Bonsai v0.8.5 has been released with 962 new features and fixes. The release is described as a “line in the sand”: a compatibility and consolidation checkpoint driven partly by Blender 5.1 support, the move to Python 3.13, and a lot of structural work preparing for larger changes ahead.
Headline Bonsai improvements include the new BonsaiPR community build channel, a parametric gizmo system for editing doors, windows, stairs, railings and roofs, quick favourites, UI customisation, linked IFC project improvements, ifcgit workflow updates, better search, snap and polyline robustness, drawing fixes, MEP port improvements, bSDD V5 API support, and ifcsverchok additions.
IfcOpenShell also gains a larger command line and AI tooling layer: ifcquery for interrogating IFC models, ifcedit for scripting model changes, ifcopenshell-mcp for model querying and editing through MCP, and ifcchat for AI-assisted interaction with IFC files. Under the hood there are build system upgrades, Windows ARM64 support, Pyodide WASM wheels, critical bug fixes, API cleanups, geometry improvements, and IfcConvert enhancements.
