6 (codename to be selected, release date to be announced)
8 - Choice and prefix loaders now dispatch source and template lookup
9 separately in order to work in combination with module loaders as
11 - Fixed filesizeformat.
12 - Added a non-silent option for babel extraction.
13 - Added `urlencode` filter that automatically quotes values for
14 URL safe usage with utf-8 as only supported encoding. If applications
15 want to change this encoding they can override the filter.
16 - Accessing `last` on the loop context no longer causes the iterator
17 to be consumed into a list.
21 (codename Convolution, released on July 24th 2011)
23 - internal attributes now raise an internal attribute error now instead
24 of returning an undefined. This fixes problems when passing undefined
25 objects to Python semantics expecting APIs.
26 - traceback support now works properly for PyPy. (Tested with 1.4)
27 - implemented operator intercepting for sandboxed environments. This
28 allows application developers to disable builtin operators for better
29 security. (For instance limit the mathematical operators to actual
30 integers instead of longs)
31 - groupby filter now supports dotted notation for grouping by attributes
33 - scoped blocks now properly treat toplevel assignments and imports.
34 Previously an import suddenly "disappeared" in a scoped block.
35 - automatically detect newer Python interpreter versions before loading code
36 from bytecode caches to prevent segfaults on invalid opcodes. The segfault
37 in earlier Jinja2 versions here was not a Jinja2 bug but a limitation in
38 the underlying Python interpreter. If you notice Jinja2 segfaulting in
39 earlier versions after an upgrade of the Python interpreter you don't have
40 to upgrade, it's enough to flush the bytecode cache. This just no longer
41 makes this necessary, Jinja2 will automatically detect these cases now.
42 - the sum filter can now sum up values by attribute. This is a backwards
43 incompatible change. The argument to the filter previously was the
44 optional starting index which defaultes to zero. This now became the
45 second argument to the function because it's rarely used.
46 - like sum, sort now also makes it possible to order items by attribute.
47 - like sum and sort, join now also is able to join attributes of objects
49 - the internal eval context now has a reference to the environment.
50 - added a mapping test to see if an object is a dict or an object with
55 (re-release of 2.5.4 with built documentation removed for filesize.
56 Released on October 18th 2010)
58 - built documentation is no longer part of release.
62 (bugfix release, released on October 17th 2010)
64 - Fixed extensions not loading properly with overlays.
65 - Work around a bug in cpython for the debugger that causes segfaults
66 on 64bit big-endian architectures.
70 (bugfix release, released on October 17th 2010)
72 - fixed an operator precedence error introduced in 2.5.2. Statements
73 like "-foo.bar" had their implicit parentheses applied around the
74 first part of the expression ("(-foo).bar") instead of the more
79 (bugfix release, released on August 18th 2010)
81 - improved setup.py script to better work with assumptions people
82 might still have from it (``--with-speedups``).
83 - fixed a packaging error that excluded the new debug support.
87 (bugfix release, released on August 17th 2010)
89 - StopIteration exceptions raised by functions called from templates
90 are now intercepted and converted to undefineds. This solves a
91 lot of debugging grief. (StopIteration is used internally to
92 abort template execution)
93 - improved performance of macro calls slightly.
94 - babel extraction can now properly extract newstyle gettext calls.
95 - using the variable `num` in newstyle gettext for something else
96 than the pluralize count will no longer raise a :exc:`KeyError`.
97 - removed builtin markup class and switched to markupsafe. For backwards
98 compatibility the pure Python implementation still exists but is
99 pulled from markupsafe by the Jinja2 developers. The debug support
100 went into a separate feature called "debugsupport" and is disabled
101 by default because it is only relevant for Python 2.4
102 - fixed an issue with unary operators having the wrong precendence.
106 (codename Incoherence, relased on May 29th 2010)
108 - improved the sort filter (should have worked like this for a
109 long time) by adding support for case insensitive searches.
110 - fixed a bug for getattribute constant folding.
111 - support for newstyle gettext translations which result in a
112 nicer in-template user interface and more consistent
113 catalogs. (:ref:`newstyle-gettext`)
114 - it's now possible to register extensions after an environment
119 (bugfix release, released on April 20th 2010)
121 - fixed an error reporting bug for undefineds.
125 (codename Correlation, released on April 13th 2010)
127 - the environment template loading functions now transparently
128 pass through a template object if it was passed to it. This
129 makes it possible to import or extend from a template object
130 that was passed to the template.
131 - added a :class:`ModuleLoader` that can load templates from
132 precompiled sources. The environment now features a method
133 to compile the templates from a configured loader into a zip
135 - the _speedups C extension now supports Python 3.
136 - added support for autoescaping toggling sections and support
137 for evaluation contexts (:ref:`eval-context`).
138 - extensions have a priority now.
142 (bugfix release, released on February 19th 2010)
144 - fixed an error reporting bug on all python versions
145 - fixed an error reporting bug on Python 2.4
149 (3000 Pythons, released on February 10th 2010)
151 - fixes issue with code generator that causes unbound variables
152 to be generated if set was used in if-blocks and other small
154 - include tags are now able to select between multiple templates
155 and take the first that exists, if a list of templates is
157 - fixed a problem with having call blocks in outer scopes that
158 have an argument that is also used as local variable in an
160 - greatly improved error message reporting (#339)
161 - implicit tuple expressions can no longer be totally empty.
162 This change makes ``{% if %}...{% endif %}`` a syntax error
164 - added support for translator comments if extracted via babel.
165 - added with-statement extension.
166 - experimental Python 3 support.
170 (bugfix release, released on September 14th 2009)
172 - fixes some smaller problems for Jinja2 on Jython.
176 (codename Kong, released on September 13th 2009)
178 - Include statements can now be marked with ``ignore missing`` to skip
179 non existing templates.
180 - Priority of `not` raised. It's now possible to write `not foo in bar`
181 as an alias to `foo not in bar` like in python. Previously the grammar
182 required parentheses (`not (foo in bar)`) which was odd.
183 - Fixed a bug that caused syntax errors when defining macros or using the
184 `{% call %}` tag inside loops.
185 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
186 - Made it possible to refer to names from outer scopes in included templates
187 that were unused in the callers frame (#327)
188 - Fixed a bug that caused internal errors if names where used as iteration
189 variable and regular variable *after* the loop if that variable was unused
190 *before* the loop. (#331)
191 - Added support for optional `scoped` modifier to blocks.
192 - Added support for line-comments.
193 - Added the `meta` module.
194 - Renamed (undocumented) attribute "overlay" to "overlayed" on the
195 environment because it was clashing with a method of the same name.
196 - speedup extension is now disabled by default.
202 - Fixed a translation error caused by looping over empty recursive loops.
206 (codename Yasuzō, released on November 23rd 2008)
208 - fixed a bug with nested loops and the special loop variable. Before the
209 change an inner loop overwrote the loop variable from the outer one after
212 - fixed a bug with the i18n extension that caused the explicit pluralization
213 block to look up the wrong variable.
215 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
217 - index based subscribing of variables with a constant value returns an
218 undefined object now instead of raising an index error. This was a bug
219 caused by eager optimizing.
221 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
222 if an translations object is installed. This makes dealing with custom
223 translations classes easier.
225 - fixed a confusing behavior with conditional extending. loops were partially
226 executed under some conditions even though they were not part of a visible
229 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
231 - fixed a bug with empty statements in macros.
233 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
235 - the template context is now weakref-able
237 - inclusions and imports "with context" forward all variables now, not only
240 - added a cycle helper called `cycler`.
242 - added a joining helper called `joiner`.
244 - added a `compile_expression` method to the environment that allows compiling
245 of Jinja expressions into callable Python objects.
247 - fixed an escaping bug in urlize
251 (codename jinjavitus, released on July 17th 2008)
253 - the subscribing of objects (looking up attributes and items) changed from
254 slightly. It's now possible to give attributes or items a higher priority
255 by either using dot-notation lookup or the bracket syntax. This also
256 changed the AST slightly. `Subscript` is gone and was replaced with
257 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
259 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
261 - added support for preprocessing and token stream filtering for extensions.
262 This would allow extensions to allow simplified gettext calls in template
263 data and something similar.
265 - added :meth:`jinja2.environment.TemplateStream.dump`.
267 - added missing support for implicit string literal concatenation.
268 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
270 - `else` is optional for conditional expressions. If not given it evaluates
273 - improved error reporting for undefined values by providing a position.
275 - `filesizeformat` filter uses decimal prefixes now per default and can be
276 set to binary mode with the second parameter.
278 - fixed bug in finalizer
282 (no codename, released on June 9th 2008)
284 - first release of Jinja2
