### ✨ Overview & highlights


#### URDF loader improvements

In the previous 0.28 release, we overhauled Rerun's [built-in URDF loader](https://rerun.io/docs/howto/logging-and-ingestion/urdf) to work with TF-style transforms with `parent` and `child` frames.
Now, taking advantage of these entity-path-independent transforms, we simplified the hierarchy in which URDF assets are stored.
Collision and visual meshes are now below separate entity path roots, making it easy to toggle one or the other.
Additionally, the paths are now more compact to make it easier to scroll through them.

#### `UrdfTree` utility in Python

We added a [`UrdfTree` Python utility](https://rerun.io/docs/howto/logging-and-ingestion/urdf#urdf-utilities-python) that can be used to simplify operations with URDF models, e.g.:
* accessing links and joints
* computing transforms from joint states
* retrieving geometry entity paths for links

We also updated our [`animated_urdf.py` demo](https://github.com/rerun-io/rerun/tree/main/examples/python/animated_urdf) to use this utility, showing for example how you can dynamically change the color of a gripper link based on its angle.

#### Experimental screenshots from Python

There's now an experimental screenshot API which allows to take screenshots of the Viewer or individual views:
```py
# Connect to a local viewer.
viewer = ViewerClient()
# Screenshot the entire viewer.
viewer.save_screenshot("entire_viewer.jpg")
# Screenshot only the view we created earlier.
viewer.save_screenshot("my_view.png", view_id=view.id)
```
For a full snippet check [here](https://github.com/rerun-io/rerun/blob/0.29.0/docs/snippets/all/howto/screenshot.py).

⚠️ There's still a lot of [rough edges](https://github.com/rerun-io/rerun/issues/12482) and this API may change in the future.


#### Improved target frame selection UI

The target frame selection UI now shows matching suggestions, making it easier to select a frame name from the transforms in your data.

#### Updated ROS 2 example & documentation

We refreshed the documentation showing examples of how some ROS concepts and messages can be mapped to Rerun, together with an updated Python node example. The documentation page can be found [here](https://rerun.io/docs/howto/integrations/ros2-nav-turtlebot).

#### Improved memory panel

You can now get some insight on which parts of your recording use how much memory in the viewer using the improved memory panel:

### ⚠️ Breaking changes
- **Python**: New API for visualizer overrides - `VisualizerOverrides` removed, now pass visualizer objects directly (e.g., `rr.SeriesLines()`)
- **Python**: `Entry.update()` deprecated in favor of `Entry.set_name()`
- **Python**: `CatalogClient` and `Server` constructor parameters renamed (`addr` → `url`/`host`)
- **Python**: Removed deprecated `rerun.dataframe` module (use `rerun.server.Server` and `rerun.catalog` instead)
- **Python**: Removed deprecated `rerun.catalog` APIs from 0.28
- **Python**: Internal submodules moved to underscore-prefixed names (e.g., `rr.color_conversion` → `rr._color_conversion`)
- **CLI**: `rerun server --addr` renamed to `rerun server --host`
- **Blueprint**: Component overrides from `.rbl` files created in previous versions cannot be loaded in 0.29
- **Data Platform**: Datasets need re-registration to populate `name` and `start_time` in segment table
