# 2026.3.0 Upgrade Notes When upgrading to this version it is important to set the following custom runtime setting on your AppControl server: com.mendix.webui.StateSizeWarningThreshold = 10000 This is needed to prevent excessive warnings in the AppControl system logs. *** New Features \[POLICIES] Data Policy Management AppControl now supports Data Policy management, enabling organizations to classify data and validate module and user roles directly within the platform. \[POLICIES] New Policy Checks Six new policy checks have been added to the platform: (APP\_0014) Data is classified — verifies that entities and attributes in the domain model have been assigned a data classification level. (DOM\_0009) Module roles are validated — checks that module roles are correctly defined and assigned. (APP\_0015) User roles are validated — verifies that user roles are properly configured across the application. (APP\_0007) Anonymous role is restricted — ensures that the anonymous user role does not have excessive access rights. (APP\_0016) Default user role is restricted — validates that the default user role is appropriately restricted. (APP\_0008) System administrator role is restricted — checks that the system administrator role is scoped correctly and not overexposed. *** Improvements \[CORE] Harden Entity Access Entity access has been reviewed and tightened across the platform to improve security posture. \[CORE] Upgrade SAML and SQLite Updated SAML and SQLite dependencies to their latest supported versions for improved security and compatibility. \[POLICIES] Add Re-check Now Option to Revisions Users can now manually trigger a re-check on revisions, providing more control over validation timing. \[CORE] Manually Acknowledge Alerts Users can now manually acknowledge alerts, providing greater control over alert management workflows. *** Resolved Issues \[RELEASES] Deployed revision not updated automatically after release Resolved an issue where the deployed revision was not automatically updated following a successful release. \[RELEASES] Cancel button visible after release completes Fixed an issue where the cancel button remained visible after a release had already completed. \[RELEASES] Build task failing due to long descriptions Resolved an exception that occurred when a build task description exceeded 2000 characters. \[RELEASES] Task scheduling visibility Fixed an issue where task scheduling options were incorrectly visible for on-demand releases. \[TASKS] Multiselect filter for status in task assignment overview The task assignment overview now supports multiselect filtering by status, making it easier to manage and review tasks across multiple states. \[CORE] Reusing Mendix app IDs causes app list update to fail Resolved an issue where reusing Mendix app IDs caused the app list update process to fail. \[CORE] Removing user from user group should not remove rights if in another group Fixed an issue where removing a user from a user group incorrectly revoked rights that were still granted via another group membership. \[POLICIES] DOM\_0005 max entities check not working Resolved an issue where the DOM\_0005 policy check for maximum entities was not functioning correctly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
