### ✨ Overview & highlights

#### Python chunk processing API

This release introduces a chunk processing API designed for systematic and efficient wrangling of robotics data.
It includes:
- A `Chunk` object for inspecting, creating, and manipulating chunks.
- Readers for common file formats (RRD, MCAP, Parquet, URDF, and more to come) which output streams of chunks.
- A composable `LazyChunkStream` class to define memory-bounded chunk-based filtering and transformation pipelines.
- Lenses: an expressive and performant API to manipulate component data in chunks.
- A multithreaded, GIL-free, native engine for pipeline execution that is designed for distributed execution in the future.
- Interoperability with a catalog server and the Rerun SDK logging API.

In addition to enabling powerful data wrangling pipelines, the chunk processing API is significant for offering read/write chunk-level control of RRD files down to the raw Arrow data.

_Note_: this API is experimental and subject to breaking changes as we continue to improve it.

#### Experimental dataset review
You can now build tables of recording previews configured with arbitrary blueprints!

<!-- https://static.rerun.io/59636c2a3c79f0f4f543e353a87315ec416bdad8_datasetpreview%20new.mp4 -->

https://github.com/user-attachments/assets/7acf9671-c46a-4355-a50f-2670cc80c4d9

Clickable flags let you curate data directly from the table: toggles update a boolean flag column and are written back to the server.

To try it out, enable the experimental options in the Viewer's settings and try the two Python examples:
[`table_grid_with_flags`](./examples/python/table_grid_with_flags/) for basic grids with clickable flags,
and [`table_blueprints`](./examples/python/table_blueprints/) for the full preview experience.

Limitations, or why this is still experimental:
* previews don't yet work directly on raw datasets; you have to send a special table to the server instead (see examples)
* table blueprints are currently text-encoded in table metadata, this is subject to change
* depending on the number and content of previews, overall runtime performance can be poor, especially in the browser
* many UX details are still unfinished

#### Experimental state timeline view

A new experimental view for visualizing discrete state transitions over time as horizontal colored lanes, useful for state machines, mode transitions, and similar discrete signals. Log state changes with the new `StateChange` archetype; configure their display on the UI or using `StateConfiguration` in the blueprint API.

Read [our guide](https://rerun.io/docs/howto/visualization/state-timeline) to get started. Feedback is appreciated!

#### `GridMap` archetype and MCAP support for ROS occupancy grids

Rerun now supports 2D grid maps, as used e.g. in robot mapping & navigation applications, through a new `GridMap` archetype.

* A `GridMap` is an image buffer with defined cell size per pixel, which can be embedded as a textured rectangle in a 3D scene.
* `GridMap` has a regular `ImageBuffer` component, so you can also send color images (e.g. to do custom color-mapping in your code).
* For layering of multiple maps you can optionally set draw order and opacity when logging, or separately in the viewer / blueprint.
* The visualizer also supports the colormap options that RViz users are familiar with, selectable at log time or in the viewer / blueprint.
* In a 3D scene, the map appears at the entity's coordinate frame (either entity-path based or with TF-style named frame like `CoordinateFrame("map")`). Additionally, an optional translation & rotation offset can be specified.

For ROS 2 users:
* 🧢 Rerun's MCAP importer automatically loads ROS 2 `nav_msgs/OccupancyGrid` messages as `GridMap`s.
* 📖 Our [ROS 2 guide](https://rerun.io/docs/howto/integrations/ros2-nav-turtlebot) also shows an example how you can log `GridMap` from your custom ROS nodes.

Here's a demo video showing a typical ROS 2 MCAP recording with multiple map and costmap layers in Rerun:

#### OSS catalog server now streams from disk

The OSS server (`rerun server` and `rr.server.Server`) no longer eagerly loads RRDs in memory when registering datasets.
It instead uses the manifest embedded in the RRDs to load chunks on demand when serving requests.
This greatly extends the amount of data that can be registered and queried for a given memory budget, and makes registration orders of magnitude faster.

_Note_: This requires the RRDs to have a manifest, which most modern RRDs have.
Legacy RRDs are still eagerly loaded.
Use the `rerun rrd optimize` CLI to migrate and optimize legacy RRDs.

#### Plot improvements

</picture>

- Performance improvement for scenes with many series. Moved from egui CPU tesselation to GPU line rendering.
- Redesigned tooltips. Hovering over a plot now shows a cleaner, more compact tooltip with color swatches matching each series. Also it is visually obvious now when events were actually logged.
- Better NaN & Infinity handling. Time series views now gracefully handle non-finite values: the Y-axis range ignores them, isolated data points surrounded by NaN are drawn as dots instead of disappearing, and aggregation skips over non-finite values rather than corrupting nearby points


#### Performance improvements

This release comes with a few significant performance improvements. Among other things:

* Visualizing scenes with many transforms on the same entity (as it is often the case with `tf`-style named transforms) will now perform vastly better
* Plot line tessellation is now GPU accelerated, using the same rendering path as our 3D lines
* Web viewer now decodes images using the web decoder, resulting in much smoother play of raw-image "videos"
* various improvements to `rrd optimize` (former `rrd compact`) to produce more streaming & object storage friendly data
* MCAP decoder is now multithreaded

#### New branding

### ☁️ Highlights for Rerun Hub customers

Several improvements in the open-source Rerun SDK are designed specifically to work with Rerun Hub.
 Here are the key updates that are especially relevant if you're a customer of Rerun Hub:

#### Direct fetch from object storage for commercial `Rerun Hub` customers

The SDK will now fetch chunk data directly from the object store that holds your recordings, without needing to proxy the data through the server.
This allows for better performance in highly parallel workloads, as well as lower latency when the client is located close to the data store.

The old proxy path is still supported, and can be opted into using the `RERUN_CHUNK_STRATEGY=grpc` environment variable.

#### Experimental training dataloader

You can now train PyTorch models directly against the Rerun OSS server, with no intermediate export step!

The new highly experimental `rerun.experimental.dataloader` module exposes Rerun recordings as iterable or map-style PyTorch datasets, streaming encoded images, scalars, and compressed video (`h264`/`h265`/`av1`) on the fly. Random access, multi-worker prefetching, and DDP support work out of the box.

Each field accepts an optional `window=(start_offset, end_offset)` parameter, an inclusive range relative to the current index. When set, the field yields the slice of values across that window instead of a single sample. For example, `window=(1, CHUNK_SIZE)` returns the next `CHUNK_SIZE` action values after every observation, making action-chunking policies a single query per batch.

See the new [LeRobot ACT training example](https://github.com/rerun-io/rerun/tree/main/examples/python/dataloader).

Expect breaking changes between releases while we iterate on the design. For large-scale training, Rerun Hub offers a higher-performance backend.

### ⚠️ Breaking changes

* "Data loaders" renamed to "importers" to avoid confusion with the widely-used ML/PyTorch "dataloader" concept
* Rust Lenses API has been restructured
* `rerun rrd compact` renamed to `rerun rrd optimize`, has profiles and new defaults
* `DatasetEntry.register` requires a sequence of URIs (Python)
* URDF importer now loads the static transforms of the model to the `/tf_static` entity by default
* MCAP metadata and statistics are now saved to `__mcap_metadata`
