PT is only available through Steam. You won't see the update for a while.
Here's how it works. I submitted the update to RSC today. The RSC folks don't go to work until Monday morning, GMT. First, they have to download the route from their server, along with all the other things they've got going on. Then they'll probably look it over, maybe change some things, and then send it along to Valve Corp. After a while it goes into the Steam queue and eventually you get the result. Can I put a time scale on that? No way!
I'm usually the last one to find out it's been updated! I still don't know if the Big Steam updates have happened at your level. Lucky me though, I have all the updates now
So now it's back to the next mystery project!
