[edit] CMS Libraries and Platform Version

[edit] JFTP

• All class members except JFTP::$instances have become private

[edit] JError

• JError::$_error has become protected

[edit] JRequest

• JRequest::_cleanArray() has been removed

[edit] JArchive

• The following class member have become private:
  • JArchiveGzip:: $_flags
  • JArchiveGzip:: $_data
  • JArchiveTar:: $_types
  • JArchiveTar:: $_flags
  • JArchiveTar:: $_data
  • JArchiveTar:: $_metadata
  • JArchiveZip:: $_methods
  • JArchiveZip:: $_ctrlDirHeader
  • JArchiveZip:: $_ctrlDirEnd
  • JArchiveZip:: $_fileHeader
  • JArchiveZip:: $_data

[edit] JSimpleXML

• The following class members have become private:
  • JSimpleXML:: $_parser
  • JSimpleXML:: $_xml
  • JSimpleXML:: $_stack

[edit] JComponentHelper

• In JComponentHelper::renderComponent the execution of the component is moved to the new function JComponentHelper::executeComponent. This means that a component cannot change or use any of the (internal) variables of renderComponent that might be used by the function later on, like $task or $option. Solution is to get the values, via JRequest, in the component itself.

[edit] Plug-in events

• onPrepareUserProfileData has been removed. Instead respond to onContentPrepareData with a context of com_users.profile

[edit] JUser

The Associative array of user groups for a user no longer contains the group name, but only the group id in both the key and value. The names of groups for a user can be obtained from getGroupsByUser in JAccess.

<type>plugin</type>
<folder>content</folder>
<client>0</client>
