Inspired by DoubleAA. Is there a special text one should say on finishing a Masechta in Yerushalmi?
Most notably by saying
הדרן על מסכת ברכות מתלמוד ירושלמי
As demonstrated at this siyum (recording #31).
There didn’t seem to be any other changes.
DoubleAA’s comment was a simple pun demonstrating that when it would be a Siyum HaShas for Yerushalmi, one would say
הדרן עלך תלמוד ירושלמי
As is evident on the last recording linked above.
