Hi, some days ago jrtc27 helped me on the IRC to figure that a upload of debian-edu to unstable has prevented the transition of thunderbird packages to testing. The reason was probably that education-lang-zh-tw-desktop was depending on now non existing package iceowl-l10n-zh-tw in testing [1].
Now the fixed version of debian-edu has migrated to testing but thunderbird is still not migrating. https://release.debian.org/britney/excuses.yaml isn't showing any excuses (at least to me) why thunderbird isn't moving to testing. As all other releases have now already the latest Thunderbird version and 52.5.0 was also fixing some security issue as usual it would be good if testing would have the same version. Do I miss something why Thunderbird 52.5.0-1 isn't migrating? [1] https://bugs.debian.org/884193 -- Regards Carsten Schoenert
