Should we hold back until someone gives the all clear here, that they haven't blocked PlexConnect?
An update was just announced:

Thanks, couldn't see this topic, hope its not a dupe
Edit:
It appears that today's forced channel updates have broken our use of the 'Trailer' channel.
It was not a firmware update.
It may be related to fixes being done to the Trailer channel to make it work with current beta firmwares.
I hope PlexConnect can be tweaked to adapt to changes like this

Latest Apple TV Update Breaks PlexConnect Client
Plex allows users to store movie and TV show files on a server and then view those files on a wide variety of client devices including Macs, PCs, a number of smart televisions, the Roku box and the Apple TV. The server also connects to Internet databases to pull IMDB-type metadata on media.

The client, called PlexConnect, used a hack to get video from the Plex Media Server onto the Apple TV. A small Python program on the Mac intercepted DNS requests from the Movie Trailers app on the Apple TV and instead returned a custom XML feed that delivered a list of media and movie streams to the device.
Now, however, Apple has closed the loophole. Previously, the Trailers app used regular HTTP requests and the PlexConnect app intercepted those requests. Now, the Trailers app uses HTTPS and it is likely impossible for the Plex programmers to overcome it.
Plex CTO Elan Feingold told MacRumors that the company was "saddened to hear that PlexConnect stopped working" and that "we can only hope that in the future Apple decides to release an SDK for the ATV". "The level of interest in the project was quite high."

The instructions, although somewhat technical, are fairly easy to follow. Users will require a copy of Apple Configurator (which is currently only available on OS X at the moment) and a micro-USB cable in order to connect their Apple TV to their Mac.
The fix is only intended to be temporary, and it may be disabled in future Apple TV updates. Yesterday, Plex Chief Technology Officer Elan Feingold told MacRumors that the company was "saddened to hear that PlexConnect stopped working" and that "we can only hope that in the future Apple decides to release an SDK for the ATV", citing that interest in the project was "high".
