12 ==================
13
14 * Extension Manager: You can now set a new option "excludeFromUpdates" in every
15 every extensions' ext_emconf.php array. This way, it is a) not shown in the
16 list of extensions to update and b) is shown a exclamation mark in order to
17 prevent updates for this extension. This is very useful if you made local changes
18 to an extension and don't want any admin to overwrite them.

66 Frontend features
67 =================
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 $this->cObj->convertToUserIntObject();
83 return '';
84 }
85
86 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
87 public static function initLanguage($language = 'default');
88 Creates $GLOBALS['LANG'] for the given language
89 public static function initTCA();
90 Loads 'ctrl' sections for TCA tables from all installed extensions
91 public static function initExtensionTCA($extensionKey);
92 Similar to initTCA() but loads the table only for the given extension
93
94 * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
95 This option is useful if the installation uses non-TYPO3 applications and links to
96 them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
97 fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
98 administrators can tell TYPO3 to prepend also other directories inside the site root
99 with config.absRefPrefix.
100
101 * Added new Install tool option named "dbClientCompress". This option will
102 enable MySQL compression for network traffic. This is useful if
103 MySQl is not on the same host as the web server. Do not use this option if MySQL
104 is on the same host because it will only slow down the process. However if MySQL
105 is on the other host, this option may impove performance significally.
