+Backward incompatibilities:

+ * added the "empty" test
+
+* 0.9.10 (2010-12-16)
+
+Backward incompatibilities:
+
+ * The Escaper extension is enabled by default, which means that all displayed
+ variables are now automatically escaped. You can revert to the previous
+ behavior by removing the extension via $env->removeExtension('escaper')
+ or just set the 'autoescape' option to 'false'.
+ * removed the "without loop" attribute for the "for" tag (not needed anymore
+ as the Optimizer take care of that for most cases)
+ * arrays and hashes have now a different syntax
+ * arrays keep the same syntax with square brackets: [1, 2]
+ * hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
+ * support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
+ * the i18n extension is now part of the Twig Extensions repository

+
+* 0.9.9 (2010-11-28)
+
+Backward incompatibilities:
+ * the self special variable has been renamed to _self
+ * the odd and even filters are now tests:
+ {{ foo|odd }} must now be written {{ foo is odd }}
+ * the "safe" filter has been renamed to "raw"
+ * in Node classes,
+ sub-nodes are now accessed via getNode() (instead of property access)
+ attributes via getAttribute() (instead of array access)
+ * the urlencode filter had been renamed to url_encode
+ * the include tag now merges the passed variables with the current context by default
+ (the old behavior is still possible by adding the "only" keyword)
+ * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
+ * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
+ * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
+
+Changes:

+ * removed trim_blocks option
+ * added support for is*() methods for attributes (foo.bar now looks for foo->getBar() or foo->isBar())
+ * changed all exceptions to extend Twig_Error
+ * fixed unary expressions ({{ not(1 or 0) }})
+ * fixed child templates (with an extend tag) that uses one or more imports
+ * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
+ * escaping has been rewritten
+ * the implementation of template inheritance has been rewritten
+ (blocks can now be called individually and still work with inheritance)
+ * fixed error handling for if tag when a syntax error occurs within a subparse process
+ * added a way to implement custom logic for resolving token parsers given a tag name
+ * fixed js escaper to be stricter (now uses a whilelist-based js escaper)

+ * fixed Twig_Template::getAttribute() for protected properties
+
+* 0.9.8 (2010-06-28)
+
+Backward incompatibilities:
+ * the trans tag plural count is now attached to the plural tag:
+ old: `{% trans count %}...{% plural %}...{% endtrans %}`
+ new: `{% trans %}...{% plural count %}...{% endtrans %}`
+

+ * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})

+ * changed the generated code to match the new coding standards
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
+ * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
+
+* 0.9.6 (2010-05-12)
+
+ * fixed variables defined outside a loop and for which the value changes in a for loop

+
+* 0.9.5 (2010-01-20)
+
+As for any new release, don't forget to remove all cached templates after
+upgrading.
+
+If you have defined custom filters, you MUST upgrade them for this release. To
+upgrade, replace "array" with "new Twig_Filter_Function", and replace the
+environment constant by the "needs_environment" option:
+
+ // before
+ 'even' => array('twig_is_even_filter', false),
+ 'escape' => array('twig_escape_filter', true),
+
+ // after
+ 'even' => new Twig_Filter_Function('twig_is_even_filter'),
+ 'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
+
+If you have created NodeTransformer classes, you will need to upgrade them to
+the new interface (please note that the interface is not yet considered
+stable).
+
+ * fixed list nodes that did not extend the Twig_NodeListInterface
+ * added the "without loop" option to the for tag (it disables the generation of the loop variable)
+ * refactored node transformers to node visitors
+ * fixed automatic-escaping for blocks
+ * added a way to specify variables to pass to an included template
+ * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
+ * improved the filter system to allow object methods to be used as filters
+ * changed the Array and String loaders to actually make use of the cache mechanism
+ * included the default filter function definitions in the extension class files directly (Core, Escaper)
+ * added the // operator (like the floor() PHP function)
+ * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
+ * added the in operator (as a syntactic sugar for the in filter)
+ * added the following filters in the Core extension: in, range
+ * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
+ * enhanced some error messages to provide better feedback in case of parsing errors
+
+* 0.9.4 (2009-12-02)
+
+If you have custom loaders, you MUST upgrade them for this release: The
+Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
+been changed (see the source code for more information or the documentation).
+
+ * added support for DateTime instances for the date filter
+ * fixed loop.last when the array only has one item
+ * made it possible to insert newlines in tag and variable blocks
+ * fixed a bug when a literal '\n' were present in a template text
+ * fixed bug when the filename of a template contains */
+ * refactored loaders
+
+* 0.9.3 (2009-11-11)
+
+This release is NOT backward compatible with the previous releases.
+
+ The loaders do not take the cache and autoReload arguments anymore. Instead,
+ the Twig_Environment class has two new options: cache and auto_reload.
+ Upgrading your code means changing this kind of code:
+
+ $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
+ $twig = new Twig_Environment($loader);
+
+ to something like this:
+
+ $loader = new Twig_Loader_Filesystem('/path/to/templates');
+ $twig = new Twig_Environment($loader, array(
+ 'cache' => '/path/to/compilation_cache',
+ 'auto_reload' => true,
+ ));
+
+ * deprecated the "items" filter as it is not needed anymore
+ * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
+ * optimized template loading speed
+ * removed output when an error occurs in a template and render() is used
+ * made major speed improvements for loops (up to 300% on even the smallest loops)
+ * added properties as part of the sandbox mode
+ * added public properties support (obj.item can now be the item property on the obj object)
+ * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
+ * fixed bug when \ was used in HTML
+
+* 0.9.2 (2009-10-29)
+
+ * made some speed optimizations

+ * added macro support
+ * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
+ * made Twig_Autoloader::autoload() a static method
+ * avoid writing template file if an error occurs
+ * added $ escaping when outputting raw strings
+ * enhanced some error messages to ease debugging
+ * fixed empty cache files when the template contains an error
+
+* 0.9.1 (2009-10-14)
+
+ * fixed a bug in PHP 5.2.6
+ * fixed numbers with one than one decimal
+ * added support for method calls with arguments ({{ foo.bar('a', 43) }})

+
+* 0.9.0 (2009-10-12)
+
