@rerun-io/web-viewer - npm Package Versions

🛠️ 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.

0.19.0 - Dataframes & Video support

📖 Release blogpost: https://rerun.io/blog/dataframe

🧳 Migration guide: http://rerun.io/docs/reference/migration/migration-0-19

✨ Overview & highlights

This release introduces two powerful features: a dataframe API (and view), as well as video support.

☰ Dataframe API

We now have an API for querying the contents of an .rrd file. This integrates with popular packages such as Pandas, Polars, and DuckDB.

You can read more in the Dataframe API how-to guide.

We have also added a matching dataframe view inside the Rerun Viewer. Read more here.

🎬 Video

Rerun now supports logging MP4 videos using the new AssetVideo archetype. This can greatly reduce bandwidth and storage requirements.

While the web viewer supports a variety of codecs, the native viewer supports only the AV1 codec for the moment, but we plan to support H.264 in the near future as well. Read more about our video supports (and its limits) in our video docs.

⚠️ Breaking changes

• 🗾 Blueprint files (.rbl) from previous Rerun versions will no longer load automatically
• 🐧 Linux: Rerun now requires glibc 2.17+
• 🦀 Rust: The minimum supported Rust version is now 1.79
