6 (codename to be selected, release date will be February 9th 2010)
8 - fixes issue with code generator that causes unbound variables
9 to be generated if set was used in if-blocks and other small
11 - include tags are now able to select between multiple templates
12 and take the first that exists, if a list of templates is
14 - fixed a problem with having call blocks in outer scopes that
15 have an argument that is also used as local variable in an
17 - greatly improved error message reporting (#339)
18 - implicit tuple expressions can no longer be totally empty.
19 This change makes ``{% if %}...{% endif %}`` a syntax error
21 - added support for translator comments if extracted via babel.
25 (bugfix release, released on September 14th 2009)
27 - fixes some smaller problems for Jinja2 on Jython.
31 (codename Kong, released on September 13th 2009)
33 - Include statements can now be marked with ``ignore missing`` to skip
34 non existing templates.
35 - Priority of `not` raised. It's now possible to write `not foo in bar`
36 as an alias to `foo not in bar` like in python. Previously the grammar
37 required parentheses (`not (foo in bar)`) which was odd.
38 - Fixed a bug that caused syntax errors when defining macros or using the
39 `{% call %}` tag inside loops.
40 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
41 - Made it possible to refer to names from outer scopes in included templates
42 that were unused in the callers frame (#327)
43 - Fixed a bug that caused internal errors if names where used as iteration
44 variable and regular variable *after* the loop if that variable was unused
45 *before* the loop. (#331)
46 - Added support for optional `scoped` modifier to blocks.
47 - Added support for line-comments.
48 - Added the `meta` module.
49 - Renamed (undocumented) attribute "overlay" to "overlayed" on the
50 environment because it was clashing with a method of the same name.
51 - speedup extension is now disabled by default.
57 - Fixed a translation error caused by looping over empty recursive loops.
61 (codename Yasuzō, released on November 23rd 2008)
63 - fixed a bug with nested loops and the special loop variable. Before the
64 change an inner loop overwrote the loop variable from the outer one after
67 - fixed a bug with the i18n extension that caused the explicit pluralization
68 block to look up the wrong variable.
70 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
72 - index based subscribing of variables with a constant value returns an
73 undefined object now instead of raising an index error. This was a bug
74 caused by eager optimizing.
76 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
77 if an translations object is installed. This makes dealing with custom
78 translations classes easier.
80 - fixed a confusing behavior with conditional extending. loops were partially
81 executed under some conditions even though they were not part of a visible
84 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
86 - fixed a bug with empty statements in macros.
88 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
90 - the template context is now weakref-able
92 - inclusions and imports "with context" forward all variables now, not only
95 - added a cycle helper called `cycler`.
97 - added a joining helper called `joiner`.
99 - added a `compile_expression` method to the environment that allows compiling
100 of Jinja expressions into callable Python objects.
102 - fixed an escaping bug in urlize
106 (codename jinjavitus, released on July 17th 2008)
108 - the subscribing of objects (looking up attributes and items) changed from
109 slightly. It's now possible to give attributes or items a higher priority
110 by either using dot-notation lookup or the bracket syntax. This also
111 changed the AST slightly. `Subscript` is gone and was replaced with
112 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
114 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
116 - added support for preprocessing and token stream filtering for extensions.
117 This would allow extensions to allow simplified gettext calls in template
118 data and something similar.
120 - added :meth:`jinja2.environment.TemplateStream.dump`.
122 - added missing support for implicit string literal concatenation.
123 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
125 - `else` is optional for conditional expressions. If not given it evaluates
128 - improved error reporting for undefined values by providing a position.
130 - `filesizeformat` filter uses decimal prefixes now per default and can be
131 set to binary mode with the second parameter.
133 - fixed bug in finalizer
137 (no codename, released on June 9th 2008)
139 - first release of Jinja2
