2 CHANGES & IMPROVEMENTS between TYPO3 4.2 and 4.3
3 (for technical details see ChangeLog)
4 ************************************************************************
9 * TYPO3 requires PHP 5.2 now
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
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.
24 * The TypoScript editor "t3editor" was enhanced with code-completion. Now you get
25 context-sensitive suggestions about possible properties while entering TypoScript.
30 * The message log of the admin panel will report failures to set the locale
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.
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.
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.
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.
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".
58 * The frontend editing functionality was extracted into a separate system extension "frontend_edit".
63 * t3lib_div::makeInstance now supports singletons. To mark a class as a
64 singleton it must implement the t3lib_singleton interface.
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).
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
75 Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
76 This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
77 or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
81 if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
82 $this->cObj->convertToUserIntObject();
86 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
87 static function initLanguage($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
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.
106 * The database tables cache_hash, cache_pagesections and cache_pages have been
107 changed due to a move to the new caching framework.
109 * Reference indexes storing table names have been extended from 40 to 255 chars
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.
136 Currently unsupported
137 =====================
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
