 ## 0.6.27.4 (2026-09-04)
 - Fix: Kobo sync could not be enabled, failing with "Kepubify binary not found" even when the path was set by hand. The LinuxServer base image installs the converter as `/usr/bin/kepubify` with `curl -o`, which leaves it mode 0644 and gives it a name calibre-web does not accept : `binary_helper.py` only takes `kepubify-linux-64bit` or `kepubify-linux-32bit`, and only when `os.access(X_OK)` passes. The addon now makes the binary executable and publishes it as `/opt/kepubify/kepubify-linux-64bit`, the directory calibre-web's own autodetection already probes, so the path is filled in without any manual step (https://github.com/alexbelgium/hassio-addons/issues/3040)
 - Fix: on installs created before that change, calibre-web had already run its autodetection once, found nothing usable and stored an empty path, and it never retries. An empty path is now reset so calibre-web detects the converter itself at the next start. A path set by hand is left alone
+- Fix: `/usr/bin` also keeps working as a converter path, so the setting stored by anyone who applied the manual `ln -sf /usr/bin/kepubify /usr/bin/kepubify-linux-64bit` workaround keeps resolving after the update instead of silently breaking again
 
 ## 0.6.27.3 (2026-08-30)
 - Doc: explain in the README that Calibre-Web's optional extras (metadata, kobo, gdrive, gmail, goodreads, ldap, oauth, comics) are already installed by the LinuxServer base image, that `pip install calibreweb[...]` inside the container is useless and not persistent, and that the cover fields on the Edit Metadata page are gated on `Enable Uploads` plus the user's `Upload` permission (https://github.com/alexbelgium/hassio-addons/issues/1143)
