6 (codename unknown, release date yet unknown)
8 - Include statements can now be marked with ``ignore missing`` to skip
9 non existing templates.
10 - Priority of `not` raised. It's now possible to write `not foo in bar`
11 as an alias to `foo not in bar` like in python. Previously the grammar
12 required parentheses (`not (foo in bar)`) which was odd.
13 - Fixed a bug that caused syntax errors when defining macros or using the
14 `{% call %}` tag inside loops.
15 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
16 - Made it possible to refer to names from outer scopes in included templates
17 that were unused in the callers frame (#327)
23 - Fixed a translation error caused by looping over empty recursive loops.
27 (codename Yasuzō, released on November 23rd 2008)
29 - fixed a bug with nested loops and the special loop variable. Before the
30 change an inner loop overwrote the loop variable from the outer one after
33 - fixed a bug with the i18n extension that caused the explicit pluralization
34 block to look up the wrong variable.
36 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
38 - index based subscribing of variables with a constant value returns an
39 undefined object now instead of raising an index error. This was a bug
40 caused by eager optimizing.
42 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
43 if an translations object is installed. This makes dealing with custom
44 translations classes easier.
46 - fixed a confusing behavior with conditional extending. loops were partially
47 executed under some conditions even though they were not part of a visible
50 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
52 - fixed a bug with empty statements in macros.
54 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
56 - the template context is now weakref-able
58 - inclusions and imports "with context" forward all variables now, not only
61 - added a cycle helper called `cycler`.
63 - added a joining helper called `joiner`.
65 - added a `compile_expression` method to the environment that allows compiling
66 of Jinja expressions into callable Python objects.
68 - fixed an escaping bug in urlize
72 (codename jinjavitus, released on July 17th 2008)
74 - the subscribing of objects (looking up attributes and items) changed from
75 slightly. It's now possible to give attributes or items a higher priority
76 by either using dot-notation lookup or the bracket syntax. This also
77 changed the AST slightly. `Subscript` is gone and was replaced with
78 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
80 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
82 - added support for preprocessing and token stream filtering for extensions.
83 This would allow extensions to allow simplified gettext calls in template
84 data and something similar.
86 - added :meth:`jinja2.environment.TemplateStream.dump`.
88 - added missing support for implicit string literal concatenation.
89 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
91 - `else` is optional for conditional expressions. If not given it evaluates
94 - improved error reporting for undefined values by providing a position.
96 - `filesizeformat` filter uses decimal prefixes now per default and can be
97 set to binary mode with the second parameter.
99 - fixed bug in finalizer
103 (no codename, released on June 9th 2008)
105 - first release of Jinja2
