<Update label="December 8, 2025" description="Data management for cells, silicon design optimization, and UCP solution save/load">
  ## Comprehensive data management

  Studio now provides a full data management experience for cell specifications, cell instances, and measurements. You can define cell specs, track individual cell instances, and associate measurements — all from a redesigned UI with streamlined navigation.

  ## Silicon design optimization

  The pipeline now supports silicon-based electrode design optimization, including cell mass calculations. This enables end-to-end design studies for cells with silicon anodes.

  ## UCP solution save and load

  Protocol simulation results can now be saved to disk and reloaded later with lazy variable evaluation. This makes it practical to work with large simulation outputs without keeping everything in memory.

      **Fixes**

      * Fixed a bug where some calculation results were not correctly parsed back into the data.
      * Improved error handling for MSMR fits so numerical issues surface clearly instead of failing silently.
      * Cleaned up solver output for a clearer log during fits.
