+- **2026-10-20** · A new document's Swatches panel lists InDesign's defaults: [None], [Registration], [Paper], [Black] and six process colours (C=100, M=100, Y=100, C=15 M=100 Y=100, C=75 M=5 Y=100, C=100 M=90 Y=10); the extra M=100 Y=100, C=100 Y=100 and C=100 M=100 swatches are gone. No readiness percentage change.
 - **2026-10-16** · Type › Reload Fonts (`font.reload`): fonts installed, edited or removed while DesignCraft runs are read again without a restart, and the open documents recompose with them (#328, #547). An edited font file is noticed by its length and modification time; bundled, added and document fonts stay as they are. InDesign does this by itself, so noticing changes automatically is still open (gap 6). No readiness percentage change.
 - **2026-10-16** · Parents can be deleted from their Pages-panel context menu or `layout.parents.delete {id}`. Applied-page and based-on references are cleared, local override copies survive, and Undo restores the parent. Addresses the deletion portion of #956; no readiness percentage change.
 - **2026-10-17** · File › Package writes the document's and the IDML's links relative to the package (`Links/logo.png`, `file:Links/logo.png`), so a package holds no path from the machine that made it; opening a document resolves them to the files beside it. Links › Copy Link(s) To still links by full path. (#340). No readiness percentage change.
