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 * 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.
21
22 * The JavaScript libraries are updated to prototype 1.6.0.3 and script.aculo.us 1.8.2.
23
24 * Integration of RSA Authentication Service: Using a the public-key cryptography allows
25 to transfer sensitive data over a secure channel, even if the website does not support
26 HTTPS. This feature allows to store password data as salted hash value.
27
28 * Integration of PHP Autoloader: This feature allows to have only those files in memory
29 that are really required for an accordant application. The performace improves
30 dramatically. The PHP files are looked up using a registry file returns a simple array
31 mapping PHP class names to accordant file names:
32 + t3lib/core_autoload.php contains all classes in t3lib/tslib or the TYPO3 Core
33 + [extension_key]/ext_autoload.php contains all classes of that TYPO3 extension
34
35 * Extbase and Fluid integration: Extbase and Fluid are backports from FLOW3 to bring MVC
36 and a very flexible templating engine to TYPO3 4.x. Extbase can be used in TYPO3 4.3 for
37 frontend extensions only. The techniques used by these two packages are the same as in
38 FLOW3/TYPO3 5.0 - thus, it's possible to develop future-proof extensions now and migrate
39 them easily when TYPO3 5.0 is released.
40
41 Backend
42 =======
43
44 * Extension Manager: You can now set a new option "excludeFromUpdates" in every
45 extensions' ext_emconf.php array. This way, it is a) not shown in the
46 list of extensions to update and b) is shown a exclamation mark in order to
47 prevent updates for this extension. This is very useful if you made local changes
48 to an extension and don't want any admin to overwrite them.
49
50 * The TypoScript editor "t3editor" was enhanced with code-completion. Now you get
51 context-sensitive suggestions about possible properties while entering TypoScript.
52
53 * The recycling of deleted records is improved since most elements were not removed
54 physically in TYPO3. The recycler offers the possibilities of cleaning up the garbage
55 collection and to restore data again. Based on an ExtJS interface it's possible to
56 get a quick overview of the accordant elements, filter the resultset and execute the
57 desired actions. This new feature is the modernized and core-specific version of the
58 kj_recycler extension, that has been available in the TER for years now.
59
60 * The permissions on file operations can now be set on a per-group basis. New back-end
61 users now don't have any file permissions by default, since this has moved to back-end
62 user groups and will apply automatically for each new group being created.
63 The default settings for new groups are the following:
64 + Move, delete, rename and create new directories
65 + Upload, copy, move, delete and rename files
66 + Unzip files
67
68 * The popup telling an user that his session has expired was replaced by a dialog window.
69
70 * The workspace selector has been turned to an item in the toolbar menu.
71
72 * The elements shown when creating new content elements (like "regular text element" etc.)
73 can be configured, modified and extended by Page TSconfig "mod.wizards.newContentElement".
74
75 * The tables shown when creating new records in the Web>List module are grouped by their scope
76 or extension now. The order can be modified by Page TSconfig "mod.wizards.newRecord.order".
77
78 * Elements on each table in the Web>List module can be collapsed or expanded now.
79 In the view showing a single table with many elements, a pagination helps to
80 get through them.
81
82 * Uploading files is now available with an optional Flash Uploader which shows a
83 nice widget with information on the upload progress. It makes it possible to select
84 multiple files at once. Enable the Flash Uploader by checking the appropriate checkbox
85 in the User Setup, reload the Backend and make sure that your browser has the
86 latest version of Flash (Flash v9+) installed.
87
88 * It is possible now to temporarily lock down the backend for system maintenance. Editors
89 will see an overlay with an message notifying them that the backend is locked. When the
90 lock is removed, editors can continue without having to re-login.
91 The lock is enabled by placing this file:
92 typo3conf/LOCK_BACKEND
93
94 * The backend gateway for manipulating files (uploading, renaming, copying) TCEfile is now
95 separated from the file typo3/tce_file.php and put in a new file and class in
96 typo3/classes/class.typo3_tcefile.php. There is now also a new AJAXid (TYPO3_tcefile::process)
97 to use this functionality in AJAX-based environments as well.
98
99 Frontend
100 ========
101
102 * The message log of the admin panel will report failures to set the locale
103
104 * Integrated functionality of extension jb_status_code into core:
105 It is now possible to specify a redirection code (301, 302, 303 or
106 307) together with a domain redirection in a sys_domain record.
107
108 * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
109 This option is useful if the installation uses non-TYPO3 applications and links to
110 them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
111 fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
112 administrators can tell TYPO3 to prepend also other directories inside the site root
113 with config.absRefPrefix.
114
115 * Added new Install tool option named "dbClientCompress". This option will
116 enable MySQL compression for network traffic. This is useful if
117 MySQl is not on the same host as the web server. Do not use this option if MySQL
118 is on the same host because it will only slow down the process. However if MySQL
119 is on another host, this option may improve performance significally.
120
121 * CSS styled content was split into separate files for each compatibility versions of TYPO3
122 (3.8, 3.9, 4.2 and current). When including the static template of css_styled_content,
123 a specific version must be chosen (also see Compatibility below).
124
125 Compatibility
126 =============
127
128 * A deprecation log has been introduced to track calls to deprecated/outdated methods
129 in the TYPO3 Core. Developers have to make sure to adjust their code to avoid using
130 this old functionality since deprecated methods will be removed in future TYPO3 releases!
131 The information can be found in /typo3conf/deprecation_[hash-value].log
132
133 * The caching system has been revamped. It is not possible to query the cache tables directly.
134 Any compliant extension has to use the new caching framework.
135
136 * The simulateStaticDocument functionality (URLs like "MyPage.13.0.html" instead of "index.php?id=13")
137 was extracted and put to a separate system extension "simulatestatic".
138
139 * The frontend editing functionality was extracted into a separate system extension "fe_edit".
140
141 * The help modules "about" and "cshmanual" were extracted into separate system extensions with the same name.
142
143 * As mentioned in "Frontend" CSS styled content has been split into several files.
144 The update wizard can switch the versions of the static includes by refering to
145 the TYPO3 compatibility version.
146
147 Development
148 ===========
149
150 * t3lib_div::makeInstance now supports singletons. To mark a class as a
151 singleton it must implement the t3lib_singleton interface.
152
153 * A new caching framework has been added. It allows extensions to store temporary data
154 transparently to different cache back ends (database, file system or memory).
155
156 * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
157 is useful for plugins who can disallow caching using a TSConfig option (for example,
158 tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
159 huge performance problems. Now plugin simply need to call
160 $this->cObj->convertToUserIntObject() and return immediately without generating any
161 content.
162 Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
163 This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
164 or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
165 example:
166 function main() {
167 ....
168 if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
169 $this->cObj->convertToUserIntObject();
170 return '';
171 }
172
173 * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
174 static function initLanguage($language = 'default');
175 Creates $GLOBALS['LANG'] for the given language
176 static function initTCA();
177 Loads 'ctrl' sections for TCA tables from all installed extensions
178 static function initExtensionTCA($extensionKey);
179 Similar to initTCA() but loads the table only for the given extension
180
181 * Class t3lib_extMgm has new methods to enhance palettes:
182 t3lib_extMgm::addFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
183 Adds new fields to all palettes of an existing field.
184 t3lib_extMgm::addFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
185 Adds new fields to a palette.
186
187 * A random byte generator has been added to t3lib_div::generateRandomBytes() which can
188 be used for cryptographic operations in the TYPO3 Core or in any other extension.
189
190 TypoScript changes
191 ==================
192
193 * Custom sub categories can be used in TypoScript constants like the following:
194 #customsubcategory=limits=LLL:EXT:devlog/locallang.xml:limits
195
196 Database changes
197 ================
198
199 * The database tables cache_hash, cache_pagesections and cache_pages have been
200 changed due to a move to the new caching framework.
201
202 * Reference indexes storing table names have been extended from 40 to 255 chars
203
204 * The database table pages_language_overlay was extended by several fields to
205 support an alternative URL or a shortcut dependent on localization.
206
207 DBAL
208 ====
209
210 * ...
211
212
213 Backend skin
214 ============
215
216 * ...
217
218
219 Speed improvements
220 ==================
221
222 * PHP classes for frontend plugins are now loaded only if they are used to render
223 content by enabling the "includeLibs" property also for USER objects in TypoScript.
224 In the past, all available class files for frontend plugins were loaded so this new
225 feature increases performance by reducing memory consumption.
226
227 * TYPO3 now enables client caching of JavaScript, CSS and image files by using .htaccess
228 files in various directories. This may cause problems if mod_expires is not enabled
229 in the Apache configuration. See the FAQ section in the INSTALL.txt about disabling
230 these files if necessary.
231
232 Important bugfixes
233 ==================
234
235 * ...
236
237 Currently unsupported
238 =====================
239
240 * Missing features concerning the disposal of Inline Relational Record Editing (IRRE)
241 -> Workspaces and Versioning are currently not supported
242 -> FlexForms using the TCA type 'inline' are currently not supported/tested
243 -> Import/Export (sysext tx_impexp) might not work correctly in special cases
