- JPATH_PLATFORM is now used instead of JPATH_LIBRARIES
JDatabaseQuery is now abstract due of the work done to support new database engines (Windows Azure and Microsoft SQL Server). This means you must use
$db->getQuery(true); to instantiate a query as is the correct practice in Joomla 1.6.
- getHeadData(), setHeadData() and mergeHeadData() are from now on only present in JDocumentHTML. They have been removed from JDocument and JDocumentXML.
- JDocumentHTML::$_links has changed to a multidimensional array. Also the rendering of the link elements has been moved from JDocumentHTML to JDocumentRenderHead.
- A div element with the ID "system-message-container" is always rendered, whether there are messages or not. This ID should not be used in any extension or template.
- The unused parameter $akey has been removed from JURI::buildQuery().
- JLoader can't load files multiple times anymore.
General Coding Principles
Within the new Joomla release cycle, developers need to be conscious of more frequent changes to version numbers. If you are doing hard checks against, for example, a version number exactly equal to "1.6" then as we move to 1.7, those checks may fail with unexpected results. You should ensure that version checks appropriately allow for future increments like 1.7, 1.8, 2.0, 3.0, and so on.
- ↑ Remove getHeadData(), setHeadData() and mergeHeadData() from JDocument since it only applies to JDocumentHTML. (GitHub)
- ↑ Move the rendering of HTML link elements to JDocumentRendererHead. (GitHub)
- ↑ Remove an unused paramet in JURI::buildQuery(). (GitHub)
- ↑ Use include_once instead of include in JLoader (GitHub)
