The plugin has been updated to version 1.12.0. The changes in this version are:
- Fix: Errors when the series index was not just a number.
- Fix: Edit the rating in the Sync Progress dialog gives an error and the drop down appears in the wrong place.
- Fix: Use local timezone when displaying the date read.
The first an last have been in recent betas. The problem on the Sync Progress page was something I noticed and is related to recent changes in calibre.
The update should be announced by calibre soon. If there are any problems, please report them here.
