If you are using mobile linux with T-mobile/a T-mobile MVNO, you may have noticed that sending MMSes stopped working recently.
I figured out the issue and released a new version of mmsd-tng to fix it:
https://gitlab.com/kop316/mmsd/-/tags/2.1.0
https://gitlab.com/kop316/mmsd/-/tags/1.13.0 .
1.x uses libsoup2 and 2.x uses libsoup3, there shouldn't be any differences between the versions besides that.
@rpm
It took me be surprise too. I only realized something was up when someone asked why I wasn't responding to their texts.
Thankfully the solution was not too difficult to figure out.
