Editing Psi (instant messaging client) (section)

== History ==
The application was created by Justin Karneges and it began as a side project. At various points during its existence Karneges was paid to develop the codebase, during which Psi flourished. Typically however, the release cycle of Psi is relatively slow, but the client has always been seen by its fans as a very stable and powerful instant messaging client. Karneges left the project in late 2004 to pursue other endeavors.<ref>{{cite mailing list |url=http://lists.affinix.com/pipermail/psi-devel-affinix.com/2004-November/001280.html |title=&#91;Psi-devel&#93; Passing the torch |first=Justin |last=Karneges |date=November 25, 2004 |mailing-list=psi-devel |access-date=January 24, 2012 }}</ref>
In 2002 Michail Pishchagin started hacking Qt code which later became libpsi library. Pishchagin joined the team in March 2003 and he is responsible for many large chunks in Psi code.

In November 2004, maintenance was taken over by Kevin Smith, a long-time contributor to the project. In 2009, Smith handed maintenance back to Karneges,<ref>{{cite mailing list |url=http://lists.affinix.com/pipermail/psi-devel-affinix.com/2009-March/008511.html |title=&#91;Psi-devel&#93; Psi - under new^h^h^hold management |first=Kevin |last=Smith |date=March 5, 2009 |mailing-list=psi-devel |access-date=January 24, 2012 }}</ref> who also maintains Iris, the [[Qt (framework)|Qt]]/[[C++]] XMPP library upon which Psi is based.<ref>{{cite web |url=http://delta.affinix.com/iris/ |title=Iris XMPP Library |work=Delta XMPP Project |publisher=Affinix Software |date=December 5, 2004 |access-date=January 24, 2012 |archive-url=https://web.archive.org/web/20060211051839/http://delta.affinix.com/iris/ |archive-date=February 11, 2006 |url-status=dead }}</ref>

Remko Tronçon started writing his custom patches for Psi in 2003, and became an official developer in May 2005.

In 2009 a Psi [[Fork (software development)|fork]] named [https://psi-plus.com Psi+] was started. Project purposes are: implementation of new features, writing of [[Patch (computing)|patches]] and plugins for transferring them to [[Upstream_(software_development)|upstream]]. As of 2017 all active Psi+ developers have become official Psi developers,<ref>{{cite web |url=https://github.com/psi-im/psi/blob/a7afbd9a0d/README.md#development |title=README.md |website=[[GitHub]] |date=March 7, 2018 |access-date=March 7, 2018 }}</ref> and now Psi+ is just a development branch of Psi with [[rolling release]] development model.

Users who wants to receive new features and bug fixes very quickly may use Psi+ on daily basis. Users who do not care about new trends and prefer constancy may choose Psi as it uses classical development model and its releases are quite rare.
