Hi, as confirmed in another place at this thread one reason why TB115 is not in TW is because even upstream does not auto-update yet. The other is that using it myself I have the feeling it has a few edges. In any case I am/was a bit conservative with updating in TW but still providing packages for people who want to explicitely use it. And why Leap has TB 115 is mainly because TB in Leap is maintained by SUSE and therefore from another person. I was a bit surprised when I heard TB was so quickly updated in Leap and I don't know if there were certain reasons to do so. As of today Thunderbird 115.2.0 is already in preparation upstream and once this is released I plan to update in TW at the latest. I'm still hesitant to do it right now given that there is package available for the impatient. Wolfgang
