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 Frontend
25 ========
26
27 * The message log of the admin panel will report failures to set the locale
28
29 * Integrated functionality of extension jb_status_code into core:
30 It is now possible to specify a redirection code (301, 302, 303 or
31 307) together with a domain redirection in a sys_domain record.
32
33 * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
34 This option is useful if the installation uses non-TYPO3 applications and links to
35 them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
36 fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
37 administrators can tell TYPO3 to prepend also other directories inside the site root
38 with config.absRefPrefix.
39
40 * Added new Install tool option named "dbClientCompress". This option will
41 enable MySQL compression for network traffic. This is useful if
42 MySQl is not on the same host as the web server. Do not use this option if MySQL
43 is on the same host because it will only slow down the process. However if MySQL
44 is on the other host, this option may impove performance significally.
45
46 Compatibility
47 =============
48
49 * The caching system has been revamped. It is not possible to query the cache tables directly.
50 Any compliant extension has to use the new caching framework.
51
52 Development
53 ===========
54
55 * t3lib_div::makeInstance now supports singletons. To mark a class as a
56 singleton it must implement the t3lib_singleton interface.
57
58 * A new caching framework has been added. It allows extensions to store temporary data
59 transparently to different cache back ends (database, file system or memory).
60
61 * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
62 is useful for plugins who can disallow caching using a TSConfig option (for example,
63 tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
64 huge performance problems. Now plugin simply need to call
65 $this->cObj->convertToUserIntObject() and return immediately without generating any
66 content.
67 Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
68 This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
69 or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
70 example:
71 function main() {
72 ....
73 if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
74 $this->cObj->convertToUserIntObject();
75 return '';
76 }
77
78 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
79 static function initLanguage($language = 'default');
80 Creates $GLOBALS['LANG'] for the given language
81 static function initTCA();
82 Loads 'ctrl' sections for TCA tables from all installed extensions
83 static function initExtensionTCA($extensionKey);
84 Similar to initTCA() but loads the table only for the given extension
85
86 * Class t3lib_extMgm has new methods to enhance palettes:
87 t3lib_extMgm::addNewFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
88 Adds new fields to all palettes of an existing field.
89 t3lib_extMgm::addNewFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
90 Adds new fields to a palette.
91
92 TypoScript changes
93 ==================
94
95 Database changes
96 ================
97
98 * The database tables cache_hash, cache_pagesections and cache_pages have been
99 changed due to a move to the new caching framework.
