https://github.com/hubzero/hubzero-cms/tree/2.2.1

Changes

• PHP 5.6 minimum requirement
• PHP 7 ready
• migrations directories added to all components and plugins with initial install migrations

• Automatic API endpoints for ORM models - If a component has ORM models, the system will automatically make available API endpoints for the basic CRUD actions. Models must be named as a singular entity and endpoints are reached via the plural of those entity names. For example, if the Blog component has a model named Entry, then the API endpoint would be https://yourhub.org/api/blog/entries.

  Automatic API endpoints will only be available if a component has not already implemented an API interface (i.e., if a component does not have an /api sub-directory).

• Support for un-prefixed component and module directories. This allows for the removal of the redundant com_ and mod_ prefixes on directories.

  old:
  app/components/com_example/
  app/modules/mod_example/
  
  new:
  app/components/example/
  app/modules/example/

  Note: Prefixed directories will be deprecated in the next version.

• Autoloading of PHP files for un-prefixed components. No include or require statements needed. Class namespace directly maps to case insensitive path.

  // Path:
  app/components/example/models/foo.php
  
  // Directly maps to a class of
  Components\Example\Models\Foo
  
  // Calling the class the first time autoloads it, so no include statement is needed:
  class Examples extends SiteController
  {
      public function displayTask()
      {
          $model = new \Components\Example\Models\Foo();
      }
  }
  

• Hubzero\Database\Manager class added. Class is used to manage database connections.

  • Hubzero\Database\Relational::connection property changed from object (Hubzero\Database\Driver) to (string) name of the connection to be resolved by the manager.
  • Hubzero\Database\Driver\Pdo is generic PDO driver class.
  • Hubzero\Database\Driver\Mysql added, extends Driver\Pdo
  • Hubzero\Database\Driver\Sqlite added, extends Driver\Pdo
  • Hubzero\Database\Driver\Pgsql added, extends Driver\Pdo
• Projects now use global activity log.
• core/libraries/simplepie changed to a Composer package
• Hubzero\Database\Table added as temporary replacement for Joomla's JTable
