I have just release version 1.8.0 of this plugin. This is to fix the recent problems with calibre 3.24 and later. The changes in this version are:
- Fix: Version of BeautifulSoup was updated in calibre 3.24.0 and the plugins usage needed to change.
- Fix: Error when moving/updating annotations.
Calibre will announce the update in the next hour or so. And as usual, if anyone sees any problems, please report them here.
