************************************************************************
-CHANGES & IMPROVEMENTS between TYPO3 4.0 and 4.1
+CHANGES & IMPROVEMENTS between TYPO3 4.2 and 4.3
(for technical details see ChangeLog)
************************************************************************
+General
+=======
+
+ * TYPO3 requires PHP 5.2 now
+
+ * Support for OpenID auhentication with a new system extension for both FE and BE.
+ Any user with a valid OpenID identifier may log in when the OpenID authentication
+ is successful.
+
+ * The JavaScript framework ExtJS was integrated as common widget library. This
+ collection offers developers an easy but powerful option to create nice looking
+ user interfaces by reusing predefined objects. For example, ExtJS supports grid
+ views, dialog windows and dynamic panels. It is currently used in the TYPO3 Core
+ for the dialog showing that a session in the backend has expired and for the
+ new recycler.
+
+ * The JavaScript libraries are updated to prototype 1.6.0.3 and script.aculo.us 1.8.2.
+
+ * Integration of RSA Authentication Service: Using a the public-key cryptography allows
+ to transfer sensitive data over a secure channel, even if the website does not support
+ HTTPS. This feature allows to store password data as salted hash value. The RSA
+ authentication service can be used in frontend and backend by enabling the system
+ extension rsaauth.
+ Note: The service requires either the openssl PHP extension, or the openssl binary.
+
+ * Integration of PHP Autoloader: This feature allows to have only those files in memory
+ that are really required for an accordant application. The performace improves
+ dramatically. The PHP files are looked up using a registry file returns a simple array
+ mapping PHP class names to accordant file names:
+ + t3lib/core_autoload.php contains all classes in t3lib/tslib or the TYPO3 Core
+ + [extension_key]/ext_autoload.php contains all classes of that TYPO3 extension
+
+ * Extbase and Fluid integration: Extbase and Fluid are backports from FLOW3 to bring MVC
+ and a very flexible templating engine to TYPO3 4.x. Extbase can be used in TYPO3 4.3 for
+ frontend extensions only. The techniques used by these two packages are the same as in
+ FLOW3/TYPO3 5.0 - thus, it's possible to develop future-proof extensions now and migrate
+ them easily when TYPO3 5.0 is released.
+
+Backend
+=======
+
+ * Extension Manager: You can now set a new option "excludeFromUpdates" in every
+ extensions' ext_emconf.php array. This way, it is a) not shown in the
+ list of extensions to update and b) is shown a exclamation mark in order to
+ prevent updates for this extension. This is very useful if you made local changes
+ to an extension and don't want any admin to overwrite them.
+
+ * The TypoScript editor "t3editor" was enhanced with code-completion. Now you get
+ context-sensitive suggestions about possible properties while entering TypoScript.
+
+ * The recycling of deleted records is improved since most elements were not removed
+ physically in TYPO3. The recycler offers the possibilities of cleaning up the garbage
+ collection and to restore data again. Based on an ExtJS interface it's possible to
+ get a quick overview of the accordant elements, filter the resultset and execute the
+ desired actions. This new feature is the modernized and core-specific version of the
+ kj_recycler extension, that has been available in the TER for years now.
+
+ * The permissions on file operations can now be set on a per-group basis. New back-end
+ users now don't have any file permissions by default, since this has moved to back-end
+ user groups and will apply automatically for each new group being created.
+ The default settings for new groups are the following:
+ + Move, delete, rename and create new directories
+ + Upload, copy, move, delete and rename files
+ + Unzip files
+
+ * The popup telling an user that his session has expired was replaced by a dialog window.
+
+ * The workspace selector has been turned to an item in the toolbar menu.
+
+ * The elements shown when creating new content elements (like "regular text element" etc.)
+ can be configured, modified and extended by Page TSconfig "mod.wizards.newContentElement".
+
+ * The tables shown when creating new records in the Web>List module are grouped by their scope
+ or extension now. The order can be modified by Page TSconfig "mod.wizards.newRecord.order".
+
+ * Elements on each table in the Web>List module can be collapsed or expanded now.
+ In the view showing a single table with many elements, a pagination helps to
+ get through them.
+
+ * Uploading files is now available with an optional Flash Uploader which shows a
+ nice widget with information on the upload progress. It makes it possible to select
+ multiple files at once. Enable the Flash Uploader by checking the appropriate checkbox
+ in the User Setup, reload the Backend and make sure that your browser has the
+ latest version of Flash (Flash v9+) installed.
+
+ * It is possible now to temporarily lock down the backend for system maintenance. Editors
+ will see an overlay with an message notifying them that the backend is locked. When the
+ lock is removed, editors can continue without having to re-login.
+ The lock is enabled by placing this file:
+ typo3conf/LOCK_BACKEND
+
+ * The backend gateway for manipulating files (uploading, renaming, copying) TCEfile is now
+ separated from the file typo3/tce_file.php and put in a new file and class in
+ typo3/classes/class.typo3_tcefile.php. There is now also a new AJAXid (TYPO3_tcefile::process)
+ to use this functionality in AJAX-based environments as well.
+
+ * The backend login page is now localized. The language for the login page where no
+ user-defined language is available yet is detected by the preferred browser language. If you
+ have previously changed the login labels via $TYPO3_CONF_VARS['BE']['loginLabels'] then
+ these will be used, however it is recommended to overload the XML file with your own XML file
+ and $TYPO3_CONF_VARS['BE']['XLLfile']['EXT:lang/locallang_login.xml']. These will only be used
+ once you remove the altered "loginLabels" configuration option from typo3conf/localconf.php.
+
+Frontend
+========
+
+ * The message log of the admin panel will report failures to set the locale
+
+ * Integrated functionality of extension jb_status_code into core:
+ It is now possible to specify a redirection code (301, 302, 303 or
+ 307) together with a domain redirection in a sys_domain record.
+
+ * Added option named "additionalAbsRefPrefixDirectories" for Frontend in the Install tool.
+ This option is useful if the installation uses non-TYPO3 applications and links to
+ them from extensions. Earlier TYPO3 prepended only media/, typo3conf/ext/ and
+ fileadmin/ directories automatically with config.absRefPrefix. Using the new variable
+ administrators can tell TYPO3 to prepend also other directories inside the site root
+ with config.absRefPrefix.
+
+ * Added new Install tool option named "dbClientCompress". This option will
+ enable MySQL compression for network traffic. This is useful if
+ MySQl is not on the same host as the web server. Do not use this option if MySQL
+ is on the same host because it will only slow down the process. However if MySQL
+ is on another host, this option may improve performance significally.
+
+ * CSS styled content was split into separate files for each compatibility versions of TYPO3
+ (3.8, 3.9, 4.2 and current). When including the static template of css_styled_content,
+ a specific version must be chosen (also see Compatibility below).
+
+ * The GIFBUILDER now supports automatic line breaks by defining a maximum width of the
+ element to be rendered. The new TypoScript properties are "breakWidth" and "breakSpace".
+
+ * Image rendering now cuts off the profile data of images by default to reduce file sizes.
+ This behaviour can be modified or disabled by changing [GFX][im_stripProfileCommand] in
+ the install tool or by setting the TypoScript property "stripProfile" on IMAGE objects.
+
Compatibility
=============
- * captionSplit.cObject had been removed in version 4.0. For compatibility reasons, it has been added again, though it remains deprecated and should not be used anymore (bug #3005)
- * In TYPO3 4.0, showpic.php automatically adds default parameters to custom URLs. Some extensions did not like this feature because they want to generate all parameters by themselves. Enabling JSwindow.altUrl_noDefaultParams will now solve this problem for them (bug #1153)
- * FORM submit buttons with images are now valid xhtml (bug #3397)
+ * A deprecation log has been introduced to track calls to deprecated/outdated methods
+ in the TYPO3 Core. Developers have to make sure to adjust their code to avoid using
+ this old functionality since deprecated methods will be removed in future TYPO3 releases!
+ The information can be found in /typo3conf/deprecation_[hash-value].log
+
+ * The caching system has been revamped. It is not possible to query the cache tables directly.
+ Any compliant extension has to use the new caching framework.
+
+ * The simulateStaticDocument functionality (URLs like "MyPage.13.0.html" instead of "index.php?id=13")
+ was extracted and put to a separate system extension "simulatestatic".
+
+ * The frontend editing functionality was extracted into a separate system extension "fe_edit".
+
+ * The help modules "about" and "cshmanual" were extracted into separate system extensions with the same name.
+
+ * As mentioned in "Frontend" CSS styled content has been split into several files.
+ The update wizard can switch the versions of the static includes by refering to
+ the TYPO3 compatibility version.
+
+Development
+===========
+
+ * t3lib_div::makeInstance now supports singletons. To mark a class as a
+ singleton it must implement the t3lib_singleton interface.
+
+ * A new caching framework has been added. It allows extensions to store temporary data
+ transparently to different cache back ends (database, file system or memory).
+
+ * Frontend plugins now can convert themselves from USER to USER_INT on the fly. This
+ is useful for plugins who can disallow caching using a TSConfig option (for example,
+ tt_news). Earlier plugins had to use $GLOBALS['TSFE']->set_no_cache(), which caused
+ huge performance problems. Now plugin simply need to call
+ $this->cObj->convertToUserIntObject() and return immediately without generating any
+ content.
+ Objects can find their current execution mode by calling $this->cObj->getUserObjectType().
+ This function can return either tslib_cObj::OBJECTTYPE_USER (if object runs as USER)
+ or tslib_cObj::OBJECTTYPE_USER_INT (if object is running as USER_INT). Here the code
+ example:
+ function main() {
+ ....
+ if (!$this->conf['allowCaching'] && $this->cObj->getUserObjectType() == tslib_cObj::OBJECTTYPE_USER) {
+ $this->cObj->convertToUserIntObject();
+ return '';
+ }
+
+ * Class tslib_eidtools is enhanced with new methods for eID/AJAX applications:
+ static function initLanguage($language = 'default');
+ Creates $GLOBALS['LANG'] for the given language
+ static function initTCA();
+ Loads 'ctrl' sections for TCA tables from all installed extensions
+ static function initExtensionTCA($extensionKey);
+ Similar to initTCA() but loads the table only for the given extension
+
+ * Class t3lib_extMgm has new methods to enhance palettes:
+ t3lib_extMgm::addFieldsToAllPalettesOfField($table, $field, $addFields, $insertionPosition = '');
+ Adds new fields to all palettes of an existing field.
+ t3lib_extMgm::addFieldsToPalette($table, $palette, $addFields, $insertionPosition = '');
+ Adds new fields to a palette.
+
+ * A random byte generator has been added to t3lib_div::generateRandomBytes() which can
+ be used for cryptographic operations in the TYPO3 Core or in any other extension.
-Installation/Upgrade
-====================
+TypoScript changes
+==================
+
+ * Custom sub categories can be used in TypoScript constants like the following:
+ #customsubcategory=limits=LLL:EXT:devlog/locallang.xml:limits
+
+Database changes
+================
+
+ * The database tables cache_hash, cache_pagesections and cache_pages have been
+ changed due to a move to the new caching framework.
- * The update wizard has been slightly reworded to make the functionality more easy to understand (bug #3943)
- * typo3temp/ subdirectories were not created automatically (bug #2462)
+ * Reference indexes storing table names have been extended from 40 to 255 chars
+
+ * The database table pages_language_overlay was extended by several fields to
+ support an alternative URL or a shortcut dependent on localization.
+
+ * The field t3ver_label has been extended from 40 to 255 chars in the tables
+ pages, pages_language_overlay, sys_template and tt_content.
DBAL
====
- * Improved support for Oracle
- * ADOdb has been updated to version 4.90
- * DBAL now honours the no_pconnect setting
- * Importing dumps using the install tool now works, see manual for tips
- * Code cleanup
- * Updates to the documentation manual
+ * ...
+
Backend skin
============
- * Template modules have been changed to support skins (especially t3skin)
- * The BE admin module has been changed to support skins (especially t3skin)
- * Current page was not highlighted in navigation tree on IE6 (bug #2874)
+ * ...
+
+
+Speed improvements
+==================
+
+ * PHP classes for frontend plugins are now loaded only if they are used to render
+ content by enabling the "includeLibs" property also for USER objects in TypoScript.
+ In the past, all available class files for frontend plugins were loaded so this new
+ feature increases performance by reducing memory consumption.
+
+ * TYPO3 now enables client caching of JavaScript, CSS and image files by using .htaccess
+ files in various directories. This may cause problems if mod_expires is not enabled
+ in the Apache configuration. See the FAQ section in the INSTALL.txt about disabling
+ these files if necessary.
