This document is a part of the TYPO3 project. TYPO3 is an open source web content management system released under the GNU GPL. TYPO3 is copyright (c) 1999-2012 by Kasper Skaarhoj. This document contains information about TYPO3 version 6.0 shall be released on October, 2012. An up-to-date version of this document also containing links to further in depth information can be found here: http://wiki.typo3.org/TYPO3_6.0 =============================================================================== Compatibility =============================================================================== * Refactored bootstrap With a bootstrap refactoring the index.php file located in the document root of the installation was changed. If you are running a typo3 core source with a symlink, make sure that this file is also a symlink to the cores index.php, otherwise the frontend will be broken. If index.php is a copy of the source file, make sure to install a fresh version from 6.0 sources. * Deprecated methods Deprecated methods that were initially targeted to be removed in TYPO3 4.8/6.0 have finally been removed. The deprecation log shows which functions were declared to be deprecated and will be removed in the next TYPO3 versions. * Removed classes prior to scheduled deprecation removal t3lib_BEDisplayLog: This class was used only by the old belog module, its functionality is now encapsulated in EXT:belog itself. Since it is very unlikely that the class was used by other external extensions, the file was removed instead of deprecating it. * New XCLASS handling The old way of registering XCLASSes in $TYPO3_CONF_VARS[TYPO3_MODE]['XCLASS'] is deprecated. XCLASSES can now be registered by adding a 'ux_' prefixed entry of the base class to the ext_autoload.php file providing the XCLASS path. The deprecation layer for old class registration can potentially calculate a wrong path so the XCLASS registration can fail now. This can be fixed by addiononally using the new registration scheme through ext_autoload. Extension authors are advised to remove the three line XCLASS statement at the bottom of class files now for any extension with a compatibility for 6.0 and above. More information can be found at http://wiki.typo3.org/Autoload Removed Functionality ------------------------------------------------------------------------------- * Removed doNotLoadInFE flag With TYPO3 4.3 the flag doNotLoadInFE flag was introduced in ext_emconf.php extension files to hint the core that an extension has no frontend functionality. The performance gain of this change in the frontend was minimal. The flag is now removed and the according extList_FE setting in localconf.php has no effect anymore. * Removed system extension simulatestatic The system extension to simulate static documents was removed from the core. @TODO: Issue #36025 must be solved and this note here adapted, otherwise the removal will be reverted. * Removed TypoScript option noBlur The ancient noBlur TypoScript setting for old Browsers (Internet Explorer <= 5.5) was removed without alternative. The setting has no effect anymore and can be removed from custom TypoScript objects, especially MENU. =============================================================================== Changes and Improvements =============================================================================== This will list all changes and improvements between TYPO3 4.7 and 6.0. For technical details see ChangeLog included in the typo3_src package. ------------------------------------------------------------------------------- General ------------------------------------------------------------------------------- * Extbase and fluid always loaded The core extensions 'extbase' and 'fluid' are used in core classes like t3lib and in several important core extensions. Extbase and fluid are now required extensions and always loaded.
