# 5.7.4 ## Release Notes #### April 2026 This patch release resolves several issues affecting campaign management, system operations, and administrative permissions. Key fixes include: * Resolved a permission error that prevented EML files from being uploaded to message templates. * Fixed an issue that caused health checks to fail on patch versions such as 5.7.1 when run from the terminal. * Corrected a problem that prevented administrators from managing their own notification settings. * Fixed an issue where copied campaigns could not be stopped. This release improves platform reliability and restores expected administrative control across several areas of the system. --- # 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.
