✨ Overview & highlights

💽 Tagged components

Starting with 0.22 Rerun began storing additional meta-information for each component,
identifying its field name (e.g. vertex_colors) and its archetype (e.g. Mesh3D).
We finally concluded this effort and made all parts of the Viewer and API aware of this.

While this is mostly about under-the-hood changes, this has a lot of surface level benefits:

• You can now log the same component type multiple times on a single entity path.
  For example, logging multiple archetypes which use the Color component onto the same entity was possible before, but the colors would have overwritten each other:

rr.log("path", rr.GeoPoints(lat_lon=[some_coordinate], colors=[0xFF0000FF]))
rr.log("path", rr.Points2D(positions=[0.0, 0.0], colors=[0x0000FFFF]))
rr.log("path", rr.Mesh3D(vertex_positions=vertices, vertex_colors=[0x00FF00FF]))

• The UI now groups by archetype everywhere and will show the same field names you use in the logging SDKs
  
• Better blueprint defaults: component defaults are now per archetype field and not per type. Making them a lot more useful.
  
• No more indicator components! These showed previously up in the UI and needed special handling for some advanced use cases.

🎥 Video streams

Rerun previously supported video only in the form of MP4 files,
so it was not possible to stream live encoded video to Rerun.
The new VideoStream archetype remedies that!

If you already have encoded video frames, it is just as easy as logging images now:

rr.set_time("time", duration=float(packet.pts * packet.time_base))
rr.log("video_stream", rr.VideoStream(codec=rr.VideoCodec.H264, sample=bytes(packet)))

For now, we only handle H.264, but support for more codecs is on the roadmap.
Learn more on the updated video reference page.

😎 Light mode

Rerun finally has a light mode.

The theme defaults to your OS's setting, but can be adjusted in the settings menu.

🔀 Multi sink

Previously, the SDK's recording stream could only send to one sink at a time.
We now expose the ability to set multiple sinks at once, so you can simultaneously
stream to both the Viewer and a file.

Here's what that looks like in Python (but the API is available in C++ & Rust as well!)

rr.set_sinks(
    # Connect to a local viewer using the default URL
    rr.GrpcSink(),
    # Write data to a `data.rrd` file in the current directory
    rr.FileSink("data.rrd"),
)

🤖 Built-in URDF data loader

You can now log URDF files directly to Rerun using the log_file API.

👀 Other highlights in short

• New Cylinder archetype
• AnyValues utility for Rust
• rerun rrd stats for retrieving statistics about rrd files
• rerun rrd route command to manipulate .rrd files on transport level
• Much faster & better compaction for both rerun rrd compact and automatic in-Viewer compaction
• Viewers started with spawn use now less memory since it no longer sets up an GRPC server for message forwarding
• View3D's eye control type & speed can now be changed from blueprint (and as such is persisted over session!) more properties will follow in the future. (thanks to @jccampagne)

✨ Overview & highlights

• New CLI tool to migrate .rrd files
• Various bugfixes

.rrd migration tool

With 0.23, we made several breaking changes that resulted in older .rrd files not being able to load at all anymore.
To help smoothen the migration to 0.23, we're introducing a migrate command to the Rerun CLI:

rerun rrd migrate colmap.rrd arkit.rrd rgbd.rrd

The command will copy the contents into a .backup file, and then migrate the file.

Due to the incompatibility between .rrd files from 0.23 and those from earlier versions, this command likely
won't be able to migrate every recording perfectly. We expect the migration to work on files between 0.20 and 0.22,
simpler recordings may work as far back as 0.18.

We plan to use this command future .rrd migrations as a way to fulfill our N+1 compatibility guarantee:

• Viewers after 0.23 will always be able to load recordings from the previous version.
• Recordings from 0.23 and beyond may be migrated to the next version.

We currently have no plans for compatibility or migrations across multiple versions.

✨ Overview & highlights

Viewer

• ⏩ New .rrd format that will be backwards compatible
• 📈 Support for multiple scalars under a single entity
• ↪️ Callbacks API for notebooks and JavaScript
• ⚙️ New APIs for attaching properties (metadata) to recordings
• 🧮 Experimental support for tables and dataframes

Multiple scalars under a single entity

In this release we have added support for logging scalar data with multiple signals, under the same entity. This allow you to log data that inherently belongs together, such as the action values in a LeRobot dataset or gyroscope measurements, under the same entity path.

As part of this update, we're deprecating the SeriesLine/SeriesPoint/Scalar archetypes in favor of the plural versions SeriesLines/SeriesPoints/Scalars, for consistent naming with the other archetypes.

For example, the x, y and z component of a gyroscope measurement, previously would be logged as separate entities:

rr.log("gyroscope/x", rr.Scalar(measurement[0]))
rr.log("gyroscope/y", rr.Scalar(measurement[1]))
rr.log("gyroscope/z", rr.Scalar(measurement[2]))

Now can be logged under a single entity:

rr.log("gyroscope", rr.Scalars(measurement))

See the new IMU signals example for more

The SeriesLine and SeriesPoints archetypes now include a visible_series component that lets you control which series appear in your visualizations. Unlike the regular entity visibility property, hidden series will still show up in the legend.

Callbacks API for notebooks and JavaScript

We've added a (limited) API with callbacks, useable from JavaScript and from Notebooks (but not yet from out logging SDKs).

With this you can easily write simple annotations tools.
We've created an example for this using Gradio at https://github.com/rerun-io/annotation-example.

Recording properties

For this release, we have improved Rerun's logging capabilities. There is a new recording properties concept in all of our APIs.
Recording properties allow you to attach metadata to a recording.
For example, you can now change the name of your recording via .send_recording_name("My episode"), which will show up in the recording panel of the viewer as well.
You can also log arbitrary data via the general .send_property() method.
Properties are logged as static data and will therefore show up in the timeline as well.
Also, the side-panel shows an overview of the properties when a recording is selected.

Our snippets now contain examples for recording properties in all SDKs:

• 🐍 Python (recording_properties.py)
• 🦀 Rust (recording_properties.rs)
• 🌊 C++ (recording_properties.cpp)

Experimental send_table API

We are also working on better support for tables and dataframes in Rerun, a feature that has been requested several times by our community. With this release, there is now an experimental API send_table that can be used to send arbitrary Arrow record batches via the Python SDK and from notebooks. For now, while we evolve this feature, this API is separate from the rest of our logging APIs. This tutorial shows how to use this APIs and also provides more details on the current implementation. In future releases, we plan to improve support for the table representation in the viewer to facility more advanced analysis tasks such as filtering, or showing summary statistics.

Please note that this is distinct from our current send_dataframe API and dataframe query view.

⚠️ Breaking changes

This release changes how the SDKs interact with the viewer, as Rerun now relies heavily on gRPC.
Additionally, we have changed our file format and data model to be much more flexible in the future.
These changes will improve our backwards-compatibility going forward, but this also means that this release introduces breaking changes to our .rrd format and how the SDKs communicate with the viewer.

• .rrd files from previous releases cannot be loaded anymore
• Removed unsupported connection methods from the SDKs
• The connection URLs have changed and now require a rerun:// (TLS) or rerun+http:// (unencrypted) prefix
• Several changes to our logging SDKs (timelines, time units, …)

A small release addressing bugs and polishing rough edges.

🛠️ Note on 0.20.0 release

An issue with the 0.20.0 release led to incorrect artifacts being published, causing a few minor changes to be missing from those artifacts. The correct version has always been available on crates.io, PyPI, Conda, and other distribution channels, so no action is needed if you installed from these sources.

🤖 Native loading for LeRobot datasets

We're gradually rolling out support for native loading of LeRobot datasets. It’s not fully feature-complete yet, there are tons of variations in these datasets, so it’ll take a bit of time to cover all the edge cases. More improvements and features are planned for the 0.23 release, so expect things to get smoother and more robust soon.

If you run into any issues, let us know! Your feedback helps us iron out bugs and improve the experience faster.
