Sourced from setuptools's changelog.

v82.0.1

Bugfixes

• Fix the loading of launcher manifest.xml file. (#5047)
• Replaced deprecated json.__version__ with fixture in tests. (#5186)

Improved Documentation

• Add advice about how to improve predictability when installing sdists. (#5168)

Misc

• #4941, #5157, #5169, #5175

v82.0.0

Deprecations and Removals

• pkg_resources has been removed from Setuptools. Most common uses of pkg_resources have been superseded by the importlib.resources <https://docs.python.org/3/library/importlib.resources.html>_ and importlib.metadata <https://docs.python.org/3/library/importlib.metadata.html>_ projects. Projects and environments relying on pkg_resources for namespace packages or other behavior should depend on older versions of setuptools. (#3085)

v81.0.0

Deprecations and Removals

• Removed support for the --dry-run parameter to setup.py. This one feature by its nature threads through lots of core and ancillary functionality, adding complexity and friction. Removal of this parameter will help decouple the compiler functionality from distutils and thus the eventual full integration of distutils. These changes do affect some class and function signatures, so any derivative functionality may require some compatibility shims to support their expected interface. Please report any issues to the Setuptools project for investigation. (#4872)

v80.10.2

Bugfixes

• Update vendored dependencies. (#5159)

Features - 21.2.0

• Update embed wheel generator (tasks/upgrade_wheels.py) to include type annotations in generated output - by :user:rahuldevikar. (:issue:3075)

Bugfixes - 21.2.0

• Pass --without-scm-ignore-files to subprocess venv on Python 3.13+ so virtualenv controls .gitignore creation, fixing flaky test_create_no_seed and --no-vcs-ignore being ignored in subprocess path - by :user:gaborbernat. (:issue:3089)
• Use BASH_SOURCE[0] instead of $0 in the bash activate script relocation fallback, fixing incorrect PATH when sourcing the activate script from a different directory - by :user:gaborbernat. (:issue:3090)

v21.1.0 (2026-02-27)

---

Features - 21.1.0

• Add comprehensive type annotations across the entire codebase and ship a PEP 561 py.typed marker so downstream consumers and type checkers recognize virtualenv as an inline-typed package - by :user:rahuldevikar. (:issue:3075)

v21.0.0 (2026-02-25)

---

Deprecations and Removals - 21.0.0

• The Python discovery logic has been extracted into a standalone python-discovery package on PyPI (documentation <https://python-discovery.readthedocs.io/>_) and is now consumed as a dependency. If you previously imported discovery internals directly (e.g. from virtualenv.discovery.py_info import PythonInfo), switch to from python_discovery import PythonInfo. Backward-compatibility re-export shims are provided at virtualenv.discovery.py_info, virtualenv.discovery.py_spec, and virtualenv.discovery.cached_py_info, however these are considered unsupported and may be removed in a future release - by :user:gaborbernat. (:issue:3070)

Features - 20.39.1
