Changelog

32.1.2

---

• 893: Only release sdist in zip format as warehouse now
  disallows releasing two different formats.

32.1.1

---

• 704: More selectively ensure that 'rmtree' is not invoked with
  a byte string, enabling it to remove files that are non-ascii,
  even on Python 2.

• 712: In 'sandbox.run_setup', ensure that __file__ is
  always a str, modeling the behavior observed by the
  interpreter when invoking scripts and modules.

32.1.0

---

• 891: In 'test' command on test failure, raise DistutilsError,
  suppression invocation of subsequent commands.

32.0.0

---

• 890: Revert 849. global-exclude .foo will not match all
  *.foo files any more. Package authors must add an explicit
  wildcard, such as global-exclude *.foo, to match all
  .foo files. See 886, 849.

31.0.1

---

• 885: Fix regression where 'pkg_resources._rebuild_mod_path'
  would fail when a namespace package's 'path' was not
  a list with a sort attribute.
