Changes from v0.90 Build 13481 Beta -> v0.9.0.1 Build 13608 Beta

• We've just released µTorrent Mac 0.9.0.1 . You can download it from http://mac.utorrent.com/ or use "Check for Updates" menu to update from within the app if you have 0.9.0.
• This minor update works-around a problem in Mac OS that causes crash in Finder when double-clicking on ".torrent" file when uTorrent is the default application for .torrent files.
• This unfortunately required to change name of the file in which we store preferences so you might lose some of your preferences.
• µTorrent Mac is currently released as Intel only and only for 10.5 (Leopard).
• Preliminary support for PPC is in the binary, but it is unstable and not recommended for general use. PPC support will improve in the near future.
