• Snakemake:
  • Simplified storage handling by removing the need for storage.latch structure in Snakemake workflows.
• Plots
  • New default notebook connection behavior:
    • Previously, once a machine is allocated and spun up for a notebook, the notebook will enter a “Connected” stage and then auto-run all cells from top to bottom. The auto-running behavior can be confusing when you deliver the notebook to a scientist as an application because the widgets and plots are still interactive.
    • Now, the notebook will only enter the “Connected” stage when it has finished auto-running all cells from top to bottom. This ensures that scientists can only interact with a notebook when it’s fully set up.
  • Bug fixes:
    • “Clear all widgets, tables, plots” button no longer disconnects notebook session.
    • Working “+ Plot” icon on Analysis Cells that already has plots displayed
  • Cleaner outline: The sidebar is now collapsible based on the markdown headers in Python cells.
  • Add a “Shape by column” option to the no-code plot configuration.
• Analysis packages for kit providers:
  • Analysis package versioning
  • Ability to delete package
  • Packages — Add columns/ metadata to the packages page
• Pods:
  • Added G6e GPU instances support for both pods and workflows.
  • Improved speed performance for the following common usage patterns with /ldata FUSE
    • Reading files with pandas (pd.read_csv)
    • Creating directories (os.makedirs)
    • Save to a CSV from pandas
