0.4.6

Released: 2018-09-28

Bugfixes

• A fair number of documentation fixes -- better explanations, formatting fixes,
  broken internal links.
• Fix bug in Makefile introduced in 0.4.4 where fields submodule wasn't
  detected as a dependency for testing and documentation building.
• Work around installation crash while testing on Python 3.4, due to a known race
  condition in setuptools.

Other Changes

• Dependencies:
  • Bump Python 3.6 testing version to 3.6.6.
  • Minimum required pytest version is now 3.1.
  • Now compatible with tox 3.x.
• Use 3.7.0 as the default version for running stuff and testing.
• Add deprecation warnings for (almost) all dictionary methods in Struct.
  They've been deprecated since 0.4.1 but I didn't add the warnings.
