Apple TV 5.1 firmware adds multiple accounts, other changes

<Strong>(Updated with details of the security measures included with the firmware)</strong> Apple has released a major firmware update for second- and third-generation Apple TVs. The <a href="http://macnn.com/rd/268796==http://support.apple.com/kb/HT4448" rel='nofollow'>v5.1 upgrade</a> implements several new features, most notably the ability to save several iTunes accounts on the same unit and switch between them. App icons can now be reordered by holding down the select button, and new advanced network options can be set via configuration profiles. People with AirPlay-compatible speakers, AirPort Express routers, and/or other Apple TVs can use AirPlay to stream audio to them.<br><br>The firmware also allows viewing shared iCloud Photo Streams, and improves subtitle support, for instance enabling SDH for the deaf. New screensaver types include Cascade, Shrinking Tiles, and Sliding Panels.

Apple TV owners can download v5.1 through the General section under Settings.

<em>Update:</em> Security issues resolved with this update include the use of maliciously crafted graphics and movie files possibly leading to arbitrary code execution, connection to a malicious Wi-Fi network revealing previous networks the device has connected to, fixes to libxml, memory corruption issues in JavaScriptCore, and network privilege issues.

...multiple accounts / users for iOS6 (esp iPad 'guest') would also be helpful from my perspective...

"People with AirPlay-compatible speakers, AirPort Express routers, and/or other Apple TVs can use AirPlay to stream audio to them."

clear as mud.

Also, the big problem with subtitles on Apple TV is Netflix (they treat close captioning as subtitles), and this doesn't fix Netflix's app at all.

Anyone know if those 'advanced network features' include the ability to specify a web proxy?

keep on asking... maybe when iOS(X) has become a reality.

So the icons can be moved around now, except for the top row of Movies, TV, Music, Computers and Settings. This is good, I can move the baseball scores and WSJ out of the way at the bottom and move up Netflix and Youtube. Being able to move stuff around might be a sign of an Apple TV app store (I can hope), having TV catchup services and LoveFilm on there would be great. I've got the services on different things anyway, but not all in the same place and some aren't done that well.

It seems those advanced network settings are that you can specify a DNS server. I didn't see anything else.
