Subsequent major and minor releases (8.5.1 as of March 28, 2018) which bring numerous improvements and bug fixes (including CKEditor WYSIWYG enhancements, added APIs, an improved help page) can be found on the Releases page.In the Drupal community, "core" refers to the collaboratively built codebase that can be extended through contributory modules and for versions prior to Drupal 8 is kept outside of the "sites" folder of a Drupal installation.The name came from the now-defunct Web site, whose code slowly evolved into Drupal.Buytaert wanted to call the site "dorp" (Dutch for "village") for its community aspects, but mistyped it when checking the domain name and thought the error sounded better. Dean Space used open-source sharing of Drupal to support a decentralized network of approximately 50 disparate, unofficial pro-Dean websites that allowed users to communicate directly with one another as well as with the campaign.The Drupal theming system utilizes a template engine to further separate HTML/CSS from PHP.A popular Drupal contributed module called 'Devel' provides GUI information to developers and themers about the page build.
Bootstrap and Common libraries are defined as Drupal core and all other functionality is defined as Drupal modules including the system module itself.The Drupal core installation can serve as a simple Web site, a single- or multi-user blog, an Internet forum, or a community Web site providing for user-generated content.Drupal also describes itself as a Web application framework.Prior to version 7, Drupal had functions that performed tasks related to databases, such as SQL query cleansing, multi-site table name prefixing, and generating proper SQL queries.In particular, Drupal 6 introduced an abstraction layer that allowed programmers to create SQL queries without writing SQL.It's important to update quickly after security updates are released.Before updating it is highly recommended to take backup of core, modules, theme, files and database.Drupal 7 extends the data abstraction layer so that a programmer no longer needs to write SQL queries as text strings. Microsoft has written a database driver for their SQL Server.Drupal 7 supports the file-based SQLite database engine, which is part of the standard PHP distribution.Interest in Drupal got a significant boost in 2003 when it helped build "Dean Space" for Howard Dean, one of the candidates in the U. Democratic Party's primary campaign for the 2004 U. After Dean ended his campaign, members of his Web team continued to pursue their interest in developing a Web platform that could aid political activism by launching Civic Space Labs in July 2004, "..first company with full-time employees that was developing and distributing Drupal technology." Drupal 8 includes new features and improvements for both users and developers, including: a revamped user interface; WYSIWYG and in-place editing; improved mobile support; added and improved key contributed modules including Views, Date, and Entity Reference; introduced a new object-oriented backend leveraging Symfony components; revamped configuration management; and improved multilingual support.Drupal 8 rc1 is the collective work of over 3,200 core contributors.
