  890 Backward incompatibilities:
  891 
  892  * The Escaper extension is enabled by default, which means that all displayed
  893    variables are now automatically escaped. You can revert to the previous
  894    behavior by removing the extension via $env->removeExtension('escaper')
  895    or just set the 'autoescape' option to 'false'.
  896  * removed the "without loop" attribute for the "for" tag (not needed anymore
  897    as the Optimizer take care of that for most cases)
  898  * arrays and hashes have now a different syntax
  899      * arrays keep the same syntax with square brackets: [1, 2]
  900      * hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
  901      * support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
  902  * the i18n extension is now part of the Twig Extensions repository
  903 
  904 Changes:
  905 
  906  * added the merge filter
  907  * removed 'is_escaper' option for filters (a left over from the previous version) -- you must use 'is_safe' now instead
  908  * fixed usage of operators as method names (like is, in, and not)
  909  * changed the order of execution for node visitors
  910  * fixed default() filter behavior when used with strict_variables set to on
  911  * fixed filesystem loader compatibility with PHAR files
  912  * enhanced error messages when an unexpected token is parsed in an expression
  913  * fixed filename not being added to syntax error messages
  914  * added the autoescape option to enable/disable autoescaping
  915  * removed the newline after a comment (mimics PHP behavior)
  916  * added a syntax error exception when parent block is used on a template that does not extend another one
  917  * made the Escaper extension enabled by default
  918  * fixed sandbox extension when used with auto output escaping
  919  * fixed escaper when wrapping a Twig_Node_Print (the original class must be preserved)
  920  * added an Optimizer extension (enabled by default; optimizes "for" loops and "raw" filters)
  921  * added priority to node visitors
  922 
  923 * 0.9.9 (2010-11-28)
  924 
  925 Backward incompatibilities:
  926  * the self special variable has been renamed to _self
  927  * the odd and even filters are now tests:
  928      {{ foo|odd }} must now be written {{ foo is odd }}
  929  * the "safe" filter has been renamed to "raw"
  930  * in Node classes,
  931         sub-nodes are now accessed via getNode() (instead of property access)
  932         attributes via getAttribute() (instead of array access)
  933  * the urlencode filter had been renamed to url_encode
  934  * the include tag now merges the passed variables with the current context by default
  935    (the old behavior is still possible by adding the "only" keyword)
  936  * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
  937  * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
  938  * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
  939 
  940 Changes:
  941  * added file and line to Twig_Error_Runtime exceptions thrown from Twig_Template
  942  * changed trans tag to accept any variable for the plural count
  943  * fixed sandbox mode (__toString() method check was not enforced if called implicitly from complex statements)
  944  * added the ** (power) operator
  945  * changed the algorithm used for parsing expressions
  946  * added the spaceless tag
  947  * removed trim_blocks option

  949  * changed all exceptions to extend Twig_Error
  950  * fixed unary expressions ({{ not(1 or 0) }})
  951  * fixed child templates (with an extend tag) that uses one or more imports
  952  * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
  953  * escaping has been rewritten
  954  * the implementation of template inheritance has been rewritten
  955    (blocks can now be called individually and still work with inheritance)
  956  * fixed error handling for if tag when a syntax error occurs within a subparse process
  957  * added a way to implement custom logic for resolving token parsers given a tag name
  958  * fixed js escaper to be stricter (now uses a whilelist-based js escaper)
  959  * added the following filers: "constant", "trans", "replace", "json_encode"
  960  * added a "constant" test
  961  * fixed objects with __toString() not being autoescaped
  962  * fixed subscript expressions when calling __call() (methods now keep the case)
  963  * added "test" feature (accessible via the "is" operator)
  964  * removed the debug tag (should be done in an extension)

  971 
  972 * 0.9.8 (2010-06-28)
  973 
  974 Backward incompatibilities:
  975  * the trans tag plural count is now attached to the plural tag:
  976     old: `{% trans count %}...{% plural %}...{% endtrans %}`
  977     new: `{% trans %}...{% plural count %}...{% endtrans %}`
  978 
  979  * added a way to translate strings coming from a variable ({% trans var %})

  981  * fixed default cache umask
  982  * removed Twig_Template instances from the debug tag output

  986 
  987 * 0.9.7 (2010-06-12)
  988 
  989 Backward incompatibilities:
  990  * changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
  991  * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
  992  * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
  993 
  994  * added self as a special variable that refers to the current template (useful for importing macros from the current template)
  995  * added Twig_Template instance support to the include tag
  996  * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
  997  * added a grammar sub-framework to ease the creation of custom tags
  998  * fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
  999  * removed the Twig_Resource::resolveMissingFilter() method
 1000  * fixed the filter tag which did not apply filtering to included files
 1001  * added a bunch of unit tests

 1009  * added three interfaces: Twig_NodeInterface, Twig_TokenParserInterface, and Twig_FilterInterface
 1010  * changed the generated code to match the new coding standards
 1011  * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
 1012  * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
 1013 
 1014 * 0.9.6 (2010-05-12)
 1015 
 1016  * fixed variables defined outside a loop and for which the value changes in a for loop
 1017  * fixed the test suite for PHP 5.2 and older versions of PHPUnit
 1018  * added support for __call() in expression resolution

 1030 
 1031 * 0.9.5 (2010-01-20)
 1032 
 1033 As for any new release, don't forget to remove all cached templates after
 1034 upgrading.
 1035 
 1036 If you have defined custom filters, you MUST upgrade them for this release. To
 1037 upgrade, replace "array" with "new Twig_Filter_Function", and replace the
 1038 environment constant by the "needs_environment" option:
 1039 
 1040   // before
 1041   'even'   => array('twig_is_even_filter', false),
 1042   'escape' => array('twig_escape_filter', true),
 1043 
 1044   // after
 1045   'even'   => new Twig_Filter_Function('twig_is_even_filter'),
 1046   'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
 1047 
 1048 If you have created NodeTransformer classes, you will need to upgrade them to
 1049 the new interface (please note that the interface is not yet considered
 1050 stable).
 1051 
 1052  * fixed list nodes that did not extend the Twig_NodeListInterface
 1053  * added the "without loop" option to the for tag (it disables the generation of the loop variable)
 1054  * refactored node transformers to node visitors
 1055  * fixed automatic-escaping for blocks
 1056  * added a way to specify variables to pass to an included template
 1057  * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
 1058  * improved the filter system to allow object methods to be used as filters
 1059  * changed the Array and String loaders to actually make use of the cache mechanism
 1060  * included the default filter function definitions in the extension class files directly (Core, Escaper)
 1061  * added the // operator (like the floor() PHP function)
 1062  * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
 1063  * added the in operator (as a syntactic sugar for the in filter)
 1064  * added the following filters in the Core extension: in, range
 1065  * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
 1066  * enhanced some error messages to provide better feedback in case of parsing errors
 1067 
 1068 * 0.9.4 (2009-12-02)
 1069 
 1070 If you have custom loaders, you MUST upgrade them for this release: The
 1071 Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
 1072 been changed (see the source code for more information or the documentation).
 1073 
 1074  * added support for DateTime instances for the date filter
 1075  * fixed loop.last when the array only has one item
 1076  * made it possible to insert newlines in tag and variable blocks
 1077  * fixed a bug when a literal '\n' were present in a template text
 1078  * fixed bug when the filename of a template contains */
 1079  * refactored loaders
 1080 
 1081 * 0.9.3 (2009-11-11)
 1082 
 1083 This release is NOT backward compatible with the previous releases.
 1084 
 1085   The loaders do not take the cache and autoReload arguments anymore. Instead,
 1086   the Twig_Environment class has two new options: cache and auto_reload.
 1087   Upgrading your code means changing this kind of code:
 1088 
 1089       $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
 1090       $twig = new Twig_Environment($loader);
 1091 
 1092   to something like this:
 1093 
 1094       $loader = new Twig_Loader_Filesystem('/path/to/templates');
 1095       $twig = new Twig_Environment($loader, array(
 1096         'cache' => '/path/to/compilation_cache',
 1097         'auto_reload' => true,
 1098       ));
 1099 
 1100  * deprecated the "items" filter as it is not needed anymore
 1101  * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
 1102  * optimized template loading speed
 1103  * removed output when an error occurs in a template and render() is used
 1104  * made major speed improvements for loops (up to 300% on even the smallest loops)
 1105  * added properties as part of the sandbox mode
 1106  * added public properties support (obj.item can now be the item property on the obj object)
 1107  * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
 1108  * fixed bug when \ was used in HTML
 1109 
 1110 * 0.9.2 (2009-10-29)
 1111 
 1112  * made some speed optimizations
 1113  * changed the cache extension to .php
 1114  * added a js escaping strategy

 1116  * changed the filter tag to allow chained filters
 1117  * made lexer more flexible as you can now change the default delimiters
 1118  * added set tag
 1119  * changed default directory permission when cache dir does not exist (more secure)
 1120  * added macro support
 1121  * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
 1122  * made Twig_Autoloader::autoload() a static method
 1123  * avoid writing template file if an error occurs
 1124  * added $ escaping when outputting raw strings
 1125  * enhanced some error messages to ease debugging

 1133   * made small speed optimizations
 1134   * made minor tweaks to allow better extensibility and flexibility
 1135 
 1136 * 0.9.0 (2009-10-12)
