I deleted all calendars from the GUI (had one local) and uninstalled 0.9rc1. When I (re-)installed 0.8 I got an error that a newer version of the add on had been used and to keep me from corrupting data I was prevented to enable 0.8. I tried deleting everything from the extension directory but that didn't help either. Reproducible: Always Steps to Reproduce: 1. Install 0.9rc1 + restart Thunderbird 2. Uninstall 0.9rc1 + restart Thunderbird 3. Install 0.8 + restart Thunderbird Actual Results: Can't enable 0.8 Expected Results: Enable 0.8 possibly with the need to reimport the calendar data
What means 'issues related to timezones'? Did you filed a bug for this? Downgrading the calendar database is not supported. The current behavior is as specified.
1. Eventually I managed to reinstall the 0.8 addon by deleting the storage.sdb file. However, it would be nice if this could be added as a feature for downgrade (at least beginning from 0.9). Give the user the option to delete the data in the new format but don't lock out the older addon version... (luckily I created a backup of my calendar before upgrading so I just wanted to downgrade to a clean calendar which I could import the old data back into). 2. timezone issue - I am not sure if this is a Lightning issue of a ScheduleWorld issue. I just noticed that after syncing all of my appointments moved by one hour and apparently kept on moving thereafter. I posted about this on the ScheduleWorld forum (not sure who is to blame...).
Resolving INVALID, but you can file an bug regarding an enhancement for downgrade for comment#2 (1.).
