   2 CHANGES & IMPROVEMENTS between TYPO3 4.2 and 4.3
   3 (for technical details see ChangeLog)
   4 ************************************************************************
   5
   6 General
   7 =======
   8
   9         * TYPO3 requires PHP 5.2 now
  10
  11         * Support for OpenID auhentication with a new system extension for both FE and BE.
  12           Any user with a valid OpenID identifier may log in when the OpenID authentication
  13           is successful.
  14
  15 Backend
  16 =======
  17
  18         * Extension Manager: You can now set a new option "excludeFromUpdates" in every
  19           every extensions' ext_emconf.php array. This way, it is a) not shown in the
  20           list of extensions to update and b) is shown a exclamation mark in order to
  21           prevent updates for this extension. This is very useful if you made local changes
  22           to an extension and don't want any admin to overwrite them.
  23
  24         * The TypoScript editor "t3editor" was enhanced with code-completion. Now you get
  25           context-sensitive suggestions about possible properties while entering TypoScript.
  26
  27 Frontend
  28 ========
  29
  30         * The message log of the admin panel will report failures to set the locale
  31
  32         * Integrated functionality of extension jb_status_code into core:
  33           It is now possible to specify a redirection code (301, 302, 303 or
  34           307) together with a domain redirection in a sys_domain record.
  35
  36         * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
  37           This option is useful if the installation uses non-TYPO3 applications and links to
  38           them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
  39           fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
  40           administrators can tell TYPO3 to prepend also other directories inside the site root
  41           with config.absRefPrefix.
  42
  43         * Added new Install tool option named "dbClientCompress". This option will
  44           enable MySQL compression for network traffic. This is useful if
  45           MySQl is not on the same host as the web server. Do not use this option if MySQL
  46           is on the same host because it will only slow down the process. However if MySQL
  47           is on the other host, this option may impove performance significally.
  48
  49 Compatibility
  50 =============
  51
  52         * The caching system has been revamped. It is not possible to query the cache tables directly.
  53           Any compliant extension has to use the new caching framework.
  54
  55         * The simulateStaticDocument functionality (URLs like "MyPage.13.0.html" instead of "index.php?id=13")
  56           was extracted and put to a separate system extension "simulatestatic".
  57
  58         * The frontend editing functionality was extracted into a separate system extension "frontend_edit".
  59
  60 Development
  61 ===========
  62
  63         * t3lib_div::makeInstance now supports singletons. To mark a class as a
  64           singleton it must implement the t3lib_singleton interface.
  65
  66         * A new caching framework has been added. It allows extensions to store temporary data
  67           transparently to different cache back ends (database, file system or memory).
  68
  69         * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
  70           is useful for plugins who can disallow caching using a TSConfig option (for example,
  71           tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
  72           huge performance problems. Now plugin simply need to call
  73           $this->cObj->convertToUserIntObject() and return immediately without generating any
  74           content.
  75           Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
  76           This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
  77           or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
  78           example:
  79                 function main() {
  80                         ....
  81                         if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
  82                                 $this->cObj->convertToUserIntObject();
  83                                 return '';
  84                         }
  85
  86         * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
  87                 static function initLanguage($language = 'default');
  88                         Creates $GLOBALS['LANG'] for the given language
  89                 static function initTCA();
  90                         Loads 'ctrl' sections for TCA tables from all installed extensions
  91                 static function initExtensionTCA($extensionKey);
  92                         Similar to initTCA() but loads the table only for the given extension
  93
  94         * Class t3lib_extMgm has new methods to enhance palettes:
  95                 t3lib_extMgm::addFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
  96                         Adds new fields to all palettes of an existing field.
  97                 t3lib_extMgm::addFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
  98                         Adds new fields to a palette.
  99
 100 TypoScript changes
 101 ==================
 102
 103 Database changes
 104 ================
 105
 106         * The database tables cache_hash, cache_pagesections and cache_pages have been
 107           changed due to a move to the new caching framework.
 108
 109         * Reference indexes storing table names have been extended from 40 to 255 chars
 110
 111 DBAL
 112 ====
 113
 114         * ...
 115
 116
 117 Backend skin
 118 ============
 119
 120         * ...
 121
 122
 123 Speed improvements
 124 ==================
 125
 126         * PHP classes for frontend plugins are now loaded only if they are used to render
 127           content by enabling the "includeLibs" property also for USER objects in TypoScript.
 128           In the past, all available class files for frontend plugins were loaded so this new
 129           feature increases performance by reducing memory consumption.
 130
 131 Important bugfixes

 133
 134         * ...
 135
 136 Currently unsupported
 137 =====================
 138
 139         * Missing features concerning the disposal of Inline Relational Record Editing (IRRE)
 140                 -> Workspaces and Versioning are currently not supported
 141                 -> FlexForms using the TCA type 'inline' are currently not supported/tested
 142                 -> Import/Export (sysext tx_impexp) might not work correctly in special cases
