+Jinja2 Changelog
+================
-Version 1.1
+Version 2.4
-----------
(codename to be selected, release date unknown)
-- blocks now support ``{{ super() }}`` to render the parent output.
+- 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 :class:`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.
-- debugging system improved, smaller filesize for the cached files.
- Debugging works now well for any module using linecache.
+- the _speedups C extension now supports Python 3.
-- ``{{ debug() }}`` can now be used to get a list of filters and
- tags.
+Version 2.3.1
+-------------
+(bugfix release, released on February 19th 2010)
-- the template lexer keeps not track of brace, parenthesis and
- bracket balance in order to not break variable tags apart if they
- are configured to look like this: ``${expr}``. This also fixes
- the problem with nested dicts in variable expressions.
+- fixed an error reporting bug on all python versions
+- fixed an error reporting bug on Python 2.4
-- added whitespace management system for the template designer.
-
-- some small bugfixes.
+Version 2.3
+-----------
+(3000 Pythons, released on February 10th 2010)
+
+- 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 (#360).
+- greatly improved error message reporting (#339)
+- implicit tuple expressions can no longer be totally empty.
+ This change makes ``{% if %}...{% endif %}`` a syntax error
+ now. (#364)
+- added support for translator comments if extracted via babel.
+- added with-statement extension.
+- experimental Python 3 support.
+
+Version 2.2.1
+-------------
+(bugfix release, released on September 14th 2009)
+
+- fixes some smaller problems for Jinja2 on Jython.
+
+Version 2.2
+-----------
+(codename Kong, released on September 13th 2009)
+
+- 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 (#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. (#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
+-------------
+(Bugfix release)
+
+- Fixed a translation error caused by looping over empty recursive loops.
+
+Version 2.1
+-----------
+(codename Yasuzō, released on November 23rd 2008)
-- improved security system regarding function calls and variable
- assignment in for loops.
+- 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.
-- added `lipsum` function to generate random text.
+- fixed a bug with the i18n extension that caused the explicit pluralization
+ block to look up the wrong variable.
-- strings without unicode characters are processed as binary strings now
- to workaround problems with `datetime.strftime` which only accepts
- binary strings.
+- fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
-- it's now possible to use newlines in string literals
+- 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.
-- developer friendly traceback is now toggleable
+- 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.
-- the variable failure is now pluggable by replacing the undefined
- singleton for an environment instance
+- fixed a confusing behavior with conditional extending. loops were partially
+ executed under some conditions even though they were not part of a visible
+ area.
-- fixed issue with old-style classes not implementing `__getitem__`
- (thanks to Axel Böhm for discovering that bug)
+- added `sort` filter that works like `dictsort` but for arbitrary sequences.
-- added a bunch of new docstrings to the Jinja classes. Makes fun now to
- use pydoc :-)
+- fixed a bug with empty statements in macros.
-- fixed severe memcaching bug. Formerly it wasn't possible to use memcaching
- without enabling disk cache.
+- implemented a bytecode cache system. (:ref:`bytecode-cache`)
-- fixed a bug that allowed users to override the special names `_`, `true` etc.
+- the template context is now weakref-able
-- added `batch` and `slice` filters for batching or slicing sequences
+- inclusions and imports "with context" forward all variables now, not only
+ the initial context.
-- added `sum`, `abs` and `round` filters. This fixes #238
+- added a cycle helper called `cycler`.
-- added `striptags` and `xmlattr` filters for easier SGML/XML processing
+- added a joining helper called `joiner`.
-- the trans tag does not need explicit naming for variables with the same
- name any more. You can now use ``{% trans foo %}`` instead of the verbose
- version ``{% trans foo=foo %}``.
+- added a `compile_expression` method to the environment that allows compiling
+ of Jinja expressions into callable Python objects.
-- reimplemented Buffet plugin so that it works at least for pylons
+- fixed an escaping bug in urlize
-- added `Environment.get_translations_for_string`
+Version 2.0
+-----------
+(codename jinjavitus, released on July 17th 2008)
-- fixed a bug in the parser that didn't unescape keyword arguments. (thanks
- to Alexey Melchakov for reporting)
+- 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
+ :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
-- You can now use the environment to just tokenize a template. This can
- be useful for syntax highlighting or other purposes.
+ For more information see :ref:`the implementation details <notes-on-subscriptions>`.
-- added optional C-implementation of the context baseclass.
+- 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.
-- you can now use optional parentheses around macro defintions. Thus it's
- possible to write ``{% macro foo(a, b, c) %}`` instead of ``{% macro
- foo a, b, c %}``.
+- added :meth:`jinja2.environment.TemplateStream.dump`.
-- additional macro arguments now end up in `varargs`.
+- added missing support for implicit string literal concatenation.
+ ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
-- implemented `{% call %}` - unsure if this makes it into the final release.
+- `else` is optional for conditional expressions. If not given it evaluates
+ to `false`.
-- it's not possible to stream templates.
+- improved error reporting for undefined values by providing a position.
-- fixed a corner case when defining a block inside of a condition
+- `filesizeformat` filter uses decimal prefixes now per default and can be
+ set to binary mode with the second parameter.
+- fixed bug in finalizer
