  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

  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'].

 112
 113 * Backend speedup with merged JavaScript files
 114
 115 All jsLibs, jsFiles and jsFooterFiles are now concatenated by default into
 116 single files depending on type and section (header / footer). This reduces
 117 the webserver requests approximately by one third.

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

 170 * Compression and concatenation of CSS and JavaScript files
 171
 172 New builtin minifcation routines can now be used with config.minifyCSS and
 173 minifyJS to reduce the file size of all files configured in page.includeCSS
 174 and includeJS. Single files can be excluded from compression using the new
 175 option disableCompression. Additionally, files can be concatenated into a
 176 single file using config.concatenateCss and concatenateJs. Please note that
 177 there is only limited support for @charset, @import and @namespace statements
 178 in concatenated CSS files. Furthermore, if minifyCSS/JS is enabled,
 179 $TYPO3_CONF_VARS[FE][compressionLevel] now also affects CSS and JS files in
 180 frontend and applies GZIP compression. This requires the same options as for
 181 [BE][compressionLevel] to be set in .htaccess.

 200 * Switch to caching framework
 201
 202 The caching framework is enabled by default and the old database-only driven
 203 caching is removed. This opens a lot of options for administrators to optimize
 204 cache deployment and performance. Details about configuration options and usage
 205 in own extensions can be found at http://wiki.typo3.org/Caching_framework.
 206
 207
 208 * Caching framework: db backend uses own table namespace
 209
 210 The database backend must not define own tables and table definitions anymore.
 211 Cache tables and table layout of the database backend will created by the
 212 caching framework when needed.
