This is 2026.9 preview documentation. Coverage here is incremental: a page exists only where 2026.9 differs or is newly documented.
In 2026.9 the Grasshopper connector keeps existing scripts working. Nodes already on your canvas are renamed and hidden from the ribbon. They are not deleted, and no wires break. This page covers only what changed. For publish and load today, see How to use Speckle for Grasshopper. For the step-by-step script upgrade, see Upgrade Grasshopper to 2026.9.

​
What changed

  • Load and Publish in the ribbon are the current nodes. Nodes you already placed are renamed Load (legacy) and Publish (legacy). They still run. The same rename applies to (Sync) Load and (Sync) Publish.
  • Speckle Data Object is renamed Speckle Object. It is the same node with the same ports. Existing scripts keep working.
  • The current Speckle Geometry node has no Name or Properties inputs. Name and properties live on the Speckle Object that contains the geometry. Geometry nodes already on your canvas keep those inputs and are renamed Speckle Geometry (legacy).
Existing scripts keep working on the renamed nodes. You only need the current Load node if you want Explore, or if you are loading a version a teammate published with the current Publish node.

​
Publish

Versions from the current Publish node need an upgraded connector to read. Publish (legacy) can still be read by older connectors. Confirm collaborators have upgraded before you switch. The two nodes are independent of Load.

​
Load

The current Load node can return more objects than before, including property-only elements such as Revit rooms, levels, and areas. Materials and colours arrive on each object. The Proxies output is not on the current Load node. Model-wide properties such as project information arrive on a Properties output. The current Publish node has a matching optional Properties input. Name and properties live on the Speckle Object, not on geometry. A wall is one thing with one name and one set of properties, even when it has three meshes. To set a name or properties, wire geometry into a Speckle Object. Explore is a new node. After you load a 2026.9 version with the current Load node, it surfaces relationships such as level, room, host, and block definition. Plug in a Speckle Object, Speckle Geometry, Block Instance, or Collection. Explore creates an output for each relationship the model records for that object. The set of outputs changes with what you plug in. Explore does not repeat what the object already carries. Material, colour, and Collection path are already set on the object when it loads.
Explore supports versions published with 2026.9 onwards, loaded with the current Load node. Versions published before then do not record these connections, so there is nothing for Explore to show. Objects loaded with Load (legacy) also produce no Explore outputs. If Explore reports that nothing is cached for a model that loaded correctly earlier, reload the model.

FAQ

No. Nodes are matched by identity, not by name, so renaming them has no effect on your files. No node turns into a placeholder and no wire is dropped.
The usual cause is a version published before 2026.9, or a Load (legacy) node. Republish with the current Publish node, then load with the current Load node.
It does not. The node in your script is Speckle Geometry (legacy) and keeps all of its inputs. The Speckle Geometry in the ribbon is a new node without Name and Properties.
