 - 2026-10-22: Effect › Sketch › Conté Crayon: a black crayon in the dark areas and a white one in the light areas, on mid-grey paper whose texture (Brick, Burlap, Canvas, Sandstone; Scaling, Relief, Light Direction, Invert) breaks the strokes, with Foreground Level and Background Level; an original approximation, defaults unverified. Every Photoshop-style filter is now in (57/57); the Effect Gallery remains (4–6 h).
 - 2026-10-22: Ruby (ふりがな) for live text: `type.ruby` sets or removes a reading over a byte range of the selected type — above it in horizontal type, right of the column in vertical type (or below/left), start/centre/end aligned, at 1–100% of the base size (default half), overhanging or squeezed to the base width. It is saved in the native file, laid out with its line growing (following lines move on), drawn on the canvas, and written in SVG and PDF as outlines where ruby is present. UI panel and type on a path are next. Headline numbers unchanged.
+- 2026-10-22: PDF accessibility: titled exports set `/ViewerPreferences << /DisplayDocTitle true >>`, so viewers show the document title rather than the file name and title checks can pass (#3646). Headline numbers unchanged.
 
 - 2026-10-14: Document fonts register every explicitly supplied craft-fonts family after the existing Japanese, Arabic and Thai prefix; optional empty input remains supported. Headline scores and estimates are unchanged.
