Prefix loader was not forwarding the locals properly to
inner loaders. This is now fixed.
Security issue: Changed the default folder for the filesystem cache to be
user specific and read and write protected on UNIX systems. See Debian bug
734747 for more information.
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.
Added keep-trailing-newline configuration to environments and
templates to optionally preserve the final trailing newline.
Accessing last on the loop context no longer causes the iterator
to be consumed into a list.
Python requirement changed: 2.6, 2.7 or >= 3.3 are required now,
supported by same source code, using the “six” compatibility library.
Allow contextfunction and other decorators to be applied to __call__.
Added support for changing from newline to different signs in the wordwrap
filter.
Added support for ignoring memcache errors silently.
Added support for keeping the trailing newline in templates.
Added finer grained support for stripping whitespace on the left side
of blocks.
Added map, select, reject, selectattr and rejectattr
filters.
Added support for loop.depth to figure out how deep inside a recursive
loop the code is.
(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 “disappeared” in a scoped block.
automatically detect newer Python interpreter versions before loading code
from bytecode caches to prevent segfaults on invalid opcodes. The segfault
in earlier Jinja2 versions here was not a Jinja2 bug but a limitation in
the underlying Python interpreter. If you notice Jinja2 segfaulting in
earlier versions after an upgrade of the Python interpreter you don’t have
to upgrade, it’s enough to flush the bytecode cache. This just no longer
makes this necessary, Jinja2 will automatically detect these cases now.
the sum filter can now sum up values by attribute. This is a backwards
incompatible change. The argument to the filter previously was the
optional starting index which defaultes to zero. This now became the
second argument to the function because it’s rarely used.
like sum, sort now also makes it possible to order items by attribute.
like sum and sort, join now also is able to join attributes of objects
as string.
the internal eval context now has a reference to the environment.
added a mapping test to see if an object is a dict or an object with
a similar interface.
fixed an operator precedence error introduced in 2.5.2. Statements
like “-foo.bar” had their implicit parentheses applied around the
first part of the expression (“(-foo).bar”) instead of the more
correct “-(foo.bar)”.
StopIteration exceptions raised by functions called from templates
are now intercepted and converted to undefineds. This solves a
lot of debugging grief. (StopIteration is used internally to
abort template execution)
improved performance of macro calls slightly.
babel extraction can now properly extract newstyle gettext calls.
using the variable num in newstyle gettext for something else
than the pluralize count will no longer raise a KeyError.
removed builtin markup class and switched to markupsafe. For backwards
compatibility the pure Python implementation still exists but is
pulled from markupsafe by the Jinja2 developers. The debug support
went into a separate feature called “debugsupport” and is disabled
by default because it is only relevant for Python 2.4
fixed an issue with unary operators having the wrong precendence.
(codename Correlation, released on April 13th 2010)
the environment template loading functions now transparently
pass through a template object if it was passed to it. This
makes it possible to import or extend from a template object
that was passed to the template.
added a 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 (Evaluation Context).
Include statements can now be marked with ignoremissing to skip
non existing templates.
Priority of not raised. It’s now possible to write not foo in bar
as an alias to foo not in bar like in python. Previously the grammar
required parentheses (not (foo in bar)) which was odd.
Fixed a bug that caused syntax errors when defining macros or using the
{% call %} tag inside loops.
Fixed a bug in the parser that made {{foo[1,2]}} impossible.
Made it possible to refer to names from outer scopes in included templates
that were unused in the callers frame (#327)
Fixed a bug that caused internal errors if names where used as iteration
variable and regular variable after the loop if that variable was unused
before the loop. (#331)
Added support for optional scoped modifier to blocks.
Added support for line-comments.
Added the meta module.
Renamed (undocumented) attribute “overlay” to “overlayed” on the
environment because it was clashing with a method of the same name.
fixed a bug with nested loops and the special loop variable. Before the
change an inner loop overwrote the loop variable from the outer one after
iteration.
fixed a bug with the i18n extension that caused the explicit pluralization
block to look up the wrong variable.
fixed a limitation in the lexer that made {{foo.0.0}} impossible.
index based subscribing of variables with a constant value returns an
undefined object now instead of raising an index error. This was a bug
caused by eager optimizing.
the i18n extension looks up foo.ugettext now followed by foo.gettext
if an translations object is installed. This makes dealing with custom
translations classes easier.
fixed a confusing behavior with conditional extending. loops were partially
executed under some conditions even though they were not part of a visible
area.
added sort filter that works like dictsort but for arbitrary sequences.
the subscribing of objects (looking up attributes and items) changed from
slightly. It’s now possible to give attributes or items a higher priority
by either using dot-notation lookup or the bracket syntax. This also
changed the AST slightly. Subscript is gone and was replaced with
Getitem and Getattr.
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.
