Sourced from jinja2's changelog.

Version 2.11.1

Unreleased

• Fix a bug that prevented looking up a key after an attribute ({{ data.items[1:] }}) in an async template. 1141

Version 2.11.0

Released 2020-01-27

• Drop support for Python 2.6, 3.3, and 3.4. This will be the last version to support Python 2.7 and 3.5.
• Added a new ChainableUndefined class to support getitem and getattr on an undefined object. 977
• Allow {%+ syntax (with NOP behavior) when lstrip_blocks is disabled. 748
• Added a default parameter for the map filter. 557
• Exclude environment globals from meta.find_undeclared_variables. 931
• Float literals can be written with scientific notation, like 2.56e-3. 912, 922
• Int and float literals can be written with the '_' separator for legibility, like 12_345. 923
• Fix a bug causing deadlocks in LRUCache.setdefault. 1000
• The trim filter takes an optional string of characters to trim. 828
• A new jinja2.ext.debug extension adds a {% debug %} tag to quickly dump the current context and available filters and tests. 174, 798, 983
• Lexing templates with large amounts of whitespace is much faster. 857, 858
• Parentheses around comparisons are preserved, so {{ 2 * (3 < 5) }} outputs "2" instead of "False". 755, 938
• Add new boolean, false, true, integer and float tests. 824
• The environment's finalize function is only applied to the output of expressions (constant or not), not static template data. 63
• When providing multiple paths to FileSystemLoader, a template can have the same name as a directory. 821
• Always return Undefined when omitting the else clause in a {{ 'foo' if bar }} expression, regardless of the environment's undefined class. Omitting the else clause is a valid shortcut and should not raise an error when using StrictUndefined. 710, 1079
• Fix behavior of loop control variables such as length and revindex0 when looping over a generator. 459, 751, 794, 993
• Async support is only loaded the first time an environment enables it, in order to avoid a slow initial import. 765
• In async environments, the |map filter will await the filter call if needed. 913
• In for loops that access loop attributes, the iterator is not advanced ahead of the current iteration unless length, revindex, nextitem, or last are accessed. This makes it less likely to break groupby results. 555, 1101
• In async environments, the loop attributes length and revindex work for async iterators. 1101
• In async environments, values from attribute/property access will be awaited if needed. 1101
• ~loader.PackageLoader doesn't depend on setuptools or pkg_resources. 970
• PackageLoader has limited support for 420 namespace packages. 1097
• Support os.PathLike objects in ~loader.FileSystemLoader and ~loader.ModuleLoader. 870
• ~nativetypes.NativeTemplate correctly handles quotes between expressions. "'{{ a }}', '{{ b }}'" renders as the tuple ('1', '2') rather than the string '1, 2'. 1020
• Creating a ~nativetypes.NativeTemplate directly creates a ~nativetypes.NativeEnvironment instead of a default Environment. 1091
• After calling LRUCache.copy(), the copy's queue methods point to the correct queue. 843
• Compiling templates always writes UTF-8 instead of defaulting to the system encoding. 889
• |wordwrap filter treats existing newlines as separate paragraphs to be wrapped individually, rather than creating short intermediate lines. 175
• Add break_on_hyphens parameter to |wordwrap filter. 550
• Cython compiled functions decorated as context functions will be passed the context. 1108
• When chained comparisons of constants are evaluated at compile time, the result follows Python's behavior of returning False if any comparison returns False, rather than only the last one. 1102
• Tracebacks for exceptions in templates show the correct line numbers and source for Python >= 3.7. 1104
• Tracebacks for template syntax errors in Python 3 no longer show internal compiler frames. 763
• Add a DerivedContextReference node that can be used by extensions to get the current context and local variables such as loop. 860
• Constant folding during compilation is applied to some node types that were previously overlooked. 733
• TemplateSyntaxError.source is not empty when raised from an included template. 457
