+- 更新後、開いていた onw ウィンドウも新しい版で開き直すように（これまではページだけ読み直していたため、タイトルの版表示や

 - 画面を英語・中国語（簡体字）にも対応。OS の言語に合わせて自動で選び、「設定」の「言語」で切り替えられます

 Dates are JST. Every version is on Hugging Face `ryugyosoft/onw`, tagged from `v0.4.2` on.
 
+## v0.8.5 (2026-09-27)
+- After an update an open onw window reopens on the new version too (it used to reload only the page, so its title and
+  icon stayed old), on the same tab. The tray restarted by an update opens a window on the new version as well.
+
 ## v0.8.4 (2026-09-27)
 - The UI speaks English and Simplified Chinese too: it follows the OS language, Settings → Language switches it
   (onw window, tray menu and notifications, chat page, check page).
