v0.1.2426 Sep 2026·Rendering

The layout engine is complete: columns that break like a magazine

This release finishes the from-scratch page-layout engine. Long content set in multiple columns now breaks the way a designer expects: a tall paragraph or a bordered card splits cleanly from the bottom of one column to the top of the next instead of overflowing, with its border and rounded corners sliced correctly across the break rather than repeated; a figure stays glued to its caption; a full-width heading spans across all the columns with a band of columns above and below it; and a column never strands a single lonely line at its top or bottom. Right-to-left text gets its finishing touches too: a paragraph set to auto-detect its direction now chooses left-to-right or right-to-left from its own first word, and brackets around Hebrew or Arabic curve and sit the correct way. Together with the vertical-writing and right-to-left work of recent releases, the engine now renders the full range of real-world page layouts as faithfully as a mainstream browser. Pages that use none of this are unchanged, to the pixel.

What changed 3 changes

Rendering	Content splits across columns properly. A paragraph, a nested section, or a card taller than one column now breaks at a line boundary and continues in the next column, and its background, border and rounded corners are sliced at the break (no border drawn along the cut, corners kept only on the outer edges) exactly as in the reference browser. A container mixing plain text and blocks now flows across columns instead of collapsing into one.
Rendering	Break controls and full-width headings work. You can force a heading to the top of the next column, keep a figure with its caption so they never separate, and a full-width heading now spans every column with balanced column-bands above and below it; the rule between columns breaks around it. Columns also honour the minimum-lines rules so no line is left stranded alone.
Rendering	Right-to-left finishing touches. Text set to auto-detect its direction now picks it from the first strong character, so a comment or field starting in Hebrew or Arabic lays out right-to-left on its own; and parentheses and brackets around right-to-left text now mirror and wrap it correctly instead of drifting to the wrong side.
