> Thunderbird version 60.0 is only offered as direct download from thunderbird.net and not as upgrade from Thunderbird version 52 or earlier. A future version 60.1 will provide updates from earlier versions. This means until 60.2.1, upgrades from older versions weren't fully supported by upstream. Only now it changed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1796126 Title: Thunderbird is out of date for two months when Thunderbird 60 was released Status in thunderbird package in Ubuntu: Confirmed Bug description: Thunderbird is one of the most used email clients.
