Version Control applies to the management of different versions of things be they documents, files, web pages, software releases etc.
Version Control in our sense is using a component for the Joomla! CMS which we have developed that allows you to work on and publish new versions of Joomla! articles (web pages), while preserving the historic copies.
This is an unprecedented feature and Version Control of articles in Joomla! is something we are thrilled to deliver.
What's more is there's an added bonus - you can also preview the articles in a full site template - complete with all stylings and modules.
