v0.2.6

Changed

• The update window now follows the Mac's language, so it appears in Japanese on a Japanese
  Mac. It was always in English before.
• Nonja is now shown in English unless the system language is Japanese.

Fixed

• Clicking a notification now jumps to it on macOS in any language, not only Japanese. Mark All
  as Read also clears the app in Notification Center on English macOS; in other languages it
  still marks it as read in Nonja only.
• The permission prompt for controlling System Events is now in English.
• Clicking a notification or clearing an app no longer freezes Nonja while Notification Center
  opens.
• When the notification database is missing, Nonja now names the path it checked, the verified
  macOS version, and where to report it.

Internal

• The build verifies the SHA-256 of the Sparkle archive it downloads.
• The release script runs the self test, and refuses a dirty working tree, a commit that is not
  on origin/main, an existing tag, a version the built app does not carry, or a missing
  changelog section.
• Releases stop instead of falling back to an ad-hoc signature when the signing certificate is
  missing.
