I don't do YT uploads, but you don't NEED to go directly from PrEl to YT, you could always create a suitable file out of PrEl and upload manually

Welcome to the forum.
As John T. points out, PrE was written when YouTube had restrictions of 10 min., and then they added Extended Subscriptions, and then lifted Duration limits.
The instructions in that thread, to which John T. linked, will tell you how to Share/Publish from PrE, to then manually upload via your YouTube/Google account. I would guess that with PrE 12 (probably due in Oct. 2013?), the direct PrE to YouTube uploading will reflect the YouTube specifications - unless YouTube changes the game, after it is written.
I doubt that there will be an update for PrE, just to reflect changes in YouTube, based on the history of the limited PrE updates. IIRC, PrE 3.0 got an update for Windows Vista, which was released, just after PrE 3.0 was, and the 2 updates for PrE 8, that fixed some pretty major Bugs. I do not recall any other PrE updates.

There is a Camera Raw 7.3 update somewhere for PrE11 that is not on that list. You don't need it unless you have a fairly new camera and want to put RAW photos in your video. You can collect it by picking a choice for updates on the help menu.
(It works well with a Sony RX100 mixing 1080p60 video and RAW photos without downrezing.)
Sharing/Publishing to a YT optimized file is more efficient than doing it from within PrE11 because you can't use PrE11 while the file is transferring to cyberspace. If you output a file with the built in presets under AVCHD, YT's uploader can work in the background while you continue to enjoy the use PrE11. Same for Vimeo.
Uploading from within PrE11 is a waste of time and resources regardless of the convenience.
