 General

-       * TYPO3 requires PHP 5.2 now
-
-       * Versioning: "Page" and "Branch" versioning has been disabled for all installations, because it is deprecated since TYPO3 4.2. If you still use one of these versioning types, make sure to set $TYPO3_CONF_VARS['BE']['elementVersioningOnly'] = FALSE in your localconf.php. Please be aware that this option will vanish with TYPO3 4.6 and that "Page" and "Branch" versioning is neither supported nor maintained any longer.
-
-       * Versioning: The dummy "draft workspace" has been disabled for all installations. If you need it you can enable it again in the extension configuration of the "version" extension.
-
-       * There is now a complete new Backend skin for all backend modules, the login screen and the install tool. It is still called "t3skin", however due to the use of icon sprites and the refactoring of the CSS files, it is not possible anymore to run the TYPO3 backend with the old backend skin (from 3.x), the t3skin look and feel from the previous 4.x versions can be obtained by the TER, but is not actively maintained anymore.
-
-       * The static templates for some basic designs that were part of the TYPO3 Core since TYPO3 3.5 are now moved to a system extension that is not included by default. If you are using one of these templates (GLUECK, GREEN, CANDIDATE etc) or one of the old table-based layouts for rendering content (like content (default) or plaintext rendering), make sure to install the system extension via the TYPO3 Installer.
-
-       * The RTE has undergone major changes as UI components have been transformed into ExtJS widgets:
-               1. The RTE framework becomes an ExtJS Panel comprising the toolbar, the iframe, the textarea and the status bar. All components are ExtJS objects.
-               2. When BE textareas are resizable, the framework is resizable as a whole. In the FE, the framework is always resizable.
+       * Versioning: "Page" and "Branch" versioning has been disabled for all
+         installations, because it is deprecated since TYPO3 4.2. If you still
+         use one of these versioning types, make sure to set
+         $TYPO3_CONF_VARS['BE']['elementVersioningOnly'] = FALSE in your
+         localconf.php. Please be aware that this option will vanish with

+         installations. If you need it you can enable it again in the
+         extension configuration of the "version" extension.
+
+       * All CSS and JS files in the TYPO3 Backend are compressed now. This 
+         means that they are added up to a single file without unnecessary
+         whitespace. This will reduce the count of requests drastically, which
+         eventually leads to faster loading and better performance.
+         CAUTION: If compressionLevel is configured 
+         ($TYPO3_CONF_VARS[TYPO3_MODE]['compressionLevel'] = 1 [1-9 for compression
+         level or TRUE for "enabled"]) the files will be served with gzip compression.
+         Be sure to enable / uncomment the needed configuration in your .htaccess file, 
+         also found in misc/advanced.htaccess.
+
+               <FilesMatch "\.js\.gzip$">
+                 AddType "text/javascript" .gzip

+               AddEncoding gzip .gzip
+               
+         IMPORTANT: If you have any trouble accessing the Backend after upgrading
+         to TYPO3 4.4, make sure to clear the typo3temp/ directory manually or through
+         the TYPO3 install tool.
+
+       * There is now a complete new Backend skin for all backend modules, 
+         the login screen and the install tool. It is still called "t3skin",
+         however due to the use of icon sprites and the refactoring of the
+         CSS files, it is not possible anymore to run the TYPO3 Backend
+         with the old backend skin (from 3.x) or with the look and feel from 
+         previous 4.x versions.
+         If you have not installed any skins in your system, you will now see 
+         a completely unstyled TYPO3 Backend, no unneeded additional styles
+         are loaded.
+
+       * The static templates for some basic designs, that were part of the
+         TYPO3 Core since TYPO3 3.5 are now moved to a system extension that
+         is not included by default. If you are using one of these templates
+         (GLUECK, GREEN, CANDIDATE etc) or one of the old table-based layouts
+         for rendering content (like content (default) or plaintext rendering),

                3. The toolbar dropdowns become ExtJS ComboBoxes.
                4. The context menu becomes a configurable ExtJS Menu.
                5. Color palettes become ExtJS ColorPalettes.
                6. All dialogue windows become ExtJS windows.

-       * The install tool is visually refactored and updated. It has now a different look&feel when accessing from outside the TYPO3 Backend and from within to be integrated better in the backend. Also, the 1-2-3 installer process is now cleaned up to be in sync with the new UI elements. There is a new hook in the installing process that allows to add or modify the existing steps in the installer to add more configuration options to a custom TYPO3 installation.

-       * The task center module in the TYPO3 Backend has undergone a complete refactoring, both visually and code-wise.

+
+       * Automatic version-numbers of CSS and JS files to avoid caching problems:
+         This feature provides automatic numbering of CSS and JS files using the
+         files modified timestamp. This way the file reference will change when a
+         CSS or JS files is changed, and by this the browser and proxy will re-cache
+         the file. This feature can be configured to include the timestamp within the
+         filename (before .ext) or as a parameter to the file (default).
+         If versioning is done directly inside the filename (by setting
+         $TYPO3_CONF_VARS[BE][versionNumberInFilename] = TRUE) you need the
+         following line as the first rewrite rule in .htaccess:

 Backend

 Backend
 =======
 

-       * The TYPO3 Backend was moved into an ExtJS Viewport. This is one of the first steps in a sequence to ExtJSify the complete backend. Currently this gives you the possibility to create your own left sidebar (like the pagetree) in your backend modules. Also you can extend the viewport easily with own code to create e.g. a collapsable module menu. More Informations can be found in the TYPO3 Wiki and the official ExtJS viewport documentation. See these links: http://wiki.typo3.org/index.php/TYPO3Viewport and http://www.extjs.com/deploy/dev/docs/
-       
-       * Inline Records (IRRE Elements) are now loaded on demand, which is only when they are opened. This should speed up the editing process drastically.  
-
-       * The t3editor code completion DB was updated to reflect the latest additions. Also the syntax highlighting engine was now extracted from the system extension so it can be used in other places of the TYPO3 Core as well.
-
-       * A donate notice will be shown to admins in the TYPO3 backend after using it for more than three months.
-         This behaviour can be disabled completely - see $TYPO3_CONF_VARS[BE][allowDonateWindow].
-
-       * Most Icons used in the TYPO3 Backend are now rendered through so-called sprites. Instead of loading many image tags with single icons and therefore many http requests we now just have 6 sprites (one big image with all icons included) that need to be loaded. Image tags got replaced by spans using the big sprite images with background and offset. This reduces the HTTP and fileheader overhead of about 90% which results in a blasting fast Backend. For details about the new icon sprite API, have a look at t3lib/class.t3lib_iconworks.php.
-
-       * The "bigButtons" (Edit page properties, Move page, ...) in the Page module are now disabled by default to have a cleaner interface. The old behavior can be restored by setting mod.web_layout.disableBigButtons = 0 in UserTS or PageTS.
-       
-       * The interface "backend_old" was completely removed. This was the BE interface from 4.1. As it wasn't maintained and didn't worked correct, all references are removed, so remaining interfaces for login are backend and frontend. 
-
-       * The extension manager option "Enable extensions without review (basic security check)" was completely removed as most extensions in TER weren't reviewed anyway. Thus, when searching for an extension in TER through the extension manager, all matching extensions, not regarding the review state, are shown up.

-       * Extbase: has been updated to support "Single Table Inheritance" which is a breaking change.  In TYPO3 4.3, Extbase made a "best guess" for the table name if it was not the lowercased class name (simply by crawling the class hierarchy upwards trying to find a mapping rule or table). This "magic" was removed because It was very hard to understand what was happening; especially if there was an error. This behaviour is now changed and you define the recordType and the tableName through TypoScript now. See the typo3.projecty.typo3v4mvc mailing list for more details on this topic.
-
-       * Extbase: Template filenames are expected to be UpperCamelCased from now on. Before, they were expected to be all lowercase. For a grace period there is still a fallback mechanism, so that your old template filenames will still work. But you should rename your templates from "myaction.html" to "MyAction.html" to make sure, that it still works in upcoming versions of Fluid!  A message to the deprecation log is generated in case an "old" template name is found.
-
-       * Support for GDlib 1.x was completely dropped, only GDlib 2.x is supported, which is bundled with most PHP installations.

If you still use one of these versioning types, make sure to set $TYPO3_CONF_VARS['BE']['elementVersioningOnly'] = FALSE in your localconf.php. Please be aware that this option will vanish with TYPO3 4.6 and that "Page" and "Branch" versioning is neither supported nor maintained any longer.

 Backend skin
 ============
 
 
 
 Backend skin
 ============
 

-       * There is now a complete new Backend skin for all backend modules, the login screen and the install tool. It is still called "t3skin", however due to the use of icon sprites and the refactoring of the CSS files, it is not possible anymore to run the TYPO3 backend with the old backend skin (from 3.x), the t3skin look and feel from the previous 4.x versions can be obtained by the TER, but is not actively maintained anymore.
-
-       * Skins now have to register themselves by adding an entry $TBE_STYLES['skins'][$_EXTKEY]. By default, all CSS files from subdirectories stylesheets/structure/ and stylesheets/visual/ are included, additional directories can be added by setting $TBE_STYLES['skins'][$_EXTKEY]['stylesheetDirectories'].
-
-       * Most Icons used in the TYPO3 Backend are now rendered through so-called sprites. Instead of loading many image tags with single icons and therefore many http requests we now just have 6 sprites (one big image with all icons included) that need to be loaded. Image tags got replaced by spans using the big sprite images with background and offset. This reduces the HTTP and fileheader overhead of about 90% which results in a blasting fast Backend. For details about the new icon sprite API, have a look at t3lib/class.t3lib_iconworks.php.

+         are loaded.
+
+       * CSS files in the TYPO3 Backend are now separated in structure
+         CSS statements (definitions for margin, padding, width, height) and
+         visual (like formatting colors, fonts, border and backgrounds).
