There's a new Steam Beta client available. To access the Beta, go to File -> Settings. On the Account tab press the Change... button to open the Beta Participation dialog. Then Select Beta Update, and allow Steam to restart itself. Here are the specific changes:
6/24/2010
- Added UI to disable Steam Cloud per-game and per-account.
- Added an icon in list view for uninstalled games that support cloud.
- Steam Cloud will now download files for installed games on logon.
- Fixed Steam Cloud sync failures that occurred because of deleted files.
- Improve text hit testing in chat windows.
- Make player names in chat windows clickable, taking you to that user’s profile.
- Fixed tabs in the settings dialog sometimes not drawing correctly.
- Fixed a regression that prevented steam from automatically validating and repairing damaged game caches on launch.
- Shortened the delay between launching steam and being offered offline mode in the case of no network connectivity.
- OSX: fixed a class of bugs that could cause steam to hang while shutting down, especially if network settings had changed.
