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.
20 - Fixed a translation error caused by looping over empty recursive loops.
24 (codename Yasuzō, released on November 23rd 2008)
26 - fixed a bug with nested loops and the special loop variable. Before the
27 change an inner loop overwrote the loop variable from the outer one after
30 - fixed a bug with the i18n extension that caused the explicit pluralization
31 block to look up the wrong variable.
33 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
35 - index based subscribing of variables with a constant value returns an
36 undefined object now instead of raising an index error. This was a bug
37 caused by eager optimizing.
39 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
40 if an translations object is installed. This makes dealing with custom
41 translations classes easier.
43 - fixed a confusing behavior with conditional extending. loops were partially
44 executed under some conditions even though they were not part of a visible
47 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
49 - fixed a bug with empty statements in macros.
51 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
53 - the template context is now weakref-able
55 - inclusions and imports "with context" forward all variables now, not only
58 - added a cycle helper called `cycler`.
60 - added a joining helper called `joiner`.
62 - added a `compile_expression` method to the environment that allows compiling
63 of Jinja expressions into callable Python objects.
65 - fixed an escaping bug in urlize
69 (codename jinjavitus, released on July 17th 2008)
71 - the subscribing of objects (looking up attributes and items) changed from
72 slightly. It's now possible to give attributes or items a higher priority
73 by either using dot-notation lookup or the bracket syntax. This also
74 changed the AST slightly. `Subscript` is gone and was replaced with
75 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
77 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
79 - added support for preprocessing and token stream filtering for extensions.
80 This would allow extensions to allow simplified gettext calls in template
81 data and something similar.
83 - added :meth:`jinja2.environment.TemplateStream.dump`.
85 - added missing support for implicit string literal concatenation.
86 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
88 - `else` is optional for conditional expressions. If not given it evaluates
91 - improved error reporting for undefined values by providing a position.
93 - `filesizeformat` filter uses decimal prefixes now per default and can be
94 set to binary mode with the second parameter.
96 - fixed bug in finalizer
100 (no codename, released on June 9th 2008)
102 - first release of Jinja2
