Editing Plone (software) (section)

== History ==
The Plone project began in 1999 by Alexander Limi, Alan Runyan, and Vidar Andersen. It was made as a [[usability]] layer on top of the [[Zope]] Content Management Framework. The first version was released in 2001. The project quickly grew into a community, receiving plenty of new [[Plug-in (computing)|add-on products]] from its users. The increase in community led to the creation of the annual Plone conference in 2003, which is still running today. In addition, "sprints" are held, where groups of developers meet to work on Plone, ranging from a couple of days to a week. In March 2004, Plone 2.0 was released. This release brought more customizable features to Plone, and enhanced the add-on functions. In May 2004, the Plone Foundation was created for the development, marketing, and protection of Plone. The Foundation has ownership rights over the Plone codebase, trademarks, and domain names. Even though the foundation was set up to protect ownership rights, Plone remains [[Open-source software|open source]].<ref>{{cite web|url=http://plone.org/foundation/about/faq |title=Plone Foundation FAQs — Plone CMS: Open Source Content Management |publisher=Plone.org |date=2009-01-03 |access-date=2012-10-18}}</ref>
On March 12, 2007, Plone 3 was released. This new release brought inline editing, an upgraded visual editor, and strengthened security, among many other enhancements.<ref>{{cite web |url=http://plone.org/news/plone-3.0-released/ |title=Plone 3.0 released! — Plone CMS: Open Source Content Management |publisher=Plone.org |date=2007-08-21 |access-date=2012-10-18 |url-status=dead |archive-url=https://web.archive.org/web/20120309141041/http://plone.org/news/plone-3.0-released |archive-date=2012-03-09}}</ref> Plone 4 was released in September 2010.<ref>{{cite web |url=http://plone.org/news/plone-4-released |title=Plone 4 CMS Unveiled: Advancing Power, Performance & User Experience — Plone CMS:- Open Source Content Management |publisher=Plone.org |access-date=2012-10-18 |url-status=dead |archive-url=https://web.archive.org/web/20120309135231/http://plone.org/news/plone-4-released |archive-date=2012-03-09}}</ref> Plone won two [[Packt]] Open Source CMS Awards.<ref>{{cite web |url=http://www.packtpub.com/open-source-cms-award-previous-winners |title=Open Source Awards Previous Winners &#124; Packt Publishing |publisher=Packtpub.com |access-date=2012-10-18 |archive-url=https://web.archive.org/web/20090707094004/http://www.packtpub.com/open-source-cms-award-previous-winners |archive-date=2009-07-07 |url-status=dead}}</ref>
