We've added two new logging primitives: GraphNodes and GraphEdges that can be used to visualize node-link diagrams. For this, we have implemented a new Graph View that uses force-based layouts to draw graphs.

This video demonstrates the main features of the new graph view:

UX improvements

This video demonstrates the main UX improvements that went into this release:

3D grid

The 3D view now offers an infinite 3D grid, enabled by default. Further controls and settings are available as usual through the blueprint API and/or the selection panel.

All the nitty gritty details in https://github.com/rerun-io/rerun/pull/8230 and https://github.com/rerun-io/rerun/pull/8234.

Undo/Redo support & many more UI/UX improvements

You can now undo/redo blueprint changes in the viewer! Watch @emilk putting it to action and explains how it works:

Other UX improvements

But that's not the only thing that improved in the viewer:

Breadcrumbs show up in the selection menu now
Take screenshots of views from context menus
Entities can now be dragged from Blueprint & Streams panel into views

Index of code snippets

We now have a new index for all our code snippets.

You can use it to quickly find copy-pastable snippets of code for any Rerun feature you're interested in (API, Archetypes, Components, etc). No special tools required -- all you need is a keyword of interest, and plain old text search.

It's still the early days so it is far from perfect, but we think it can already be quite helpful; feedback welcome. Most of it is auto-generated, so it will never get out of sync!

⚠️ Breaking changes

Near clip plane for Spatial2D views now defaults to 0.1 in 3D scene units.
Blueprint: types and fields got renamed from .*space_view.*/.*SpaceView.* to .*view.*/.*View.*.
3D transform arrow visualization show up less often by default.
DisconnectedSpace archetype/component is deprecated in favor of implicit invalid transforms (like zero scale or zero rotation matrix).
RotationAxisAngle with zero rotation axis is no longer treated as identity.
