6 (codename to be selected, release date unknown)
8 - the environment template loading functions now transparently
9 pass through a template object if it was passed to it. This
10 makes it possible to import or extend from a template object
11 that was passed to the template.
15 (3000 Pythons, released on February 10th 2010)
17 - fixes issue with code generator that causes unbound variables
18 to be generated if set was used in if-blocks and other small
20 - include tags are now able to select between multiple templates
21 and take the first that exists, if a list of templates is
23 - fixed a problem with having call blocks in outer scopes that
24 have an argument that is also used as local variable in an
26 - greatly improved error message reporting (#339)
27 - implicit tuple expressions can no longer be totally empty.
28 This change makes ``{% if %}...{% endif %}`` a syntax error
30 - added support for translator comments if extracted via babel.
31 - added with-statement extension.
32 - experimental Python 3 support.
36 (bugfix release, released on September 14th 2009)
38 - fixes some smaller problems for Jinja2 on Jython.
42 (codename Kong, released on September 13th 2009)
44 - Include statements can now be marked with ``ignore missing`` to skip
45 non existing templates.
46 - Priority of `not` raised. It's now possible to write `not foo in bar`
47 as an alias to `foo not in bar` like in python. Previously the grammar
48 required parentheses (`not (foo in bar)`) which was odd.
49 - Fixed a bug that caused syntax errors when defining macros or using the
50 `{% call %}` tag inside loops.
51 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
52 - Made it possible to refer to names from outer scopes in included templates
53 that were unused in the callers frame (#327)
54 - Fixed a bug that caused internal errors if names where used as iteration
55 variable and regular variable *after* the loop if that variable was unused
56 *before* the loop. (#331)
57 - Added support for optional `scoped` modifier to blocks.
58 - Added support for line-comments.
59 - Added the `meta` module.
60 - Renamed (undocumented) attribute "overlay" to "overlayed" on the
61 environment because it was clashing with a method of the same name.
62 - speedup extension is now disabled by default.
68 - Fixed a translation error caused by looping over empty recursive loops.
72 (codename Yasuzō, released on November 23rd 2008)
74 - fixed a bug with nested loops and the special loop variable. Before the
75 change an inner loop overwrote the loop variable from the outer one after
78 - fixed a bug with the i18n extension that caused the explicit pluralization
79 block to look up the wrong variable.
81 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
83 - index based subscribing of variables with a constant value returns an
84 undefined object now instead of raising an index error. This was a bug
85 caused by eager optimizing.
87 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
88 if an translations object is installed. This makes dealing with custom
89 translations classes easier.
91 - fixed a confusing behavior with conditional extending. loops were partially
92 executed under some conditions even though they were not part of a visible
95 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
97 - fixed a bug with empty statements in macros.
99 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
101 - the template context is now weakref-able
103 - inclusions and imports "with context" forward all variables now, not only
106 - added a cycle helper called `cycler`.
108 - added a joining helper called `joiner`.
110 - added a `compile_expression` method to the environment that allows compiling
111 of Jinja expressions into callable Python objects.
113 - fixed an escaping bug in urlize
117 (codename jinjavitus, released on July 17th 2008)
119 - the subscribing of objects (looking up attributes and items) changed from
120 slightly. It's now possible to give attributes or items a higher priority
121 by either using dot-notation lookup or the bracket syntax. This also
122 changed the AST slightly. `Subscript` is gone and was replaced with
123 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
125 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
127 - added support for preprocessing and token stream filtering for extensions.
128 This would allow extensions to allow simplified gettext calls in template
129 data and something similar.
131 - added :meth:`jinja2.environment.TemplateStream.dump`.
133 - added missing support for implicit string literal concatenation.
134 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
136 - `else` is optional for conditional expressions. If not given it evaluates
139 - improved error reporting for undefined values by providing a position.
141 - `filesizeformat` filter uses decimal prefixes now per default and can be
142 set to binary mode with the second parameter.
144 - fixed bug in finalizer
148 (no codename, released on June 9th 2008)
150 - first release of Jinja2
