known as Alchemy, have many major changes. Triggers are moving to a separate product, called Catalyst All the little frameworks are being joined into one big one called Crucible. This includes extensions and core functionality that most applications and plugins will use. This is currently called QSBase.framework The preferences will be greatly simplified. There will be Extras-style advanced preferences for the fiddly options. Plugins are going to be hidden from most users, they'll activate themselves automatically or be installable from the web β5X Plugins are incompatible. These builds have four major components: Crucible, a framework with extension to AppKit and tools common to all Alchemy applications; elements, a framework supporting the plugin architecture; quicksilver, a command window driven launcher; and catalyst, which triggers a preference pane. History Nicholas Jitkoff started development of Quicksilver in 2003. He released several versions to the public until 2006 and maintained an internet forum for the tool from the beginning. On October 30, 2007, the source code for Quicksilver was made available via Google Code. In November 2009, development shifted to using GitHub. Quicksilver is now developed by a team of volunteers known collectively as QSApp. At the end of 2010, the new website QSApp.com was launched, with the aim of unifying and collating all of Quicksilver's fragmented builds, plugins and support groups. Since its launch, the site has included a new Plugins Repository, Wiki and Downloads section. After several months of development, the milestone version β59 was released. On March 25, 2013, Quicksilver v1.0 was released after ten years of beta testing. On March 25, 2022, Quicksilver v2.0 was released, which runs natively on Apple Silicon (M1) Macs. Quicksilver's icon is based on the alchemical symbol for mercury, "quicksilver" being an archaic name for the element.
