+| 2026-10-30 | minor | Raster images: the picture is loaded from its file when a drawing opens and drawn on screen and in PNG output (#1756, viewport part; based on #1029) |
 | 2026-10-29 | minor | R2000 DXF: CLASS records written without group 91 (instance count), which came with the 2004 format; AutoCAD LT 2026 stopped responding on every R2000 DXF CADCraft saved (checked black-box in AutoCAD LT 2026) |
 | 2026-10-26 | minor | CC-046: ATTEDIT and -ATTEDIT value changes invalidate derived justified baselines before DXF/DWG export; preserve alignment anchors, unchanged values and Aligned/Fit endpoints. Review follow-up: baseline recomputation preserves insertion elevation independently of alignment elevation. The shared writer correction also applies to justified TEXT. Independent of attribute editor UI; reverting the follow-up restores elevation loss on recomputation, while reverting the value setter restores stale XY baselines. |
 | 2026-10-25 | minor | LAYOUT SAveas (`layout.saveas`) writes a layout as a drawing template: its page setup and paper space objects, no model space objects or other layouts, and only the named objects they use |
