tangency-labs/solidcraft is a parametric 3D CAD application, and v0.29.0 was released on November 1, 2026. This version changes the save format to 46. The release notes state that files saved in the new format cannot be opened in earlier versions. It also includes a change that determines the interface display language according to the system language on first launch. The source is the v0.29.0 release on GitHub.
SolidCraft is an open-source parametric 3D CAD application built with Rust alone. The repository description presents it as supporting desktop and web, and also offering automation through MCP. So the publicly stated scope of use covers not just design on desktop or web but automation as well. The GitHub star count is 12634. Still, the number of stars alone cannot tell you the actual scope of use or the level of its design features.
The provided release notes contain neither the specific changes in save format 46 nor a way to move files from the old format. Because the new format cannot be opened in earlier versions, backward compatibility with earlier versions is limited. If you need to keep opening existing work in earlier versions, a conversion method may be required, but the information available here does not reveal whether such a procedure exists. The impact of the format change should be judged against this compatibility boundary.
