2 CHANGES & IMPROVEMENTS between TYPO3 4.2 and 4.3
3 (for technical details see ChangeLog)
4 ************************************************************************
6 General
7 =======
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
13 is successful.
15 * The JavaScript framework ExtJS was integrated as common widget library. This
16 collection offers developers an easy but powerful option to create nice looking
17 user interfaces by reusing predefined objects. For example, ExtJS supports grid
18 views, dialog windows and dynamic panels. It is currently used in the TYPO3 Core
19 for the dialog showing that a session in the backend has expired and for the
20 new recycler.
22 * The JavaScript libraries are updated to prototype and 1.8.2.
24 Backend
25 =======
27 * Extension Manager: You can now set a new option "excludeFromUpdates" in every
28 extensions' ext_emconf.php array. This way, it is a) not shown in the
29 list of extensions to update and b) is shown a exclamation mark in order to
30 prevent updates for this extension. This is very useful if you made local changes
31 to an extension and don't want any admin to overwrite them.
33 * The TypoScript editor "t3editor" was enhanced with code-completion. Now you get
34 context-sensitive suggestions about possible properties while entering TypoScript.
36 * The recycling of deleted records is improved since most elements were not removed
37 physically in TYPO3. The recycler offers the possibilities of cleaning up the garbage
38 collection and to restore data again. Based on an ExtJS interface it's possible to
39 get a quick overview of the accordant elements, filter the resultset and execute the
40 desired actions. This new feature is the modernized and core-specific version of the
41 kj_recycler extension, that has been available in the TER for years now.
43 * The permissions on file operations can now be set on a per-group basis. New back-end
44 users now don't have any file permissions by default, since this has moved to back-end
45 user groups and will apply automatically for each new group being created.
46 The default settings for new groups are the following:
47 + Move, delete, rename and create new directories
48 + Upload, copy, move, delete and rename files
49 + Unzip files
51 * The popup telling an user that his session has expired was replaced by a dialog window.
53 * The workspace selector has been turned to an item in the toolbar menu.
55 * The elements shown when creating new content elements (like "regular text element" etc.)
56 can be configured, modified and extended by Page TSconfig "mod.wizards.newContentElement".
58 * The tables shown when creating new records in the Web>List module are grouped by their scope
59 or extension now. The order can be modified by Page TSconfig "mod.wizards.newRecord.order".
61 * Elements on each table in the Web>List module can be collapsed or expanded now.
62 In the view showing a single table with many elements, a pagination helps to
63 get through them.
65 * Uploading files is now available with an optional Flash Uploader which shows a
66 nice widget with information on the upload progress. It makes it possible to select
67 multiple files at once. Enable the Flash Uploader by checking the appropriate checkbox
68 in the User Setup, reload the Backend and make sure that your browser has the
69 latest version of Flash (Flash v9+) installed.
71 * It is possible now to temporarily lock down the backend for system maintenance. Editors
72 will see an overlay with an message notifying them that the backend is locked. When the
73 lock is removed, editors can continue without having to re-login.
74 The lock is enabled by placing this file:
75 typo3conf/LOCK_BACKEND
77 * The backend gateway for manipulating files (uploading, renaming, copying) TCEfile is now
78 separated from the file typo3/tce_file.php and put in a new file and class in
79 typo3/classes/class.typo3_tcefile.php. There is now also a new AJAXid (TYPO3_tcefile::process)
80 to use this functionality in AJAX-based environments as well.
82 Frontend
83 ========
85 * The message log of the admin panel will report failures to set the locale
87 * Integrated functionality of extension jb_status_code into core:
88 It is now possible to specify a redirection code (301, 302, 303 or
89 307) together with a domain redirection in a sys_domain record.
91 * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
92 This option is useful if the installation uses non-TYPO3 applications and links to
93 them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
94 fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
95 administrators can tell TYPO3 to prepend also other directories inside the site root
96 with config.absRefPrefix.
98 * Added new Install tool option named "dbClientCompress". This option will
99 enable MySQL compression for network traffic. This is useful if
100 MySQl is not on the same host as the web server. Do not use this option if MySQL
101 is on the same host because it will only slow down the process. However if MySQL
102 is on another host, this option may improve performance significally.
104 * CSS styled content was split into separate files for each compatibility versions of TYPO3
105 (3.8, 3.9, 4.2 and current). When including the static template of css_styled_content,
106 a specific version must be chosen (also see Compatibility below).
108 Compatibility
109 =============
111 * A deprecation log has been introduced to track calls to deprecated/outdated methods
112 in the TYPO3 Core. Developers have to make sure to adjust their code to avoid using
113 this old functionality since deprecated methods will be removed in future TYPO3 releases!
114 The information can be found in /typo3conf/deprecation_[hash-value].log
116 * The caching system has been revamped. It is not possible to query the cache tables directly.
117 Any compliant extension has to use the new caching framework.
119 * The simulateStaticDocument functionality (URLs like "MyPage.13.0.html" instead of "index.php?id=13")
120 was extracted and put to a separate system extension "simulatestatic".
122 * The frontend editing functionality was extracted into a separate system extension "fe_edit".
124 * The help modules "about" and "cshmanual" were extracted into separate system extensions with the same name.
126 * As mentioned in "Frontend" CSS styled content has been split into several files.
127 The update wizard can switch the versions of the static includes by refering to
128 the TYPO3 compatibility version.
130 Development
131 ===========
133 * t3lib_div::makeInstance now supports singletons. To mark a class as a
134 singleton it must implement the t3lib_singleton interface.
136 * A new caching framework has been added. It allows extensions to store temporary data
137 transparently to different cache back ends (database, file system or memory).
139 * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
140 is useful for plugins who can disallow caching using a TSConfig option (for example,
141 tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
142 huge performance problems. Now plugin simply need to call
143 $this->cObj->convertToUserIntObject() and return immediately without generating any
144 content.
145 Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
146 This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
147 or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
148 example:
149 function main() {
150 ....
151 if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
152 $this->cObj->convertToUserIntObject();
153 return '';
154 }
156 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
157 static function initLanguage($language = 'default');
158 Creates $GLOBALS['LANG'] for the given language
159 static function initTCA();
160 Loads 'ctrl' sections for TCA tables from all installed extensions
161 static function initExtensionTCA($extensionKey);
162 Similar to initTCA() but loads the table only for the given extension
164 * Class t3lib_extMgm has new methods to enhance palettes:
165 t3lib_extMgm::addFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
166 Adds new fields to all palettes of an existing field.
167 t3lib_extMgm::addFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
168 Adds new fields to a palette.
170 * A random byte generator has been added to t3lib_div::generateRandomBytes() which can
171 be used for cryptographic operations in the TYPO3 Core or in any other extension.
173 TypoScript changes
174 ==================
176 * Custom sub categories can be used in TypoScript constants like the following:
177 #customsubcategory=limits=LLL:EXT:devlog/locallang.xml:limits
179 Database changes
180 ================
182 * The database tables cache_hash, cache_pagesections and cache_pages have been
183 changed due to a move to the new caching framework.
185 * Reference indexes storing table names have been extended from 40 to 255 chars
187 * The database table pages_language_overlay was extended by several fields to
188 support an alternative URL or a shortcut dependent on localization.
190 DBAL
191 ====
193 * ...
196 Backend skin
197 ============
199 * ...
202 Speed improvements
203 ==================
205 * PHP classes for frontend plugins are now loaded only if they are used to render
206 content by enabling the "includeLibs" property also for USER objects in TypoScript.
207 In the past, all available class files for frontend plugins were loaded so this new
208 feature increases performance by reducing memory consumption.
210 * TYPO3 now enables client caching of JavaScript, CSS and image files by using .htaccess
211 files in various directories. This may cause problems if mod_expires is not enabled
212 in the Apache configuration. See the FAQ section in the INSTALL.txt about disabling
213 these files if necessary.
215 Important bugfixes
216 ==================
218 * ...
220 Currently unsupported
221 =====================
223 * Missing features concerning the disposal of Inline Relational Record Editing (IRRE)
224 -> Workspaces and Versioning are currently not supported
225 -> FlexForms using the TCA type 'inline' are currently not supported/tested
226 -> Import/Export (sysext tx_impexp) might not work correctly in special cases
