 | Date | Change | Summary |
 |---|---|---|
+| 2026-11-05 | patch | #2014: the panels drew a String variable's Amharic value as boxes: the UI took a system face for Hebrew and Arabic only. `bidi::script_fallbacks` now samples one letter of each of 16 scripts (Ethiopic, Devanagari, Gurmukhi, Gujarati, Tamil, Telugu, Kannada and Malayalam, Sinhala, Lao, Myanmar, Khmer, Armenian and Georgian as well as Hebrew and Arabic; Bengali and Thai keep `crate::cjk`'s faces) against the system's families for each (Windows, macOS, the common Linux fonts), the first installed one that draws the letter taken once. Desktop only: the web build has no system fonts. Test: `bidi::tests::other_scripts_take_an_installed_system_face` (skips scripts the machine has no face for). |
 | 2026-11-05 | minor | Documents: a paragraph's base direction can be forced left to right or right to left (Text ▸ Text direction, `text.direction`, `node.set textDirection`, the Type settings control, the `.fig` lines' `sourceDirectionality`), as Add right-to-left text says (#1830); detection stays the default. Four new UI strings (English only; other catalogs fall back). |
 | 2026-10-30 | minor | Bosnian (`bs`, Bosanski) draft catalog: every UI string (1,906), command label (629) and menu wording (31), machine-drafted in Latin script with ijekavian forms and marked as a draft awaiting native review. Bosnian plurals: one for 1, 21, 31… (not 11), few for 2–4, 22–24… (not 12–14), other for the rest. Grade and hours unchanged (Bosnian is not one of the twelve key languages) |
 | 2026-10-29 | minor | German terminology corrections (M10): gradient stops, OpenType stylistic sets and the Home-screen preference; partial review, catalog remains a draft. Nine existing translations corrected; keys, placeholders, coverage, grade and estimates unchanged |
