Hello,

$SUBJ is coming to F38 (and later F37 and 36- well tested).

Here's the bodhi update: 
https://bodhi.fedoraproject.org/updates/FEDORA-2022-cba07364fb (will be merged momentarily).

Here's the test log:

Let me know if you have any questions or issues (I have not tested rebuilds of other packages yet).

Regards,
Pavel
