Comment 45 for bug 1895643

Although in this bug, marked 'fix committed' for focal a while now, I can't find the new thunderbird package in either focal-proposed nor focal-security . Also not shown on https://launchpad.net/ubuntu/focal/+queue .... Any ideas? -- be useful to see what package queues/links should be known about, and in any case, what happened to the committed fix.
With thanks!.
