I have just updated the plugin to version 1.10.0. This update should fix some issues that were reported by some users and also contains other changes.
The updates are:
- Fix: Site change for release date, publisher, ratings and language - mentioned by @josephyw here
- Change: Fetch metadata directly if book has only ISBN identifier - mentioned by @gguigui here
- Update: Fall-back method to get series and genre info
Please post here if you find any problems with the update. If there's no issues, hopefully, some mod can help update the first post!
