+### Fixed
+- **The language picker forgot which language was picked.** Android hands the
+  applied language back with its script filled in — Simplified Chinese goes in
+  as `zh-CN` and comes out as `zh-Hans-CN` — so after a restart no entry in
+  Settings → Language showed as selected, and the row above it named the
+  language the long way round. Only languages that imply a script were
+  affected.
