 - **2026-10-21 (M3, #3808):** Page thumbnails in the Inspector can be resized independently from the document and Organize, with a slider, buttons and `thumbnail-zoom` control option. Selection, page following and reload are covered by regressions. Estimates unchanged.
 - **2026-10-22 (M2, #3107 / PR #3438):** Inline-image parsing falls back to the existing EI heuristic when missing declared samples, headers or terminators exceed the content-window budget, instead of waiting for an impossible allocation. Exact-length parsing for available samples and ordinary large streamed images is retained. Estimates unchanged.
 - **2026-10-21 (M14, Brazilian Portuguese):** Completed the `pt-br` catalog against the current 2,674-key union, including signature validation and accessibility messages; no build or compilation run. Localization remains partial because help and unpredictable engine/OS error details are not translated.
+- **2026-10-19 (M11, #2178):** Optimize checks image and soft-mask dimensions and byte counts before decoding; hostile-dimension regressions pass. Estimates unchanged.
+
+- **2026-10-20 (M11, #3507):** Image merging keeps trailing comments, split operands and graphics state across content streams. Synthetic tool tests check saved text, rendered regions and exact image rows.
+
+- **2026-10-17 (M8, gap 6, #2662):** A filled cover over a long line counts when it hides half of any one word, not only 40% of the line's words or box, so a black box over one number in a long line — or an unapplied redaction mark over it — no longer audits clean while the number is still extractable; a sliver under half of every word it touches and under 40% of the line is still not flagged
+- **2026-10-13 (M10, #1757):** Office export keeps each dotted-leader contents entry in one paragraph, with its page number, instead of inferring table cells from its separate text objects.
 - **2026-10-20 (M6, calculation order page):** Prepare a form ▸ Calculation order, a page of its own, lists the calculated fields in the order they calculate with their formulas and values, moved with Up/Down arrows (as Acrobat's Set Field Calculation Order), Alt+↑/↓ or by dragging. A card says what is wrong with the order and holds Fix order; a loop has a card of its own that opens one of its formulas. On the page, each calculated field shows its step, and arrows show what the field in focus reads and what reads it. Estimates unchanged.
 - **2026-10-20 (M6, calculation order):** The order a form's fields calculate in (`/CO`) is read, checked, fixed and set headlessly with `form_calculation_order`: it says which fields read one calculated later (they show stale values), which read each other in a loop, and which the PDF's order leaves out; Fix order moves only what must move, in one undo step, and the form recalculates. Editing a formula no longer moves its field to the end of the order, and a field the order lists twice calculates once. Estimates unchanged.
 - **2026-10-20 (M2, #3574):** Forms without Resources use page Properties for ActualText and layer visibility. Synthetic tests cover boundaries, nested/shared forms, and save/reopen. Estimates unchanged.

 - **2026-10-19 (M4, #3309 review):** Page deletion keeps working with 60,000 named destinations, without a name-count traversal limit. Synthetic regressions verify every surviving target after deletion and restoration of the deleted page and its destinations by undo/redo, full/incremental save/reopen and unchanged rendering. Estimates unchanged.
 - **2026-10-18 (M4, #3309):** Deleting a page prunes named destinations without recursive calls. Cyclic and shared indirect nodes are visited once. Synthetic deep/cyclic graph, save/reopen and automation regressions cover the change. Estimates unchanged.
+- **2026-10-18 (M1, #2658):** macOS atomic saves retain destination extended attributes, including Finder tags, and reject partial resource-fork reads after size changes. Metadata failures retain the original PDF and unsaved edit. Estimates unchanged.
 - **2026-10-15 (M7, Edit text caret):** In a text region that mixes sizes (a 24 pt title over 12 pt lines), the inline editor's caret on a small row was as tall as the region's first size and reached into the row below: egui draws the caret at least one row of the text field's font tall, and that font had the paragraph's first size. The field's font is now half the region's smallest size, so each row's own height decides. Kittest regression; checked in the app on a real document. Estimates unchanged.
 - **2026-10-16 (M3, #2781):** The Pages panel follows the current page, as Acrobat's page thumbnails do: going to a page whose thumbnail is out of sight (scrolling, Page Down, Go to page, a bookmark) scrolls the panel just enough to show it. A thumbnail already in view, or clicked, leaves the panel where it is, and a page change while the user scrolls the panel or drags thumbnails does not move it. Estimates unchanged.
 - **2026-10-16 (M12, #1645):** CLI info, text and render use the engine's dynamic XFA layout rather than placeholder pages. Synthetic two-page and encrypted-form regressions cover counts, text, pixels, copy permissions and unchanged input bytes. Estimates unchanged.

 - **2026-10-15 (M14, gap 24):** `misc.localization` and `misc.installers` move from planned to partial. Localization: 22 catalogs ship, but Chinese shows tofu in releases, Telugu has no release font and Arabic is not mirrored. Installers: macOS and Windows releases are signed, Linux packages are not. The Acrobat menu diff itself remains open. Estimates unchanged.
 - **2026-10-15 (M14, PNG export):** Export ▸ Image as PNG, `pdfcraft-cli render` and the `page_render` automation/MCP tool write an opaque page as RGB at deflate level 3 instead of RGBA at the default level 6: the files stay the same size and are written 3–5× faster (a 300-dpi scan drawn at 220 dpi: 805 → 167 ms; a text page at 220 dpi: 70 → 40 ms; an annual-report page at 150 dpi: 179 → 64 ms). A page with translucent pixels is still written as RGBA. The automation tools use the engine's encoder instead of a copy of it. Estimates unchanged.
 - **2026-10-15 (G14, Romanian localization):** Added Romanian (`ro`, Română) as an interface and date language with a 2,673-entry catalog covering every bundled key, and a CLDR plural rule (`plural_ro`: one / few / other, "20 de pagini"). Locale tags `ro` / `ro-RO` / `ro_RO.UTF-8` / `ro-MD` resolve, so Auto picks it on Romanian Windows. Coverage and plural tests added. Status `partial` like the other catalogs (no translated help).
+- **2026-10-22 (M14, JPEG and TIFF export):** Export ▸ Image as JPEG or TIFF refuses a raster that is not exactly width × height pixels, as PNG export has since #2425. A raster a pixel short panicked inside the JPEG and TIFF encoders, and a partial pixel at the end was dropped and the rest written as a valid image. Rendered pages are always the right size, so what exports is unchanged. Estimates unchanged.
 - **2026-10-13 (G14, Vietnamese localization):** Added Vietnamese (`vi`, Tiếng Việt) as an interface and date language with a 2,591-entry catalog (`plural_none`) covering 100% of the current localizable key union (plus `theme`/`Appearance`). Locale tags `vi` / `vi-VN` / `vi_VN.UTF-8` resolve; calendar months use numeric `Tháng 1`…`12` / `tháng 1`…`12`. Native-speaker community review recorded. The twelve-language localization mean moves from ≈59% to ≈68%; weighted readiness ≈49% → ≈50%. Status stays `partial`: engine/OS details, document contents, filenames, CLI/MCP and external help stay outside the catalog by design.
 
 - **2026-10-13 (M3, typed zoom):** The right rail's zoom percentage is an editable field: type 150, 150% or 62.5 % and press Enter, Escape discards, and nonsense keeps the current zoom. The control channel's zoom option shares its parser, which now refuses zero, negative and non-finite values.
