For years or decades even, CTAN announcements of any package update/changes is send to comp.text.tex all the time.
On Feb 17, 2022 they suddenly stopped.
If you go to https://groups.google.com/g/comp.text.tex, and then click on the second page, you will see the last post there on Feb 17. Here is direct link to the last one.
I use thunderbird and view comp.text.tex via nntp.aioe.org which is convenient.
Why did this happen? And will it resume again or is it permanent?
Update
I guess based on the answer below someone was forwarding all these announcements for years to comp.text.tex and now they stopped but nothing changed in CTAN to cause this?.
I do not know how they managed to do this since the headers of the posts all indicate they were ctan-ann@ctan.org? Any way, too bad to see these stop. Here is header of the last post so you see it looks like they were generated from CTAN directly.
