CHANGES

6.2 (2025-08-08)

Update safe builtins for Python 3, adding bytes, and removing cmp,
coerce, long, reduce, unichr, and unicode.

Drop support for Python 2.7, 3.5, 3.6.
Make sure the tests do not fail even on unsupported PyPy3 because ZTK might
run them.

Backwards incompatible changes
++++++++++++++++++++++++++++++

Require RestrictedPython >= 4.
Drop support for writing output of print calls to a variable named
untrusted_output. It is now done the same way RestrictedPython
handles printing, i. e. access it trough the variable printed.
.interpreter.CompiledProgram still supports output to a file like object
by implementing accessing the printed data.
The following names are no longer available via __builtins__ as they are
either potentially harmful, not accessible at all or meaningless:
- __debug__
- __name__
- __doc__
- copyright
- credits
- license
- quit
Drop support to run the tests using python setup.py test.
Drop support for Python 2.6.
