Multi-dimensional interpolant editor
The parameter interpolant editor now supports multi-dimensional x values, making it possible to view and edit parameters that depend on more than one variable — such as temperature and SOC — directly in Studio.Find out more →2D interpolant data upload
Users can now upload 2D interpolant data, with the backend automatically interpolating to a regular grid. This simplifies working with experimentally measured parameter surfaces.Find out more →Piecewise interpolation
The pipeline adds piecewise interpolation with both 1D and 2D support, giving more flexibility when fitting parameters with distinct regions of behavior.Find out more →Studio

Improvements
- Added MSMR validation plots for pipelines from the API.
- Improved data fit UI with loading state and timeout handling.
- Fixed error handling for model creation with duplicated names.

Improvements
- Added design objective custom parameters for evaluating by SOC or concentration.
- Added
initial_concentration_from_socfor SOC-based initialization. - Added initialization for lumped SPM with SOC calculation from voltage.
- Allow additional arguments in data fit for cost logger and initial guess override.
- MSMR diffusion dUdx tolerance — clip diffusivity in low dUdx regions.
- Refactored Pints optimizers with lighter wrappers and parallel functionality.
- Removed Identity as the default transform in the parameter parser.
