Alpha 9 Release Note !
Published on December 1, 2025 by Romain Guimbal
Once again about everything changed. hundreds of node groups improved and added, NURBS are more accurate and functional, the importer is close to reliable, everything is closer to the STEP standard, compounds, and several solvers have been implemented so intersections and projections are now good ! (in their still limited supported cases)
