Thank you DW-dev for making this add-on compatible with TB68.
The add-on that I want most of all to be compatible with TB68+ is your 'Calendar Tweaks' add-on.
You do amazing work! Thank you! It is greatly appreciated...
Calendar Tweaks 8.0 is compatible with Thunderbird 68 and Lightning 68. Calendar Tweaks 8.0 has been submitted to the Thunderbird team for review and should be released in a week or so.
