserves tokenised numeric values and form-field weights, resolves entity-reference token names, and makes ConfigAction::access() respect authorisation results. It also restores the upgrade path from ECA 2.1 to 3.1, including retry-safe handling when removed plugins are encountered, and restores Drupal 12 compatibility for migration and machine-name validation tests.

ECA 3.1.5, released on 10 August 2026 with 24 resolved issues, added an ECA Guide Library source for Drupal's Project Browser. That release also allowed migration-process events to be restricted by migration ID and destination property, added an extra field for empty content, and removed deprecated HTMX method calls. The Project Browser addition belongs to ECA itself rather than representing a new Project Browser release or an initiative-wide Project Browser capability.
