-Jinja Changelog
+Jinja2 Changelog
 ===============
 
-Version 1.3
+Version 2.0
 -----------
-(codename to be selected, release around February 2007)
+(codename to be selected, release around July 2008)
 
-Version 1.2
------------
-(codename to be hatsuyuki, released Nov 17th 2007)
-
-.. admonition:: Backwards Incompatible Changes
-
-    - `call` is a keyword now
-    - the internal parser AST changed
-    - `extends` must be the first tag in a template
-    - the tuple literal yields tuples now, instead of lists.
-
-- environments now have a `translator_factory` parameter that allows
-  to change the translator without subclassing the environment.
-
-- fixed bug in buffet plugin regarding the package loader
-
-- once again improved debugger.
-
-- added `groupby` filter.
-
-- added `sameas` test function.
-
-- standalone parser. Jinja does not use the python parser any more and will
-  continue having the same semantics in any future python versions. This
-  was done in order to simplify updating Jinja to 2.6 and 3.0 and to support
-  non python syntax.
-
-- added support for ``expr1 if test else expr2`` (conditional expressions)
-
-- ``foo.0`` as alias for ``foo[0]`` is possible now. This is mainly for
-  django compatibility.
-
-- the filter operators has a much higher priority now which makes it
-  possible to do ``foo|filter + bar|filter``.
-
-- new AST. the return value of `Environment.parse` is now a Jinja AST and not
-  a Jinja-Python AST. This is also the only backwards incompatible change but
-  should not affect many users because this feature is more or less
-  undocumented and has few use cases.
-
-- tuple syntax returns tuples now and not lists any more.
-
-- the print directive and ``{{ variable }}`` syntax now accepts and implicit
-  tuple like the `for` and `cycle` tags. (``{{ 1, 2 }}`` is an implicit alias
-  for ``{{ (1, 2) }}` like ``{% for a, b in seq %}`` is for
-  ``{% for (a, b) in seq %}``.
-
-- tests called with *one* parameter don't need parentheses. This gives a more
-  natural syntax for the `sameas` test and some others:
-  ``{{ foo is sameas bar }}`` instead of ``{{ foo is sameas(bar) }}``. If you
-  however want to pass more than one argument you have to use parentheses
-  because ``{{ foo is sometest bar, baz }}`` is handled as
-  ``{{ (foo is sometest(bar), baz) }}``, so as tuple expression.
-
-- removed support for octal character definitions in strings such as
-  ``'\14'``, use ``'\x0c'`` now.
-
-- added regular expression literal. ``@/expr/flags`` equals
-  ``re.compile(r'(?flags)expr')``. This is useful for the `matching` test and
-  probably some others.
-
-- added set literal. We do not use python3's {1, 2} syntax because
-  this conflicts with the dict literal. To be compatible with the regex
-  literal we use ``@(1, 2)`` instead.
-
-- fixed bug in `get_attribute` that disallowed retreiving attributes of objects
-  without a `__class__` such as `_sre.SRE_Pattern`.
-
-- addded `django.contrib.jinja` which provides advanced support for django.
-  (thanks Bryan McLemore)
-
-- debugger is now able to rewrite the whole traceback, not only the first
-  frame. (requires the optional debugger c module which is compiled
-  automatically on installation if possible)
-
-- if the set that is postfixed with a bang (!) it acts like the python 3
-  "nonlocal" keyword. This means that you can now override variables
-  defined in the outer scope from within a loop.
-
-- ``foo ~ bar`` is now a simpler alternative to ``foo|string + bar|string``
-
-- `PackageLoader` can now work without pkg_resources too
-
-- added `getattribute` and `getitem` filter.
-
-- added support for the `pretty` library.
-
-- changed the way the `MemcachedLoaderMixin` creates the class so that it's
-  possible to hook your own client in.
-
-
-Version 1.1
------------
-(codename: sinka, released Jun 1, 2007)
-
-- blocks now support ``{{ super() }}`` to render the parent output.
-
-- debugging system improved, smaller filesize for the cached files.
-  Debugging works now well for any module using linecache.
-
-- ``{{ debug() }}`` can now be used to get a list of filters and
-  tags.
-
-- 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.
-
-- it's now possible to configure the variable blocks to look the
-  same as the block delimiters. Thus you can set the syntax to something
-  like ``{ / }`` for both blocks and variables.
-
-- added whitespace management system for the template designer.
-
-- some small bugfixes.
-
-- improved security system regarding function calls and variable
-  assignment in for loops.
-
-- added `lipsum` function to generate random text.
-
-- strings without unicode characters are processed as binary strings now
-  to workaround problems with `datetime.strftime` which only accepts
-  binary strings.
-
-- it's now possible to use newlines in string literals
-
-- developer friendly traceback is now toggleable
-
-- the variable failure is now pluggable by replacing the undefined
-  singleton for an environment instance
-
-- fixed issue with old-style classes not implementing `__getitem__`
-  (thanks to Axel Böhm for discovering that bug)
-
-- added a bunch of new docstrings to the Jinja classes. Makes fun now to
-  use pydoc :-)
-
-- fixed severe memcaching bug. Formerly it wasn't possible to use memcaching
-  without enabling disk cache.
-
-- fixed a bug that allowed users to override the special names `_`, `true` etc.
-
-- added `batch` and `slice` filters for batching or slicing sequences
-
-- added `sum`, `abs`, `round` and `sort` filters. This fixes #238
-
-- added `striptags` and `xmlattr` filters for easier SGML/XML processing
-
-- 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 %}``.
-
-- reimplemented Buffet plugin so that it works at least for pylons
-
-- added `Environment.get_translations_for_string`
-
-- fixed a bug in the parser that didn't unescape keyword arguments. (thanks
-  to Alexey Melchakov for reporting)
-
-- You can now use the environment to just tokenize a template. This can
-  be useful for syntax highlighting or other purposes.
-
-- added optional C-implementation of the context baseclass.
-
-- 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 %}``.
-
-- additional macro arguments now end up in `varargs`.
-
-- implemented the `{% call %}` block. `call` and `endcall` can still be used
-  as identifiers until Jinja 1.3
-
-- it's now possible to stream templates.
-
-- fixed a corner case when defining a block inside of a condition
-
-- the cached loader mixin is now able to cache multiple templates from
-  different loaders in the same cache folder.
-
-- Translatable strings returned by ``_()`` will leave their string formatting
-  signs untouched. Thanks to Stefan Ebner for reporting.
-
-- ``{% block name "data" %}`` is now an alias for
-  ``{% block name %}data{% endblock %}``. Note that the second argument can
-  be an expression. As soon as you specify an expression as second argument
-  the closing tag has to be omitted.
-
-- It's now possible to iterate over iterators additionally to sequences.
-  If the iterator is inifite it will crash however, so makes sure you don't
-  pass something like that to a template!
-
-- added `rendetemplate` to render included templates in an isolated
-  environment and get the outout back.
-
-- added `simplefilter` decorator.
-
-- improved ChoiceLoader error reporting (thanks to Bryan McLemore)
-
-- fixed extended slicing
-
-- reworked loader layer. All the cached loaders now have "private" non cached
-  baseclasses so that you can easily mix your own caching layers in.
-
-- added `MemcachedLoaderMixin` and `MemcachedFileSystemLoader` contributed
-  by Bryan McLemore.
