Rogue Amoeba has released Airfoil 4.7.4, which now provides support for Airfoil Speakers for Android (which was recently released as a public beta). The network audio streaming app also improves support for audio sent from an Apple TV (running iOS 5.1 or later) to Airfoil Speakers and fixes a crash that occurred when selecting "Show Airfoil Only in the Menu Bar" in Preferences. ($25 new with a 15-percent discount for TidBITS members, free update, 9.1 MB, release notes)
Adding Links in Snow Leopard's Mail
Apple Mail in Snow Leopard now has a Command-key shortcut for adding a link to an email.
If you use plain-text email, this will not be helpful at all, but if you send styled email, it's a nice shortcut for adding URLs to your email messages. Simply select the word(s) you want to make into a link, press Command-K, and enter the URL to build into the link.
