[dependabot]

Bumps restrictedpython from 8.1 to 8.4.

Changelog

Sourced from restrictedpython's changelog.

8.4 (2026-07-10)

• Add type annotations to the package code. For clarification, restricted Python code does not support type annotations.

• Allow ast.Module, ast.Expression and ast.Interactive as body in compile_restricted_function

• Disallow mode="function" in compile_restricted (it never worked).

• Prevent access to string.Formatter and its unsafe traversal methods via safer_getattr. (CVE-2026-76825)

8.3 (2026-06-16)

• Switch to PyPI Trusted Publishing for the package release process

• Also validate positional-only argument names (parameters before /) so they cannot start with an underscore, closing a sandbox escape where a positional-only parameter could shadow an injected protected name such as _getattr_, _getitem_, _write_ or _print_.

8.3a1.dev0 (2026-05-29)

• Allow to use the package with Python 3.15 -- Caution: No security audit has been done so far.

8.2 (2026-05-29)

• Remove documentation that appears to promote unsupported direct guards usage.

• Move package metadata from setup.py to pyproject.toml.

• Drop support for Python 3.9.

• Allow the ... (Ellipsis) statement.
