+## [1.3.4] - 2026-09-18
+
+### Fixed
+- **Automatic updates could not start on 1.3.3**: its installer was missing the updater
+  configuration file, because the packaging path used to guarantee the native module build
+  does not create it. The file is now written from the single feed source and its presence
+  in the packaged app is verified before publishing, so an installer that cannot update is
+  never shipped.
+
 ## [1.3.3] - 2026-09-18
