6 (codename to be selected, release date to be announced)
8 - internal attributes now raise an internal attribute error now instead
9 of returning an undefined. This fixes problems when passing undefined
10 objects to Python semantics expecting APIs.
11 - traceback support now works properly for PyPy. (Tested with 1.4)
12 - implemented operator intercepting for sandboxed environments. This
13 allows application developers to disable builtin operators for better
14 security. (For instance limit the mathematical operators to actual
15 integers instead of longs)
16 - groupby filter now supports dotted notation for grouping by attributes
18 - scoped blocks not properly treat toplevel assignments and imports.
19 Previously an import suddenly "disappeared" in a scoped block.
20 - automatically detect newer Python interpreter versions before loading code
21 from bytecode caches to prevent segfaults on invalid opcodes. The segfault
22 in earlier Jinja2 versions here was not a Jinja2 bug but a limitation in
23 the underlying Python interpreter. If you notice Jinja2 segfaulting in
24 earlier versions after an upgrade of the Python interpreter you don't have
25 to upgrade, it's enough to flush the bytecode cache. This just no longer
26 makes this necessary, Jinja2 will automatically detect these cases now.
30 (re-release of 2.5.4 with built documentation removed for filesize.
31 Released on October 18th 2010)
33 - built documentation is no longer part of release.
37 (bugfix release, released on October 17th 2010)
39 - Fixed extensions not loading properly with overlays.
40 - Work around a bug in cpython for the debugger that causes segfaults
41 on 64bit big-endian architectures.
45 (bugfix release, released on October 17th 2010)
47 - fixed an operator precedence error introduced in 2.5.2. Statements
48 like "-foo.bar" had their implicit parentheses applied around the
49 first part of the expression ("(-foo).bar") instead of the more
54 (bugfix release, released on August 18th 2010)
56 - improved setup.py script to better work with assumptions people
57 might still have from it (``--with-speedups``).
58 - fixed a packaging error that excluded the new debug support.
62 (bugfix release, released on August 17th 2010)
64 - StopIteration exceptions raised by functions called from templates
65 are now intercepted and converted to undefineds. This solves a
66 lot of debugging grief. (StopIteration is used internally to
67 abort template execution)
68 - improved performance of macro calls slightly.
69 - babel extraction can now properly extract newstyle gettext calls.
70 - using the variable `num` in newstyle gettext for something else
71 than the pluralize count will no longer raise a :exc:`KeyError`.
72 - removed builtin markup class and switched to markupsafe. For backwards
73 compatibility the pure Python implementation still exists but is
74 pulled from markupsafe by the Jinja2 developers. The debug support
75 went into a separate feature called "debugsupport" and is disabled
76 by default because it is only relevant for Python 2.4
77 - fixed an issue with unary operators having the wrong precendence.
81 (codename Incoherence, relased on May 29th 2010)
83 - improved the sort filter (should have worked like this for a
84 long time) by adding support for case insensitive searches.
85 - fixed a bug for getattribute constant folding.
86 - support for newstyle gettext translations which result in a
87 nicer in-template user interface and more consistent
88 catalogs. (:ref:`newstyle-gettext`)
89 - it's now possible to register extensions after an environment
94 (bugfix release, released on April 20th 2010)
96 - fixed an error reporting bug for undefineds.
100 (codename Correlation, released on April 13th 2010)
102 - the environment template loading functions now transparently
103 pass through a template object if it was passed to it. This
104 makes it possible to import or extend from a template object
105 that was passed to the template.
106 - added a :class:`ModuleLoader` that can load templates from
107 precompiled sources. The environment now features a method
108 to compile the templates from a configured loader into a zip
110 - the _speedups C extension now supports Python 3.
111 - added support for autoescaping toggling sections and support
112 for evaluation contexts (:ref:`eval-context`).
113 - extensions have a priority now.
117 (bugfix release, released on February 19th 2010)
119 - fixed an error reporting bug on all python versions
120 - fixed an error reporting bug on Python 2.4
124 (3000 Pythons, released on February 10th 2010)
126 - fixes issue with code generator that causes unbound variables
127 to be generated if set was used in if-blocks and other small
129 - include tags are now able to select between multiple templates
130 and take the first that exists, if a list of templates is
132 - fixed a problem with having call blocks in outer scopes that
133 have an argument that is also used as local variable in an
135 - greatly improved error message reporting (#339)
136 - implicit tuple expressions can no longer be totally empty.
137 This change makes ``{% if %}...{% endif %}`` a syntax error
139 - added support for translator comments if extracted via babel.
140 - added with-statement extension.
141 - experimental Python 3 support.
145 (bugfix release, released on September 14th 2009)
147 - fixes some smaller problems for Jinja2 on Jython.
151 (codename Kong, released on September 13th 2009)
153 - Include statements can now be marked with ``ignore missing`` to skip
154 non existing templates.
155 - Priority of `not` raised. It's now possible to write `not foo in bar`
156 as an alias to `foo not in bar` like in python. Previously the grammar
157 required parentheses (`not (foo in bar)`) which was odd.
158 - Fixed a bug that caused syntax errors when defining macros or using the
159 `{% call %}` tag inside loops.
160 - Fixed a bug in the parser that made ``{{ foo[1, 2] }}`` impossible.
161 - Made it possible to refer to names from outer scopes in included templates
162 that were unused in the callers frame (#327)
163 - Fixed a bug that caused internal errors if names where used as iteration
164 variable and regular variable *after* the loop if that variable was unused
165 *before* the loop. (#331)
166 - Added support for optional `scoped` modifier to blocks.
167 - Added support for line-comments.
168 - Added the `meta` module.
169 - Renamed (undocumented) attribute "overlay" to "overlayed" on the
170 environment because it was clashing with a method of the same name.
171 - speedup extension is now disabled by default.
177 - Fixed a translation error caused by looping over empty recursive loops.
181 (codename Yasuzō, released on November 23rd 2008)
183 - fixed a bug with nested loops and the special loop variable. Before the
184 change an inner loop overwrote the loop variable from the outer one after
187 - fixed a bug with the i18n extension that caused the explicit pluralization
188 block to look up the wrong variable.
190 - fixed a limitation in the lexer that made ``{{ foo.0.0 }}`` impossible.
192 - index based subscribing of variables with a constant value returns an
193 undefined object now instead of raising an index error. This was a bug
194 caused by eager optimizing.
196 - the i18n extension looks up `foo.ugettext` now followed by `foo.gettext`
197 if an translations object is installed. This makes dealing with custom
198 translations classes easier.
200 - fixed a confusing behavior with conditional extending. loops were partially
201 executed under some conditions even though they were not part of a visible
204 - added `sort` filter that works like `dictsort` but for arbitrary sequences.
206 - fixed a bug with empty statements in macros.
208 - implemented a bytecode cache system. (:ref:`bytecode-cache`)
210 - the template context is now weakref-able
212 - inclusions and imports "with context" forward all variables now, not only
215 - added a cycle helper called `cycler`.
217 - added a joining helper called `joiner`.
219 - added a `compile_expression` method to the environment that allows compiling
220 of Jinja expressions into callable Python objects.
222 - fixed an escaping bug in urlize
226 (codename jinjavitus, released on July 17th 2008)
228 - the subscribing of objects (looking up attributes and items) changed from
229 slightly. It's now possible to give attributes or items a higher priority
230 by either using dot-notation lookup or the bracket syntax. This also
231 changed the AST slightly. `Subscript` is gone and was replaced with
232 :class:`~jinja2.nodes.Getitem` and :class:`~jinja2.nodes.Getattr`.
234 For more information see :ref:`the implementation details <notes-on-subscriptions>`.
236 - added support for preprocessing and token stream filtering for extensions.
237 This would allow extensions to allow simplified gettext calls in template
238 data and something similar.
240 - added :meth:`jinja2.environment.TemplateStream.dump`.
242 - added missing support for implicit string literal concatenation.
243 ``{{ "foo" "bar" }}`` is equivalent to ``{{ "foobar" }}``
245 - `else` is optional for conditional expressions. If not given it evaluates
248 - improved error reporting for undefined values by providing a position.
250 - `filesizeformat` filter uses decimal prefixes now per default and can be
251 set to binary mode with the second parameter.
253 - fixed bug in finalizer
257 (no codename, released on June 9th 2008)
259 - first release of Jinja2
