KNIME Analytics Platform 5.8.0 ​

Release date: October 15, 2025

Important notes ​

Components views: HTML Content Sanitization in Advanced Layout ​

Starting with KNIME Analytics Platform 5.8, HTML code entered in the Advanced Layout section of a component view layout is now sanitized before rendering. This change prevents the use of unsafe HTML elements and attributes. If your component views and data apps include custom HTML content, verify that they display correctly after the upgrade.

Default behavior for encrypt JDBC parameter ​

With the update of Microsoft SQL Server driver to version 13.2.0 (see ticket AP-24218 in the Enhancements section), the default behavior for handling the encrypt JDBC parameter has changed to true in the Microsoft SQL Server Connector node. See the release notes for Microsoft SQL Server JDBC Driver 13.2.0 for more details.
