Sparrow has released version 1.4 of its eponymous email app. This update primarily involves performance and user-interface improvements, with everything from composing to synchronizing receiving a speed boost and some polish. Sparrow 1.4 also adds a few welcome new features, such as integration with the file sharing service CloudApp, pull-to-refresh, and support for proper first-to-last message sorting in conversation view. Several bug fixes round out the update. If Sparrow 1.4 prompts for your password at every launch, Sparrow suggests some possible workarounds until version 1.4.1 appears. ($9.99 new from the Mac App Store, free update, 12.0 MB, release notes)
