KNIME Analytics Platform 5.3.0 ​

Release date: July 10, 2024

Release notes ​

Updates and compatibility ​

  • In-app upgrades from KNIME Analytics Platform 5.2 are supported
  • KNIME Analytics Platform 5.3 allows switching between Modern UI and the Classic UI without having to close and reopen workflows. In future versions, this will change in order to reduce technical complexity and pave the way for further enhancements of the Modern UI
  • Requirements:
    • KNIME Analytics Platform 5.3 requires KNIME Hub 1.9 or newer
    • KNIME Analytics Platform 5.3 must not be used as executor on KNIME Server 4.16.x or before. KNIME Server 4.17 with full compatibility will be released soon.
  • Compatibility:
    • The “Excel Reader” node might produce slightly different results when processing special xlsx files with array formulas and the re-evaluate formulas option checked. In KNIME Analytics Platform 5.2 certain formulas would evaluate to missing cells and now evaluate to “0”, like in Excel
    • Text Processing: The “Tika Parser” node might produce slightly different results when processing documents with inline images. The reason is an update of the underlying Apache Tika library from version 1.26.0 to 2.9.1
    • Hadoop 3.x upgrade might require updating the Hadoop settings within KNIME Analytics Platform
    • Workflows running on Spark 3.3 and earlier require installation of the new Sparkling Water legacy plugin
    • Eclipse Birt was updated to the most recent version (4.15), which might scale images differently if scaling is defined in %. See the Eclipse Birt ticket description for details.
  • End-of-life:
    • Sparkling Water with Spark 3.4 and later will no longer be supported
    • Existing workflows running on Spark 3.3 and earlier require the new Sparkling Water legacy extension
    • Hive 2 and earlier will no longer be supported out of the box, users must register their own driver
  • Updates:
    • Eclipse 2024-03 (underlying framework), to be "up to date" and to address known CVEs
    • Many third-party library updates (for more information see Preview of KNIME Analytics Platform 5.3.0)
    • Spark 3.5 support
    • Hadoop 3.x support
    • MongoDB driver updated to 5.1.1 to support latest MongoDB versions
    • Hive driver updated to 3.x to support latest version
    • Update of various built-in drivers and flagging of no longer supported DB drivers

For node developers only: (API) Interface definitions for datetime related types were moved to a more central place (org.knime.core), e.g. org.knime.core.data.time.localdate.LocalDateValue.

Known Issues ​

  • Reporting:
    • Fonts of reports might be incorrect if a component that produces a report has been saved in an executed state before updating to 5.3. Re-executing the component will solve the problem.
