Differences

0.19.1

Fix build on pypy.

0.19.0

Add error message for missing partial template #extends under test.
Fix warnings in python3+.
Drop support for python 2.
Build abi3 wheels.

0.18.0

Some optimizations of list comprehensions
Lookup speed improvements
Remove enable_auto_self setting (always False)

Add an auto_self kwarg to getVar and varExists defaulting to True (will default to False and be removed in a future version).

0.17.0

enable_auto_self setting now defaults to False
Lookup involving partial templates calling partial templates is now optimized.

0.16.1

Add a parsing hook for cheetah variables

0.16.0

$foo()bar no longer compiles to foo.bar
gettext parsing was removed -- it never worked properly. To get gettext scannable compiled output, create a compiler, augment ._global_vars with the gettext functions.
$() and $[] are now syntax errors -- use ${} instead
${ foo } is now a syntax error -- placeholders cannot start with whitespace
Escaped newlines in expressions are preserved
Bug with comments in a multi-line expression fixed
Fix several parsing issues around expressions
Fix several parsing issues around #def

0.15.2

Add an enable_auto_self setting (defaulted to True) which (when enabled) means $foo can mean either self.foo or NS['foo'] (the behaviour prior to this version). In future versions, this will default to False and will eventually be eliminated.

0.15.1

Introduce unused functions for lookup. These will be used for backwards / forwards compatibility in the next release.

0.9.0
