  13 ===============================================================================
  14 Compatibility
  15 ===============================================================================
  16
  17 * PHP 5.3
  18
  19 This version requires at least PHP 5.3, older versions of PHP are not supported
  20 anymore with TYPO3 4.6.
  21
  22 * ImageMagick/GraphicsMagick
  23
  24 ...
  25
  26 * PHP __constructor() methods
  27
  28 The old PHP 4 style class constructors, which have been the same as the class
  29 name have been changed to use the PHP 5 __constructor() syntax. This is
  30 considered as breaking change if extension called the old contructor of an
  31 object directly.

  34 Changes and improvements
  35 ===============================================================================

  37 This will list all changes and improvements between TYPO3 4.5 and 4.6. For
  38 technical details see ChangeLog included in the typo3_src package.

  46 Removed functionality
  47 -------------------------------------------------------------------------------
  48
  49 * Static Published Pages
  50
  51 The feature to statically publish a page from the Admin Panel has been dropped.
  52 There are better ways to achieve such a functionality, like e.g.
  53 EXT:nc_staticfilecache.
  54
  55 * Removed extCache=2 option
  56
  57 The cache files in typo3conf/temp_CACHED_* were by default set to a hash that
  58 was based on the extensionlist, but this is quite unnecessary, so the extCache
  59 option was removed to be only used once in the typo3conf/ directory in order
  60 to prevent hundreds of temp_CACHED_* files that don't get cleaned up
  61 automatically. From now on the option $TYPO3_CONF_VARS['EXT']['extCache'] can
  62 only be set to 0 or 1.

  70 Other general improvements
  71 -------------------------------------------------------------------------------
  72
  73 * New scheduler task to delete old data from tables
  74
  75 The scheduler task 'Table garbage collection' can be used to delete old data
  76 from growing tables like log tables on a regular basis. Additional tables that
  77 can be cleaned up must be registered in $TYPO3_CONF_VARS['SC_OPTIONS']
  78 ['scheduler']['tasks']['tx_scheduler_TableGarbageCollection']['options']
  79 ['tables'] with its table name and a field. After that they can
  80 be selected in the scheduler task.
  81
  82
  83 * New scheduler task to delete old files from fileadmin trash directories
  84
  85 The scheduler task 'Fileadmin recycler garbage collection' can be used to
  86 definitely delete old files from _recycler_ directories. When a _recycler_
  87 directory exists within the path of a file to delete via the File module, the
  88 file is not actually deleted, but stored in the _recycler_ folder.
  89 This new task now deletes all files insider _recycler_ folders that have been
  90 moved there for longer than a given number of days.
  91
  92 * New option to customize the cookie names used by TYPO3
  93
  94 It is now possible to customize the cookie names used by TYPO3 to avoid clashes
  95 when running more installations on the same domain. The names used can be con-
  96 figured with:
  97 $TYPO3_CONF_VARS['FE']['cookieName'] and
  98 $TYPO3_CONF_VARS['BE']['cookieName'].
  99
 100 * Moved t3d exports to fileadmin/_temp_ directory
 101
 102 t3d packages exported by the import / extbase extension are now stored in
 103 fileadmin/_temp_ by default which is access restricted by default .htaccess
 104 rules.
 105
 106 * Added "IDNA Convert" libray for Internationalized Domain Names (IDN)
 107
 108 The new library can be found in typo3/contrib/idna/ and is used to encode and
 109 decode internationalized domain names (containing special characters like
 110 umlauts) from and to punycode.

 123
 124 * Backend speedup with merged JavaScript files
 125
 126 All jsLibs, jsFiles and jsFooterFiles are now concatenated by default into
 127 single files depending on type and section (header / footer). This reduces
 128 the webserver requests approximately by one third.

 161 Although we do our best to make adjustments in a backwards-compatible manner,
 162 we needed to break backwards compatibility at a few places. In order to see if
 163 you are affected and how the issues can be solved, please read our notes on
 164 breaking changes:

 180
 181 * Compression and concatenation of CSS and JavaScript files
 182
 183 New builtin minification routines can now be used with config.compressCss and
 184 config.compressJs to reduce the file size of all files configured in
 185 page.includeCSS and page.includeJS. Single files can be excluded from
 186 compression using the new option disableCompression. Additionally, files can
 187 be concatenated into a single file using config.concatenateCss and
 188 config.concatenateJs. Please note that there is only limited support for
 189 @charset, @import and @namespace statements in concatenated CSS files.
 190 Furthermore, if compressCss/compressJs is enabled,
 191 $TYPO3_CONF_VARS[FE][compressionLevel] now also affects CSS and JS files in
 192 frontend and applies GZIP compression. This requires the same options as for
 193 [BE][compressionLevel] to be set in .htaccess.

 212 * Switch to caching framework
 213
 214 The caching framework is enabled by default and the old database-only driven
 215 caching is removed. This opens a lot of options for administrators to optimize
 216 cache deployment and performance. Details about configuration options and usage
 217 in own extensions can be found at http://wiki.typo3.org/Caching_framework.
 218
 219
 220 * Caching framework: db backend uses own table namespace
 221
 222 The database backend must not define own tables and table definitions anymore.
 223 Cache tables and table layout of the database backend will created by the
 224 caching framework when needed.
