 ## Revision history
 
 | date | change |
 |:--|:--|
+| 2026-10-14 | Create: Strokes: a line whose ink is cut square at its ends gets square caps, and a wide line whose skeleton hooks towards a corner of its end ends on the line it was following (Outline: largest distance 2.94 px to 0.88; aliased lines 0.88 to 0.81) |
 | 2026-10-13 | Shapes: corners that anti-aliasing or blur took a little off are corners, a rounded rectangle gets the radius that fits, a polygon its sides from the outline itself, hard-edged outlines a little more room (plain shapes found: 57 to 62% up to 98 to 100%); a "false shapes" column |
