 - **2026-10-24 (M3, window move on Wayland, #3970 follow-up):** After a move or resize by PdfCraft's own title bar or edges, the button release given back to egui goes before the pointer leaving the window, so hover no longer sticks at the old place until the pointer moves. Found by CodeRabbit in review of #3970; a unit test covers it. Estimates unchanged.
 - **2026-10-24 (M14, #4253):** The annotation quick bar remembers Keep tool selected across restarts, including unpinning. Old and malformed settings keep safe defaults; the opt-in UI control channel reads and changes the same preference. Estimates unchanged.
 
-- **2026-10-24 (M11, black-and-white pictures):** A scan saved as a 1-bit PNG became an eight-bit grey image when made into a PDF, larger than the PNG; Create PDF now stores pictures of only black and white at one bit (Group 4 when smaller), the optimizer packs eight-bit black-and-white grey images to one bit, and Export ▸ Images reads CCITT fax images.
+- **2026-10-24 (M11, black-and-white pictures):** A scan saved as a 1-bit PNG became an eight-bit grey image when made into a PDF, larger than the PNG; Create PDF now stores pictures of only black and white at one bit (Group 4 when smaller), the optimizer packs eight-bit black-and-white grey images to one bit unless the grey settings make them smaller (a dithered scan), and Export ▸ Images reads CCITT fax images.
 - **2026-10-23 (M11, monochrome compression):** The PDF Optimizer and Reduce File Size store black-and-white images (scans, image masks) losslessly as CCITT Group 4 when that is smaller, with a Monochrome Images setting in the Optimizer and `doc_optimize` `mono`. JBIG2 and monochrome downsampling are next.
 - **2026-10-23 (M7, #4280):** Edit text names each standard stand-in font after its face (`PCEdTimesBold`, ...) instead of one shared `PCEdHelv`. Rewriting a bold paragraph whose subset lacks an accent no longer repoints the paragraphs set earlier in a regular stand-in at Times-Bold, and the editor's frame stays on the paragraph being edited. Pages saved by older builds keep their shared name and are not repaired. Estimates unchanged.
 - **2026-10-23 (M8, #3205 follow-up):** Phone-pattern redaction matches complete labelled Italian geographic numbers such as `Tel. +39 0426/123456`, with synthetic matcher and mark/apply/save/reopen coverage; unlabelled international slash numbers remain unsupported.

-| 2026-10-24 | minor | M11: Create PDF stores pictures of only black and white at one bit (Group 4 or Flate, whichever is smaller) instead of eight-bit grey; the optimizer packs eight-bit black-and-white grey images to one bit before Monochrome Images compresses them; Export ▸ Images decodes CCITT fax images.

 | 2026-10-23 | minor | M11: black-and-white images (1-bit, and image masks) are stored losslessly as CCITT Group 4 when that is smaller: PDF Optimizer ▸ Images ▸ Monochrome Images (on by default, so Reduce File Size too), `doc_optimize` `mono`; `pdfcraft_filters::encode_g4`. JBIG2 and monochrome downsampling not yet. Estimates unchanged. |
 | 2026-10-27 | minor | M10: OCR stages SHA-256-verified ONNX models after the upstream RTEN URL brownout; discovery prefers a complete ONNX pair per directory, falls back to a complete RTEN pair, and never mixes formats or directories; language/web limits and estimates unchanged. |
