Version 2.7

(codename to be selected, release date to be announced)

Choice and prefix loaders now dispatch source and template lookup separately in order to work in combination with module loaders as advertised.
Fixed filesizeformat.
Added a non-silent option for babel extraction.
Added urlencode filter that automatically quotes values for URL safe usage with utf-8 as only supported encoding. If applications want to change this encoding they can override the filter.
Accessing last on the loop context no longer causes the iterator to be consumed into a list.

(codename Convolution, released on July 24th 2011)

internal attributes now raise an internal attribute error now instead of returning an undefined. This fixes problems when passing undefined objects to Python semantics expecting APIs.
traceback support now works properly for PyPy. (Tested with 1.4)
implemented operator intercepting for sandboxed environments. This allows application developers to disable builtin operators for better security. (For instance limit the mathematical operators to actual integers instead of longs)
groupby filter now supports dotted notation for grouping by attributes of attributes.
scoped blocks now properly treat toplevel assignments and imports. Previously an import suddenly &"https://www.xnip.cn/doc/jinja-extensions" >新样式 Gettext)
it&"https://www.xnip.cn/doc/jinja-api" title="jinja2.ModuleLoader">ModuleLoader that can load templates from precompiled sources. The environment now features a method to compile the templates from a configured loader into a zip file or folder.
the _speedups C extension now supports Python 3.
added support for autoescaping toggling sections and support for evaluation contexts (求值上下文).
extensions have a priority now.

(bugfix release, released on February 19th 2010)

(3000 Pythons, released on February 10th 2010)

fixes issue with code generator that causes unbound variables to be generated if set was used in if-blocks and other small identifier problems.
include tags are now able to select between multiple templates and take the first that exists, if a list of templates is given.
fixed a problem with having call blocks in outer scopes that have an argument that is also used as local variable in an inner frame ("https://www.xnip.cn/doc/jinja-api" >字节码缓存)
the template context is now weakref-able
inclusions and imports &"https://www.xnip.cn/doc/jinja-extensions" title="jinja2.nodes.Getitem">Getitem and Getattr.
For more information see the implementation details.
added support for preprocessing and token stream filtering for extensions. This would allow extensions to allow simplified gettext calls in template data and something similar.
added jinja2.environment.TemplateStream.dump().
added missing support for implicit string literal concatenation. {{ "foo" "bar" }} is equivalent to {{ "foobar" }}
else is optional for conditional expressions. If not given it evaluates to false.
improved error reporting for undefined values by providing a position.
filesizeformat filter uses decimal prefixes now per default and can be set to binary mode with the second parameter.
fixed bug in finalizer

(no codename, released on June 9th 2008)
