dbus Python Bindings 1.2.16 (2020-01-14)
========================================

The “bag of assorted swords” release.

Enhancements:

• All tests are run even if the tap.py module is not available, although
  diagnostics for failing tests will be better if it is present.
  (Simon McVittie)

Fixes:

• Forbid unexpanded AX-prefixed macros more selectively, similar to
  dbus#249. (Simon McVittie)
