+### v0.5.0
+- Atlas-Handle Bone-Draw: `render` zeichnet jeden Bone über den einzelnen
+  Atlas-Texture-Handle (`rig.atlas.diffuse_texture_handle`) plus per-Bone
+  UV-Rect (ADR-0044 Source-Rect-Args), statt eines per-Bone-Handles.
+- `load_textures` M.2-Rewrite: Per-Atlas-Texture-Handle; Bones referenzieren
+  Atlas-Index + UV-Rect statt der alten per-Bone Asset-Alias-Indirection.
+- `bone_world_transform(handle, bone_id)`: gibt die gecachte
+  Welt-Transform `x, y, rot` des Bones zurück.
+- Anchor-Hardcoding: Render liest `b.anchor[1]/[2]` (Default 0); fehlender
+  Bone-Anchor wird in `load_textures` auf die Tile-UV-Mitte gesetzt.

 ### v0.4.4

   of a currently-running animation WITHOUT resetting its cycle position.
