 > **Floating anchor row segments:** 2026-11-07 · A floating anchor after a manual page/column break counts visible content on the far side of the same wrapped row. Marker-only cover anchors retain their previous-page rule. Synthetic picture spacing, placement and history controls; no new native Word measurement. Readiness estimates unchanged.

 | 2026-11-02 | trivial | For ODT documents, LibreOffice's layout: a line holding only in-line pictures is as tall as they are, without its font's ascent and descent (`Settings::odf_layout`, set when an ODT opens; Word keeps the font's, so other documents are unchanged).
