Version 0.13.1

Prefab placements move with their group, the History tab shows what each step changed, and the timeline tools sit on one block of keys

• Dragging a group that holds prefab placements now moves what those placements place. Before, the copies stayed on their old frames, and a move of one frame to the left was enough to print the error Frame must be at least 1 on every frame for the rest of the session
• A trimmed placement keeps its own animation in place after you edit its span. Before, the edit slid the placement's keyframes against the content it places
• Every row of the History tab, and every undo or redo line in the console, now carries the numbers behind the step: the object's id and name, the track, and the frames it moved between (for example f150 -> f160)
• The timeline tools moved to one block of keys in the same order as the toolbar: Z folding, X snapping, C selection, V marquee, B scissors, N edges. Before, V was selection and C was scissors, so check your habits. A tab with fewer tools drops them from the right (the Local tab has Z X C V), so a letter never means a different tool on another tab. All six rebind in the settings, as Tool: Snapping, Tool: Cycle Folding and so on
• Validation no longer floods levels that use prefabs with false issues. On a level of 700 objects it reported 38 736 broken remaps and 19 993 dangling root overrides, and none of them were real
• The built-in level New zero demo is taken out of this version
