namespace architectures and reduce the need for additional downstream data transformations see the full documentation here dimension events added functionality to map time series data against physical distance or any other dimension and align timestamped measurements with a physical signal, such as meters traveled on a production line this conversion allows you to view production data not just by time, but also by distance ideal for continuous production processes such as extrusion or steel processing external database event generation added support for generating events directly from external database queries this allows automatic event creation from batch management systems, lims, or other third party databases, reducing reliance on manual configurations parquet export optimized parquet data export by bundling multiple measurements into fewer, larger parquet blocks this improvement minimizes the number of files generated while enhancing compression efficiency for better storage and retrieval performance license rework updated the way licensing is done to allow for more flexibly licensing options this includes the ability to license the historian per organization this allows for more flexible licensing options and better control over the historian's usage there is now also a trial license option available to test factry historian before committing to a license ui/ux
