We had an issue with a beta update of the Steam Client escaping into the wild last night, you may have noticed an update last night and a new one this morning reverting that change.
You can use the "File->Check For Steam Client Updates" to verify you have the most recent Steam build. If you wish to opt into Steam Client Beta updates then use the File->Settings dialog.
