History

Sparkle 0.1 (beta) was released in January 2006 by Andy Matuschak to provide apps "instant self-update" functionality, which very few applications had at the time.[1]

In August 2009, Sparkle added support for delta updates for installing smaller and faster incremental updates. This was first used to update WebKit's nightly builds.[2]

In 2016, Radek discovered a man-in-the-middle attack vulnerability in applications that use Sparkle to receive updates through an unencrypted channel.[3]
