-### 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.
