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.
12 - added a :class:`ModuleLoader` that can load templates from
13 precompiled sources. The environment now features a method
14 to compile the templates from a configured loader into a zip
16 - the _speedups C extension now supports Python 3.
17 - added support for autoescaping toggling sections and support
18 for evaluation contexts (:ref:`eval-context`).
22 (bugfix release, released on February 19th 2010)
24 - fixed an error reporting bug on all python versions
25 - fixed an error reporting bug on Python 2.4
29 (3000 Pythons, released on February 10th 2010)
31 - fixes issue with code generator that causes unbound variables
32 to be generated if set was used in if-blocks and other small
34 - include tags are now able to select between multiple templates
35 and take the first that exists, if a list of templates is
37 - fixed a problem with having call blocks in outer scopes that
38 have an argument that is also used as local variable in an
40 - greatly improved error message reporting (#339)
41 - implicit tuple expressions can no longer be totally empty.
42 This change makes ``{% if %}...{% endif %}`` a syntax error
44 - added support for translator comments if extracted via babel.
45 - added with-statement extension.
46 - experimental Python 3 support.
50 (bugfix release, released on September 14th 2009)
52 - fixes some smaller problems for Jinja2 on Jython.
56 (codename Kong, released on September 13th 2009)
58 - Include statements can now be marked with ``ignore missing`` to skip
59 non existing templates.
60 - Priority of `not` raised. It's now possible to write `not foo in bar`
61 as an alias to `foo not in bar` like in python. Previously the grammar
62 required parentheses (`not (foo in bar)`) which was odd.
63 - Fixed a bug that caused syntax errors when defining macros or using the
64 `{% call %}` tag inside loops.
65 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
66 - Made it possible to refer to names from outer scopes in included templates
67 that were unused in the callers frame (#327)
68 - Fixed a bug that caused internal errors if names where used as iteration
69 variable and regular variable *after* the loop if that variable was unused
70 *before* the loop. (#331)
71 - Added support for optional `scoped` modifier to blocks.
72 - Added support for line-comments.
73 - Added the `meta` module.
74 - Renamed (undocumented) attribute "overlay" to "overlayed" on the
75 environment because it was clashing with a method of the same name.
76 - speedup extension is now disabled by default.
82 - Fixed a translation error caused by looping over empty recursive loops.
86 (codename Yasuzō, released on November 23rd 2008)
88 - fixed a bug with nested loops and the special loop variable. Before the
89 change an inner loop overwrote the loop variable from the outer one after
92 - fixed a bug with the i18n extension that caused the explicit pluralization
93 block to look up the wrong variable.
95 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
97 - index based subscribing of variables with a constant value returns an
98 undefined object now instead of raising an index error. This was a bug
99 caused by eager optimizing.
101 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
102 if an translations object is installed. This makes dealing with custom
103 translations classes easier.
105 - fixed a confusing behavior with conditional extending. loops were partially
106 executed under some conditions even though they were not part of a visible
109 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
111 - fixed a bug with empty statements in macros.
113 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
115 - the template context is now weakref-able
117 - inclusions and imports "with context" forward all variables now, not only
120 - added a cycle helper called `cycler`.
122 - added a joining helper called `joiner`.
124 - added a `compile_expression` method to the environment that allows compiling
125 of Jinja expressions into callable Python objects.
127 - fixed an escaping bug in urlize
131 (codename jinjavitus, released on July 17th 2008)
133 - the subscribing of objects (looking up attributes and items) changed from
134 slightly. It's now possible to give attributes or items a higher priority
135 by either using dot-notation lookup or the bracket syntax. This also
136 changed the AST slightly. `Subscript` is gone and was replaced with
137 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
139 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
141 - added support for preprocessing and token stream filtering for extensions.
142 This would allow extensions to allow simplified gettext calls in template
143 data and something similar.
145 - added :meth:`jinja2.environment.TemplateStream.dump`.
147 - added missing support for implicit string literal concatenation.
148 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
150 - `else` is optional for conditional expressions. If not given it evaluates
153 - improved error reporting for undefined values by providing a position.
155 - `filesizeformat` filter uses decimal prefixes now per default and can be
156 set to binary mode with the second parameter.
158 - fixed bug in finalizer
162 (no codename, released on June 9th 2008)
164 - first release of Jinja2
