I have just updated the plugin to version 1.5.3. The changes in this version are:
- Change: Cleanup in preparation for calibre 6/Qt6.
- Fix: Use mobi-asin identifier
The latter was released as a beta some time ago and I had completely forgotten about it.
While this is being updated in preparation for calibre 6 and Qt6, this should still be backwardly compatible with older versions of calibre. But, I am no test with anything older than version 3.48.
The plugin should be announce by calibre in the next hour or so. If there are any problems, please report them here.
