It is NOT stated clearly in that post, at least not to someone for whom English is a second language! It is only stated that the renpy version is updated after the parts over (which I already knew from earlier versions!). Then the text goes on about that there is no offical end of the party at all, which says nothing else than it is very much in the eye of the beholder when the party is over!Still can't read apparently... The post right above yours CLEARLY states the the party event is NOT over yet. And is not being completed in the upcoming patch either.
So the guy making the port could decide that the new update is close enough to count as an end to the party and start his port. He could also decide to wait a bit longer.
Personally it is itching me to post something in my mothertongue for you to read! And seeing how well you understand every nuance of it!
