<Update label="November 3, 2025" description="Create model from pipeline, reusable data grid, and ECM with arbitrary RC pairs">
  ## Create model from pipeline

  You can now create a model directly from a pipeline, opening the model creator pre-filled with the pipeline's parameters in read-only mode. This streamlines the workflow from fitting to simulation.

  ## Reusable data grid across Studio

  All tables in Studio now share a consistent browsing experience with built-in search, filtering, and configurable columns.

  ## ECM with arbitrary RC pairs

  The pipeline now supports equivalent circuit models with an arbitrary number of RC pairs, integrated with the lumped single electrode SPMR. This enables more flexible impedance-based modeling.
