Release notes

What changed in each WiTwin Studio beta release, newest first.

Studio is in beta. Beta builds are published as pre-releases on GitHub and installed copies update themselves.

Next beta #

These changes are on the development branch and ship in the next beta.

The Agent runs inside the Project's server process. A turn keeps going when you reload the window, and a Project runs one writing turn plus up to four read-only turns at once.
Subagents, background Sessions, plan mode and question cards.
Add to Chat puts an object, file, Result or text selection into the message as a context chip.
Automatic compaction of long Sessions and model-written Session titles.

No start screen: with no Project open, the chat shows six template cards (Empty Scene, Radar Sim, Channel Sim, EM Design, Home Simulation, Street Map). Plugins can add more.
The Projects list groups Sessions under each Project, marks the loaded Project, and confirms before switching.
Every new Project is an ordinary Python project with a git repository and a first commit. The witwin command and the witwin.studio package open, edit and solve it without the editor.

Parameters, formulas and units replace the node editor (Formula Graph).
Design Optimization with gradient, sweep, Monte Carlo, genetic, PSO and Bayesian Studies.
Viewport modeling toolbar, parameter handles and Edit Mode for points, edges and faces.

Git view in the top bar: stage, commit with model-written messages, branches, remotes, object-level Scene diffs and Git LFS.

Shadows redraw only when the Scene changes, and the Ultra preset no longer uses MSAA, which makes large Scenes faster.

Released 2026-07-17. The previous public beta.
