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 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 * The permissions on file operations can now be set on a per-group basis. New back-end
28 users now don't have any file permissions by default, since this has moved to back-end
29 user groups and will apply automatically for each new group being created.
30 The default settings for new groups are the following:
31 + Move, delete, rename and create new directories
32 + Upload, copy, move, delete and rename files
33 + Unzip files
34
35 * The workspace selector has been turned to an item in the toolbar menu.
36
37 * Elements on each table in the Web>List module can be collapsed or expanded now.
38 In the view showing a single table with many elements, a pagination helps to
39 get through them.
40
41 Frontend
42 ========
43
44 * The message log of the admin panel will report failures to set the locale
45
46 * Integrated functionality of extension jb_status_code into core:
47 It is now possible to specify a redirection code (301, 302, 303 or
48 307) together with a domain redirection in a sys_domain record.
49
50 * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
51 This option is useful if the installation uses non-TYPO3 applications and links to
52 them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
53 fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
54 administrators can tell TYPO3 to prepend also other directories inside the site root
55 with config.absRefPrefix.
56
57 * Added new Install tool option named "dbClientCompress". This option will
58 enable MySQL compression for network traffic. This is useful if
59 MySQl is not on the same host as the web server. Do not use this option if MySQL
60 is on the same host because it will only slow down the process. However if MySQL
61 is on another host, this option may improve performance significally.
62
63 Compatibility
64 =============
65
66 * A deprecation log has been introduced to track calls to deprecated/out-dated methods
67 in the TYPO3 Core. Developers have to make sure to adjust their implementation to avoid
68 using these elderly functionality. Deprecated methods will be removed in future TYPO3 releases!
69 The information can be found in /typo3conf/deprecation_[hash-value].log
70
71 * The caching system has been revamped. It is not possible to query the cache tables directly.
72 Any compliant extension has to use the new caching framework.
73
74 * The simulateStaticDocument functionality (URLs like "MyPage.13.0.html" instead of "index.php?id=13")
75 was extracted and put to a separate system extension "simulatestatic".
76
77 * The frontend editing functionality was extracted into a separate system extension "fe_edit".
78
79 * The help modules "about" and "cshmanual" were extracted into separate system extensions with the same name.
80
81 Development
82 ===========
83
84 * t3lib_div::makeInstance now supports singletons. To mark a class as a
85 singleton it must implement the t3lib_singleton interface.
86
87 * A new caching framework has been added. It allows extensions to store temporary data
88 transparently to different cache back ends (database, file system or memory).
89
90 * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
91 is useful for plugins who can disallow caching using a TSConfig option (for example,
92 tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
93 huge performance problems. Now plugin simply need to call
94 $this->cObj->convertToUserIntObject() and return immediately without generating any
95 content.
96 Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
97 This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
98 or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
99 example:
100 function main() {
101 ....
102 if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
103 $this->cObj->convertToUserIntObject();
104 return '';
105 }
106
107 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
108 static function initLanguage($language = 'default');
109 Creates $GLOBALS['LANG'] for the given language
110 static function initTCA();
111 Loads 'ctrl' sections for TCA tables from all installed extensions
112 static function initExtensionTCA($extensionKey);
113 Similar to initTCA() but loads the table only for the given extension
114
115 * Class t3lib_extMgm has new methods to enhance palettes:
116 t3lib_extMgm::addFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
117 Adds new fields to all palettes of an existing field.
118 t3lib_extMgm::addFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
119 Adds new fields to a palette.
120
121 * A random byte generator has been added to t3lib_div::generateRandomBytes() which can
122 be used for cryptographic operations in the TYPO3 Core or in any other extension.
123
124 TypoScript changes
125 ==================
126
127 * Custom sub categories can be used in TypoScript constants like the following:
128 #customsubcategory=limits=LLL:EXT:devlog/locallang.xml:limits
129
130 Database changes
131 ================
132
133 * The database tables cache_hash, cache_pagesections and cache_pages have been
134 changed due to a move to the new caching framework.
135
136 * Reference indexes storing table names have been extended from 40 to 255 chars
137
138 * The database table pages_language_overlay was extended by several fields to
139 support an alternative URL or a shortcut dependent on localization.
140
141 DBAL
142 ====
143
144 * ...
145
146
147 Backend skin
148 ============
149
150 * ...
151
152
153 Speed improvements
154 ==================
155
156 * PHP classes for frontend plugins are now loaded only if they are used to render
157 content by enabling the "includeLibs" property also for USER objects in TypoScript.
158 In the past, all available class files for frontend plugins were loaded so this new
159 feature increases performance by reducing memory consumption.
160
161 * TYPO3 now enables client caching of JavaScript, CSS and image files by using .htaccess
162 files in various directories. This may cause problems if mod_expires is not enabled
163 in the Apache configuration. See the FAQ section in the INSTALL.txt about disabling
164 these files if necessary.
165
166 Important bugfixes
167 ==================
168
169 * ...
170
171 Currently unsupported
172 =====================
173
174 * Missing features concerning the disposal of Inline Relational Record Editing (IRRE)
175 -> Workspaces and Versioning are currently not supported
176 -> FlexForms using the TCA type 'inline' are currently not supported/tested
177 -> Import/Export (sysext tx_impexp) might not work correctly in special cases
