The changes caused issues + when using Pytest. Due to the difficulty in supporting Python 2 and + :pep:`451` simultaneously, the changes are reverted until 3.0. + :pr:`1182` +- Fix line numbers in error messages when newlines are stripped. + :pr:`1178` +- The special ``namespace()`` assignment object in templates works in + async environments. :issue:`1180` +- Fix whitespace being removed before tags in the middle of lines when + ``lstrip_blocks`` is enabled. :issue:`1138` +- :class:`~nativetypes.NativeEnvironment` doesn't evaluate + intermediate strings during rendering. This prevents early + evaluation which could change the value of an expression. + :issue:`1186` + + +Version 2.11.1 +-------------- + +Released 2020-01-30 + +- Fix a bug that prevented looking up a key after an attribute + (``{{ data.items[1:] }}``) in an async template. :issue:`1141` + + +Version 2.11.0 +-------------- + +Released 2020-01-27 + +- Drop support for Python 2.6, 3.3, and 3.4. This will be the last + version to support Python 2.7 and 3.5. +- Added a new ``ChainableUndefined`` class to support getitem and + getattr on an undefined object. :issue:`977` +- Allow ``{%+`` syntax (with NOP behavior) when ``lstrip_blocks`` is + disabled. :issue:`748` +- Added a ``default`` parameter for the ``map`` filter. :issue:`557` +- Exclude environment globals from + :func:`meta.find_undeclared_variables`. :issue:`931` +- Float literals can be written with scientific notation, like + 2.56e-3. :issue:`912`, :pr:`922` +- Int and float literals can be written with the '_' separator for + legibility, like 12_345. :pr:`923` +- Fix a bug causing deadlocks in ``LRUCache.setdefault``. :pr:`1000` +- The ``trim`` filter takes an optional string of characters to trim. + :pr:`828` +- A new ``jinja2.ext.debug`` extension adds a ``{% debug %}`` tag to + quickly dump the current context and available filters and tests. + :issue:`174`, :pr:`798, 983` +- Lexing templates with large amounts of whitespace is much faster. + :issue:`857`, :pr:`858` +- Parentheses around comparisons are preserved, so + ``{{ 2 * (3 < 5) }}`` outputs "2" instead of "False". + :issue:`755`, :pr:`938` +- Add new ``boolean``, ``false``, ``true``, ``integer`` and ``float`` + tests. :pr:`824` +- The environment's ``finalize`` function is only applied to the + output of expressions (constant or not), not static template data. + :issue:`63` +- When providing multiple paths to ``FileSystemLoader``, a template + can have the same name as a directory. :issue:`821` +- Always return :class:`Undefined` when omitting the ``else`` clause + in a ``{{ 'foo' if bar }}`` expression, regardless of the + environment's ``undefined`` class. Omitting the ``else`` clause is a + valid shortcut and should not raise an error when using + :class:`StrictUndefined`. :issue:`710`, :pr:`1079` +- Fix behavior of ``loop`` control variables such as ``length`` and + ``revindex0`` when looping over a generator. :issue:`459, 751, 794`, + :pr:`993` +- Async support is only loaded the first time an environment enables + it, in order to avoid a slow initial import. :issue:`765` +- In async environments, the ``|map`` filter will await the filter + call if needed. :pr:`913` +- In for loops that access ``loop`` attributes, the iterator is not + advanced ahead of the current iteration unless ``length``, + ``revindex``, ``nextitem``, or ``last`` are accessed. This makes it + less likely to break ``groupby`` results. :issue:`555`, :pr:`1101` +- In async environments, the ``loop`` attributes ``length`` and + ``revindex`` work for async iterators. :pr:`1101` +- In async environments, values from attribute/property access will + be awaited if needed. :pr:`1101` +- :class:`~loader.PackageLoader` doesn't depend on setuptools or + pkg_resources. :issue:`970` +- ``PackageLoader`` has limited support for :pep:`420` namespace + packages. :issue:`1097` +- Support :class:`os.PathLike` objects in + :class:`~loader.FileSystemLoader` and :class:`~loader.ModuleLoader`. + :issue:`870` +- :class:`~nativetypes.NativeTemplate` correctly handles quotes + between expressions. ``"'{{ a }}', '{{ b }}'"`` renders as the tuple + ``('1', '2')`` rather than the string ``'1, 2'``. :issue:`1020` +- Creating a :class:`~nativetypes.NativeTemplate` directly creates a + :class:`~nativetypes.NativeEnvironment` instead of a default + :class:`Environment`. :issue:`1091` +- After calling ``LRUCache.copy()``, the copy's queue methods point to + the correct queue. :issue:`843` +- Compiling templates always writes UTF-8 instead of defaulting to the + system encoding. :issue:`889` +- ``|wordwrap`` filter treats existing newlines as separate paragraphs + to be wrapped individually, rather than creating short intermediate + lines. :issue:`175` +- Add ``break_on_hyphens`` parameter to ``|wordwrap`` filter. + :issue:`550` +- Cython compiled functions decorated as context functions will be + passed the context. :pr:`1108` +- When chained comparisons of constants are evaluated at compile time, + the result follows Python's behavior of returning ``False`` if any + comparison returns ``False``, rather than only the last one. + :issue:`1102` +- Tracebacks for exceptions in templates show the correct line numbers + and source for Python >= 3.7. :issue:`1104` +- Tracebacks for template syntax errors in Python 3 no longer show + internal compiler frames. :issue:`763` +- Add a ``DerivedContextReference`` node that can be used by + extensions to get the current context and local variables such as + ``loop``. :issue:`860` +- Constant folding during compilation is applied to some node types + that were previously overlooked. :issue:`733` +- ``TemplateSyntaxError.source`` is not empty when raised from an + included template. :issue:`457` +- Passing an ``Undefined`` value to ``get_template`` (such as through + ``extends``, ``import``, or ``include``), raises an + ``UndefinedError`` consistently. ``select_template`` will show the + undefined message in the list of attempts rather than the empty + string. :issue:`1037` +- ``TemplateSyntaxError`` can be pickled. :pr:`1117` + + +Version 2.10.3 +-------------- + +Released 2019-10-04 + +- Fix a typo in Babel entry point in ``setup.py`` that was preventing + installation. + + +Version 2.10.2 +-------------- + +Released 2019-10-04 + +- Fix Python 3.7 deprecation warnings. +- Using ``range`` in the sandboxed environment uses ``xrange`` on + Python 2 to avoid memory use. :issue:`933` +- Use Python 3.7's better traceback support to avoid a core dump when + using debug builds of Python 3.7. :issue:`1050` + + +Version 2.10.1 +-------------- + +Released 2019-04-06 + +- ``SandboxedEnvironment`` securely handles ``str.format_map`` in + order to prevent code execution through untrusted format strings. + The sandbox already handled ``str.format``. + + +Version 2.10 +------------ + +Released 2017-11-08 + +- Added a new extension node called ``OverlayScope`` which can be used + to create an unoptimized scope that will look up all variables from + a derived context. +- Added an ``in`` test that works like the in operator. This can be + used in combination with ``reject`` and ``select``. +- Added ``previtem`` and ``nextitem`` to loop contexts, providing + access to the previous/next item in the loop. If such an item does + not exist, the value is undefined. +- Added ``changed(*values)`` to loop contexts, providing an easy way + of checking whether a value has changed since the last iteration (or + rather since the last call of the method) +- Added a ``namespace`` function that creates a special object which + allows attribute assignment using the ``set`` tag. This can be used + to carry data across scopes, e.g. from a loop body to code that + comes after the loop. +- Added a ``trimmed`` modifier to ``{% trans %}`` to strip linebreaks + and surrounding whitespace. Also added a new policy to enable this + for all ``trans`` blocks. +- The ``random`` filter is no longer incorrectly constant folded and + will produce a new random choice each time the template is rendered. + :pr:`478` +- Added a ``unique`` filter. :pr:`469` +- Added ``min`` and ``max`` filters. :pr:`475` +- Added tests for all comparison operators: ``eq``, ``ne``, ``lt``, + ``le``, ``gt``, ``ge``. :pr:`665` +- ``import`` statement cannot end with a trailing comma. :pr:`617`, + :pr:`618` +- ``indent`` filter will not indent blank lines by default. :pr:`685` +- Add ``reverse`` argument for ``dictsort`` filter. :pr:`692` +- Add a ``NativeEnvironment`` that renders templates to native Python + types instead of strings. :pr:`708` +- Added filter support to the block ``set`` tag. :pr:`489` +- ``tojson`` filter marks output as safe to match documented behavior. + :pr:`718` +- Resolved a bug where getting debug locals for tracebacks could + modify template context. +- Fixed a bug where having many ``{% elif ... %}`` blocks resulted in + a "too many levels of indentation" error. These blocks now compile + to native ``elif ..:`` instead of ``else: if ..:`` :issue:`759` + + +Version 2.9.6 +------------- + +Released 2017-04-03 + +- Fixed custom context behavior in fast resolve mode :issue:`675` + + +Version 2.9.5 +------------- + +Released 2017-01-28 + +- Restored the original repr of the internal ``_GroupTuple`` because + this caused issues with ansible and it was an unintended change. + :issue:`654` +- Added back support for custom contexts that override the old + ``resolve`` method since it was hard for people to spot that this + could cause a regression. +- Correctly use the buffer for the else block of for loops. This + caused invalid syntax errors to be caused on 2.x and completely + wrong behavior on Python 3 :issue:`669` +- Resolve an issue where the ``{% extends %}`` tag could not be used + with async environments. :issue:`668` +- Reduce memory footprint slightly by reducing our unicode database + dump we use for identifier matching on Python 3 :issue:`666` +- Fixed autoescaping not working for macros in async compilation mode. + :issue:`671` + + +Version 2.9.4 +------------- + +Released 2017-01-10 + +- Solved some warnings for string literals. :issue:`646` +- Increment the bytecode cache version which was not done due to an + oversight before. +- Corrected bad code generation and scoping for filtered loops. + :issue:`649` +- Resolved an issue where top-level output silencing after known + extend blocks could generate invalid code when blocks where + contained in if statements. :issue:`651` +- Made the ``truncate.leeway`` default configurable to improve + compatibility with older templates. + + +Version 2.9.3 +------------- + +Released 2017-01-08 + +- Restored the use of blocks in macros to the extend that was possible + before. On Python 3 it would render a generator repr instead of the + block contents. :issue:`645` +- Set a consistent behavior for assigning of variables in inner scopes + when the variable is also read from an outer scope. This now sets + the intended behavior in all situations however it does not restore + the old behavior where limited assignments to outer scopes was + possible. For more information and a discussion see :issue:`641` +- Resolved an issue where ``block scoped`` would not take advantage of + the new scoping rules. In some more exotic cases a variable + overriden in a local scope would not make it into a block. +- Change the code generation of the ``with`` statement to be in line + with the new scoping rules. This resolves some unlikely bugs in edge + cases. This also introduces a new internal ``With`` node that can be + used by extensions. + + +Version 2.9.2 +------------- + +Released 2017-01-08 + +- Fixed a regression that caused for loops to not be able to use the + same variable for the target as well as source iterator. + :issue:`640` +- Add support for a previously unknown behavior of macros. It used to + be possible in some circumstances to explicitly provide a caller + argument to macros. While badly buggy and unintended it turns out + that this is a common case that gets copy pasted around. To not + completely break backwards compatibility with the most common cases + it's now possible to provide an explicit keyword argument for caller + if it's given an explicit default. :issue:`642` + + +Version 2.9.1 +------------- + +Released 2017-01-07 + +- Resolved a regression with call block scoping for macros. Nested + caller blocks that used the same identifiers as outer macros could + refer to the wrong variable incorrectly. + + +Version 2.9 +----------- + +Released 2017-01-07, codename Derivation + +- Change cache key definition in environment. This fixes a performance + regression introduced in 2.8. +- Added support for ``generator_stop`` on supported Python versions + (Python 3.5 and later) +- Corrected a long standing issue with operator precedence of math + operations not being what was expected. +- Added support for Python 3.6 async iterators through a new async + mode. +- Added policies for filter defaults and similar things. +- Urlize now sets "rel noopener" by default. +- Support attribute fallback for old-style classes in 2.x. +- Support toplevel set statements in extend situations. +- Restored behavior of Cycler for Python 3 users. +- Subtraction now follows the same behavior as other operators on + undefined values. +- ``map`` and friends will now give better error messages if you + forgot to quote the parameter. +- Depend on MarkupSafe 0.23 or higher. +- Improved the ``truncate`` filter to support better truncation in + case the string is barely truncated at all. +- Change the logic for macro autoescaping to be based on the runtime + autoescaping information at call time instead of macro define time. +- Ported a modified version of the ``tojson`` filter from Flask to + Jinja and hooked it up with the new policy framework. +- Block sets are now marked ``safe`` by default. +- On Python 2 the asciification of ASCII strings can now be disabled + with the ``compiler.ascii_str`` policy. +- Tests now no longer accept an arbitrary expression as first argument + but a restricted one. This means that you can now properly use + multiple tests in one expression without extra parentheses. In + particular you can now write ``foo is divisibleby 2 or foo is + divisibleby 3`` as you would expect. +- Greatly changed the scoping system to be more consistent with what + template designers and developers expect. There is now no more magic + difference between the different include and import constructs. + Context is now always propagated the same way. The only remaining + differences is the defaults for ``with context`` and ``without + context``. +- The ``with`` and ``autoescape`` tags are now built-in. +- Added the new ``select_autoescape`` function which helps configuring + better autoescaping easier. +- Fixed a runtime error in the sandbox when attributes of async + generators were accessed. + + +Version 2.8.1 +------------- + +Released 2016-12-29 + +- Fixed the ``for_qs`` flag for ``urlencode``. +- Fixed regression when applying ``int`` to non-string values. +- SECURITY: if the sandbox mode is used format expressions are now + sandboxed with the same rules as in Jinja. This solves various + information leakage problems that can occur with format strings. + + +Version 2.8 +----------- + +Released 2015-07-26, codename Replacement + +- Added ``target`` parameter to urlize function. +- Added support for ``followsymlinks`` to the file system loader. +- The truncate filter now counts the length. +- Added equalto filter that helps with select filters. +- Changed cache keys to use absolute file names if available instead + of load names. +- Fixed loop length calculation for some iterators. +- Changed how Jinja enforces strings to be native strings in Python 2 + to work when people break their default encoding. +- Added ``make_logging_undefined`` which returns an undefined + object that logs failures into a logger. +- If unmarshalling of cached data fails the template will be reloaded + now. +- Implemented a block ``set`` tag. +- Default cache size was increased to 400 from a low 50. +- Fixed ``is number`` test to accept long integers in all Python + versions. +- Changed ``is number`` to accept Decimal as a number. +- Added a check for default arguments followed by non-default + arguments. This change makes ``{% macro m(x, y=1, z) %}`` a syntax + error. The previous behavior for this code was broken anyway + (resulting in the default value being applied to ``y``). +- Add ability to use custom subclasses of + ``jinja2.compiler.CodeGenerator`` and ``jinja2.runtime.Context`` by + adding two new attributes to the environment + (``code_generator_class`` and ``context_class``). :pr:`404` +- Added support for context/environment/evalctx decorator functions on + the finalize callback of the environment. +- Escape query strings for urlencode properly. Previously slashes were + not escaped in that place. +- Add 'base' parameter to 'int' filter. + + +Version 2.7.3 +------------- + +Released 2014-06-06 + +- Security issue: Corrected the security fix for the cache folder. + This fix was provided by RedHat. + + +Version 2.7.2 +------------- + +Released 2014-01-10 + +- Prefix loader was not forwarding the locals properly to inner + loaders. This is now fixed. +- Security issue: Changed the default folder for the filesystem cache + to be user specific and read and write protected on UNIX systems. + See `Debian bug 734747`_ for more information. + +.. _Debian bug 734747: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=734747 + + +Version 2.7.1 +------------- + +Released 2013-08-07 + +- Fixed a bug with ``call_filter`` not working properly on environment + and context filters. +- Fixed lack of Python 3 support for bytecode caches. +- Reverted support for defining blocks in included templates as this + broke existing templates for users. +- Fixed some warnings with hashing of undefineds and nodes if Python + is run with warnings for Python 3. +- Added support for properly hashing undefined objects. +- Fixed a bug with the title filter not working on already uppercase + strings. + + +Version 2.7 +----------- + +Released 2013-05-20, codename Translation + +- Choice and prefix loaders now dispatch source and template lookup + separately in order to work in combination with module loaders as + advertised. +- Fixed filesizeformat. +- Added a non-silent option for babel extraction. +- Added ``urlencode`` filter that automatically quotes values for URL + safe usage with utf-8 as only supported encoding. If applications + want to change this encoding they can override the filter. +- Added ``keep-trailing-newline`` configuration to environments and + templates to optionally preserve the final trailing newline. +- Accessing ``last`` on the loop context no longer causes the iterator + to be consumed into a list. +- Python requirement changed: 2.6, 2.7 or >= 3.3 are required now, + supported by same source code, using the "six" compatibility + library. +- Allow ``contextfunction`` and other decorators to be applied to + ``__call__``. +- Added support for changing from newline to different signs in the + ``wordwrap`` filter. +- Added support for ignoring memcache errors silently. +- Added support for keeping the trailing newline in templates. +- Added finer grained support for stripping whitespace on the left + side of blocks. +- Added ``map``, ``select``, ``reject``, ``selectattr`` and + ``rejectattr`` filters. +- Added support for ``loop.depth`` to figure out how deep inside a + recursive loop the code is. +- Disabled py_compile for pypy and python 3. + + +Version 2.6 +----------- + +Released 2011-07-24, codename Convolution + +- Internal attributes now raise an internal attribute error now + instead of returning an undefined. This fixes problems when passing + undefined objects to Python semantics expecting APIs. +- Traceback support now works properly for PyPy. (Tested with 1.4) +- Implemented operator intercepting for sandboxed environments. This + allows application developers to disable builtin operators for + better security. (For instance limit the mathematical operators to + actual integers instead of longs) +- Groupby filter now supports dotted notation for grouping by + attributes of attributes. +- Scoped blocks now properly treat toplevel assignments and imports. + Previously an import suddenly "disappeared" in a scoped block. +- Automatically detect newer Python interpreter versions before + loading code from bytecode caches to prevent segfaults on invalid + opcodes. The segfault in earlier Jinja versions here was not a + Jinja bug but a limitation in the underlying Python interpreter. If + you notice Jinja segfaulting in earlier versions after an upgrade + of the Python interpreter you don't have to upgrade, it's enough to + flush the bytecode cache. This just no longer makes this necessary, + Jinja will automatically detect these cases now. +- The sum filter can now sum up values by attribute. This is a + backwards incompatible change. The argument to the filter previously + was the optional starting index which defaults to zero. This now + became the second argument to the function because it's rarely used. +- Like sum, sort now also makes it possible to order items by + attribute. +- Like sum and sort, join now also is able to join attributes of + objects as string. +- The internal eval context now has a reference to the environment. +- Added a mapping test to see if an object is a dict or an object with + a similar interface. + + +Version 2.5.5 +------------- + +Released 2010-10-18 + +- Built documentation is no longer part of release. + + +Version 2.5.4 +------------- + +Released 2010-10-17 + +- Fixed extensions not loading properly with overlays. +- Work around a bug in cpython for the debugger that causes segfaults + on 64bit big-endian architectures. + + +Version 2.5.3 +------------- + +Released 2010-10-17 + +- Fixed an operator precedence error introduced in 2.5.2. Statements + like "-foo.bar" had their implicit parentheses applied around the + first part of the expression ("(-foo).bar") instead of the more + correct "-(foo.bar)". + + +Version 2.5.2 +------------- + +Released 2010-08-18 + +- Improved setup.py script to better work with assumptions people + might still have from it (``--with-speedups``). +- Fixed a packaging error that excluded the new debug support. + + +Version 2.5.1 +------------- + +Released 2010-08-17 + +- StopIteration exceptions raised by functions called from templates + are now intercepted and converted to undefineds. This solves a lot + of debugging grief. (StopIteration is used internally to abort + template execution) +- Improved performance of macro calls slightly. +- Babel extraction can now properly extract newstyle gettext calls. +- Using the variable ``num`` in newstyle gettext for something else + than the pluralize count will no longer raise a :exc:`KeyError`. +- Removed builtin markup class and switched to markupsafe. For + backwards compatibility the pure Python implementation still exists + but is pulled from markupsafe by the Jinja developers. The debug + support went into a separate feature called "debugsupport" and is + disabled by default because it is only relevant for Python 2.4 +- Fixed an issue with unary operators having the wrong precedence. + + +Version 2.5 +----------- + +Released 2010-05-29, codename Incoherence + +- Improved the sort filter (should have worked like this for a long + time) by adding support for case insensitive searches. +- Fixed a bug for getattribute constant folding. +- Support for newstyle gettext translations which result in a nicer + in-template user interface and more consistent catalogs. +- It's now possible to register extensions after an environment was + created. + + +Version 2.4.1 +------------- + +Released 2010-04-20 + +- Fixed an error reporting bug for undefined. + + +Version 2.4 +----------- + +Released 2010-04-13, codename Correlation + +- The environment template loading functions now transparently pass + through a template object if it was passed to it. This makes it + possible to import or extend from a template object that was passed + to the template. +- Added a ``ModuleLoader`` that can load templates from + precompiled sources. The environment now features a method to + compile the templates from a configured loader into a zip file or + folder. +- The _speedups C extension now supports Python 3. +- Added support for autoescaping toggling sections and support for + evaluation contexts. +- Extensions have a priority now. + + +Version 2.3.1 +------------- + +Released 2010-02-19 + +- Fixed an error reporting bug on all python versions +- Fixed an error reporting bug on Python 2.4 + + +Version 2.3 +----------- + +Released 2010-02-10, codename 3000 Pythons + +- Fixes issue with code generator that causes unbound variables to be + generated if set was used in if-blocks and other small identifier + problems. +- Include tags are now able to select between multiple templates and + take the first that exists, if a list of templates is given. +- Fixed a problem with having call blocks in outer scopes that have an + argument that is also used as local variable in an inner frame + :issue:`360`. +- Greatly improved error message reporting :pr:`339` +- Implicit tuple expressions can no longer be totally empty. This + change makes ``{% if %}`` a syntax error now. :issue:`364` +- Added support for translator comments if extracted via babel. +- Added with-statement extension. +- Experimental Python 3 support. + + +Version 2.2.1 +------------- + +Released 2009-09-14 + +- Fixes some smaller problems for Jinja on Jython. + + +Version 2.2 +----------- + +Released 2009-09-13, codename Kong + +- Include statements can now be marked with ``ignore missing`` to skip + non existing templates. +- Priority of ``not`` raised. It's now possible to write ``not foo in + bar`` as an alias to ``foo not in bar`` like in python. Previously + the grammar required parentheses (``not (foo in bar)``) which was + odd. +- Fixed a bug that caused syntax errors when defining macros or using + the ``{% call %}`` tag inside loops. +- Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible. +- Made it possible to refer to names from outer scopes in included + templates that were unused in the callers frame :issue:`327` +- Fixed a bug that caused internal errors if names where used as + iteration variable and regular variable *after* the loop if that + variable was unused *before* the loop. :pr:`331` +- Added support for optional ``scoped`` modifier to blocks. +- Added support for line-comments. +- Added the ``meta`` module. +- Renamed (undocumented) attribute "overlay" to "overlayed" on the + environment because it was clashing with a method of the same name. +- Speedup extension is now disabled by default. + + +Version 2.1.1 +------------- + +Released 2008-12-25 + +- Fixed a translation error caused by looping over empty recursive + loops. + + +Version 2.1 +----------- + +Released 2008-11-23, codename Yasuzō + +- Fixed a bug with nested loops and the special loop variable. Before + the change an inner loop overwrote the loop variable from the outer + one after iteration. +- Fixed a bug with the i18n extension that caused the explicit + pluralization block to look up the wrong variable. +- Fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` + impossible. +- Index based subscribing of variables with a constant value returns + an undefined object now instead of raising an index error. This was + a bug caused by eager optimizing. +- The i18n extension looks up ``foo.ugettext`` now followed by + ``foo.gettext`` if an translations object is installed. This makes + dealing with custom translations classes easier. +- Fixed a confusing behavior with conditional extending. loops were + partially executed under some conditions even though they were not + part of a visible area. +- Added ``sort`` filter that works like ``dictsort`` but for arbitrary + sequences. +- Fixed a bug with empty statements in macros. +- Implemented a bytecode cache system. +- The template context is now weakref-able +- Inclusions and imports "with context" forward all variables now, not + only the initial context. +- Added a cycle helper called ``cycler``. +- Added a joining helper called ``joiner``. +- Added a ``compile_expression`` method to the environment that allows + compiling of Jinja expressions into callable Python objects. +- Fixed an escaping bug in urlize + + +Version 2.0 +----------- + +Released 2008-07-17, codename Jinjavitus + +- The subscribing of objects (looking up attributes and items) changed + from slightly. It's now possible to give attributes or items a + higher priority by either using dot-notation lookup or the bracket + syntax. This also changed the AST slightly. ``Subscript`` is gone + and was replaced with ``Getitem`` and ``Getattr``. +- Added support for preprocessing and token stream filtering for + extensions. This would allow extensions to allow simplified gettext + calls in template data and something similar. +- Added ``TemplateStream.dump``. +- Added missing support for implicit string literal concatenation. + ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}`` +- ``else`` is optional for conditional expressions. If not given it + evaluates to ``false``. +- Improved error reporting for undefined values by providing a + position. +- ``filesizeformat`` filter uses decimal prefixes now per default and + can be set to binary mode with the second parameter. +- Fixed bug in finalizer + + +Version 2.0rc1 +-------------- + +Released 2008-06-09 + +- First release of Jinja 2. |
