🟦 Blueprint component override & defaults, and visualizer override for all views
- Component defaults: Configure default component value for an entire view, used when no values are logged to the data store (using rr.log()).
- Component overrides: Specify a value to use regardless of the data-store & default values and use specified value instead. Can be set per view per entity.
- Visualizer overrides: Specify a visualizer to use for a given entity in a given view. Previously only available for scalar data in timeseries views, now available for all view kinds.
- All three are available from the (fully revamped) UI and the Python blueprint APIs.
- Everything that was editable per entity in a view now uses component overrides (e.g. camera plane distance, transform axis lengths, etc.)
- Tip: Tooltips for each component in the UI include a link to the docs now!
🕸️ Improved notebook & website embedding support
- Now you can stream data from the notebook cell to the embedded viewer.
- Much improved support for having multiple viewers on the same web page.
- More configuration options have been added to control the visibility of the Menu bar, time controls, etc.
- Note: Use pip install "rerun-sdk[notebook]" to include the better notebook support. This includes the new rerun-notebook package, which is used internally by [rerun-sdk].
🧑‍🏫 New Examples
🛠️ Improved the logging API with many new and updated archetypes and components (see migration guide)
🖼️ TensorView is now fully configurable from blueprint code
🎛️ Revamped selection panel UI
🚚 Much work is being done under-the-hood to migrate our data-store to "chunks" (aka units of batched data). More on this in the next release!
- SDKs are already using chunks to transport data to the viewer, performance characteristics may have changed but should be largely the same for the moment.

⚠️ Breaking changes

HalfSizes2D has been renamed to HalfSize2D
HalfSizes3D has been renamed to HalfSize3D
.rrd files from older versions won't load in Rerun 0.17
