Release Notes

nedbat/coveragepy (coverage)

v7.6.3

Compare Source

• Fix: nested context managers could incorrectly be analyzed to flag a missing
  branch on the last context manager, as described in issue 1876_. This is
  now fixed.

• Fix: the missing branch message about not exiting a module had an extra
  "didn't," as described in issue 1873_. This is now fixed.
