 - **A gallery of eight showcase labels** in the README (GS1-128 pallet, parcel, food, wine, lab specimen, asset tag, shelf tags with data merge, print conditions). Their `.rotula` files and the CSV data are in `docs/showcase`, and the pictures are rendered with Rotula's own PNG export by a test that only runs when `ROTULA_RENDER_SHOWCASE=1` is set.
 - **Text fit for wrapped text** (Properties panel, Text fit): choose what a text block does when its text is longer than the box. "Shrink to fit" uses the largest font size, between a smallest and a largest size you set, at which all the text fits; "Grow height" adds lines, up to a limit you set, so all the text shows. With data merge every record gets the size or the lines its own text needs, the canvas shows the same size that prints, and "Do not warn" hides the does-not-fit warning when cutting the text off is what you want. Labels that do not use it are saved exactly as before; a label that does cannot be opened by older versions of Rotula.
 - **Print an object only when you want it**: in the new Printing section of the properties, mark an object "Do not print this object" (a note or guide that never reaches the printer or an export), set "Print only when" a field equals, does not equal, contains, is empty or is not empty a value (so a warning can appear on some labels only), and "Lock position" so nothing moves it by accident. The Objects list and the canvas show small No print, Hidden and Locked badges.
+- **Portuguese (Brazil) and French (Canada)**: the whole interface is now also available in Brazilian Portuguese and Canadian French (View > Language, where each language is listed in its own name), and the installer offers both. On first run Rotula follows Windows: a Portuguese desktop gets Portuguese (Brazil), a French one French (Canada), Spanish stays Spanish and anything else English. Numbers and dates follow the chosen language. A language you picked before stays as it was. The "Language of Rotula" policy (Group Policy / Intune) also accepts `pt-BR` and `fr-CA`.
 
 ### Fixed
 - **Windows fonts that are named after a style now draw in that style.** "Arial Black", "Segoe UI Semibold", "Segoe UI Black", "Bahnschrift Condensed" and similar names used to be replaced by the default font in the preview, PNG/PDF export and print picture; they now resolve to their parent family at the weight and width the name says.

+- **Parity is tested**: every `Strings.*.resx` must have exactly the English keys, no empty value and the same `{n}`
+  placeholders per key, so a new language or a new key cannot ship half done.
