# 2025 10 20

<Update label="October 20, 2025" description="Activity log, interactive protocol graphs, and MSMR validation">
  ## Activity log

  Studio now tracks optimization and data fit usage in a new activity log, giving teams visibility into how resources are being used across the organization.

  ## Interactive protocol visualization

  Protocols can now be visualized as interactive graphs, making it easier to understand complex multi-step protocols at a glance.

  ## MSMR validation framework

  Introduced an MSMR OCP validation framework, enabling validation plots to be rendered directly in Studio.

  <AccordionGroup>
    <Accordion title="Studio">
      **Improvements**

      * Updated data fit UI with parameter progress plots in an accordion and a smoother loading experience.
      * Added UCP time series upsampling with linear interpolation.
      * Adaptive time steps for UCP simulations to prevent timeout issues.
      * Improved error messages in pipelines with more detailed error handling.
      * Improved checkpoint serialization for numerical results.

      **Fixes**

      * Fixed simulations not rerunning when the cached job had failed.
      * Fixed EIS step causing all subsequent Time values to be NaN.
      * Fixed parameterization validation plot and various UI issues.
      * Fixed duplicate time value handling using new PyBaMM solvers.
    </Accordion>

    <Accordion title="Pipeline">
      **Improvements**

      * Refactored validation so objectives own their validations.
      * Improved reporting of the best fit result to Studio.
      * Added standardized parameter and field naming.
      * Added HighSide/LowSide constraint metrics and Maximum aggregation.
      * Generalized the multi-step fast charge example.

      **Fixes**

      * Fixed sign errors in SingleElectrodeLumpedSPMR.
      * Changed lumped SPMR sign convention to be more intuitive.
