Compare 2026.8 and 2026.9

This is 2026.9 documentation. Coverage here is incremental: a page exists only where 2026.9 differs or is newly documented. For any other topic, switch to Current (2026.8 and earlier) in the version selector.

Use this page to see what 2026.9 changes for you, next to how Speckle works today. For the current product, switch to Current in the version selector. If you only publish and load through Speckle connectors, your day-to-day work stays the same. The rows below are the exceptions and dates that matter. For the full steps, see Speckle’s data model is changing.

What’s different

What you do	Before 2026.9	In 2026.9	Learn more
Publish, load, and view	You publish and load through connectors and the web app	You still do. After your project moves to the new data format, those flows are faster	What to do next
Models you already published	Your existing models stay readable	They stay readable. New publishes use the new format going forward	What to do next
ACC sync or drag-and-drop	Uploads use today’s data format	Uploads move to the new format. If another tool still needs the old format, ask Speckle to turn on compatibility mode as a short bridge. It ends for every workspace on 1 November 2026	Who should pay closer attention
Connector updates	Your current connectors keep working	Update them from 1 September 2026, and no later than 1 November 2026	What you should do now
Speckle Intelligence	It looks at properties on each object	It can also see how parts of a model relate to each other — what connects to what, and what contains what	What to do next
Data Validation	Checks, plus project standards on Enterprise	Project standards are not in 2026.9. Author checks. A later rollup from Checks to workspace standards is planned	Data Validation in 2026.9
Open a model in the web app	Current viewer: section box, Selection info, Filters	New viewer: hybrid load, docked Selection / Filters / Views, section planes	3D viewer in 2026.9
View point clouds	Point clouds render in the viewer	Not drawn in the new viewer yet. The data is unchanged and connectors that load it keep working. Support is planned for a later release	3D viewer in 2026.9
View colours and materials	Colours and materials from the source application render in the viewer	Some objects show as grey in the new viewer: Grasshopper colours, Civil 3D surface materials, and models published before the move to 2026.9. The data is unchanged. Publishing again fixes only the last case	3D viewer in 2026.9
Compare model versions	··· View changes on a version opens a dedicated diff view	Deprecated — no diff view in the Models ··· menu. Ask Speckle Intelligence (Chat, the viewer sparkle, or a Report) to detect, report, and assess the impact of what changed	Worked example
Navisworks models	Publish from the desktop connector	No 2026.9 desktop connector. 2026.8 is last, and still advised at 200 MB. Larger NWC/NWD: upload to 2 GB, ACC tested to 6 GB	Navisworks in 2026.9
Trimble Connect	Not available	New beta cloud sync on the Enterprise plan. Service account for background downloads; personal Trimble ID to browse	Sync models from Trimble Connect

This table is a summary. Follow the linked page for steps and dates.

Connector-specific changes live under Publishing & Loading: Revit in 2026.9, Grasshopper in 2026.9, Power BI in 2026.9, Navisworks in 2026.9, and Trimble Connect. Viewer chrome, Selection, Filters, and Views are on 3D viewer in 2026.9. Until a 2026.9 page exists for another topic, use the guides under Current in the version selector.

If you build on Speckle

If you use SDKs, APIs, Automate, or a self-hosted server, see Data model migration for developers. That page covers SDK updates, compatibility mode for uploads, and when to stay on 2026.8. Holding notes for the other developer tabs are under Developers in this preview.

FAQ

Why isn't my connector in the table?

Most people who publish and load through Speckle connectors keep the same workflow. 2026.9 details for Revit, Grasshopper, Power BI, Navisworks, and Trimble Connect are under Publishing & Loading. Other design tools still use the connector guides under Current in the version selector.

What if I cannot find a 2026.9 page for something I use?

Use the guides under Current in the version selector. If there is no 2026.9 page for that topic yet, the feature is still documented there. It did not go away.

Do I need compatibility mode if I only publish from desktop connectors?

No. Compatibility mode is only for ACC sync and drag-and-drop uploads when another tool still expects the old format. It ends on 1 November 2026. See Who should pay closer attention.
