Steam can now serve 64bit games on Linux!

Finally the Steam Beta from the 18th has added support for launching 64bit titles! I am sure this will be of interest to quite a few of you 64bit users who don't want 32bit clogging up your systems!

Fixes and additions in the 18th June Beta

• Added support for 64-bit Linux titles
• Added a "friendly machine name" when Steam-Guarding an account
• Changed data format of client updates to improve compatibility with flawed proxy servers.
• During login, if Steam can't be reached and the user has entered a username we've never seen before, pop a dialog and ask them to login again
• When returning to the login dialog and we've cleared the username field, put the keyboard focus on the empty username box instead of the password box
• Fixed failing to update a game properly if an unexpected folder exists in the install directory for a game and we want to replace it with a
  new file
• Fixed finding Steam client skins on Linux
• Fixed crash looking at community images on Linux
• Fixed Linux Steam overlay not restoring the proper mouse cursor in certain situations

Big Picture

• Fixed focus issue with the startup UI when the intro movie terminates early
• The play button on a games library page is now disabled if the game is not available on your platform
• Fixed updating background images in the library details view even when not visible while a game is running
• Fixed regression in prior update that made the Web/Friends footer buttons not appear in the in-game overlay on startup

Will be great when this gets into the public client (I personally don't use the Beta client to stay a little more stable).
