known as 'skeletons''. In early 2003, the 1.6 version made it possible to display the private back-end interface in several languages. A space for translators is set up in order to multiply the number of available versions. In January 2004, the 1.7 version of SPIP enables the management of multilingual websites, and implements a search and content indexing module; It also enables syndication of other sites' contents. In April 2005, the private interface of version 1.8 was reworked in order to take into account an analysis of ergonomic processes. An important modification for developers is SPIP's core that now benefits from a new compiler. It then becomes possible to elaborate skeletons with more complex functionalities without requiring any coding work in PHP. Other re-workings are currently under way, such as the reworking of the private interface in the form of skeletons. The 1.9 version (1) introduced a

system and numerous changes, notably in the organisation of component files (particularly the transition from '.php3' to '.php' files extensions. The 1.9.1 version introduced a template system, akin to Wikipedia. The 1.9.2 version modified the directory structure to allow a better mutualisation of sources. The 2.0 version supports multiple SQL databases, and introduces easy skeletons for web forms. The 2.1 version builds on the concept of modules, along with improved security and stability, a new interface for plugins management, and other features. The 3.0 major version was released on 19 May 2012:, completely redesigned towards a higher degree of modularity. All non-core functionalities are now implemented as plugins. The private area has been thoroughly rewritten in order to make the editorial objects as generic as possible. It's designed to be easier and quicker to create new editorial objects and to customize existing ones. The new DATA loop allows SPIP to connect to any kind of data (not only SQL tables).
