v3.6.6

[wwkimball]

Enhancements:

• Support ruamel.yaml up to version 0.17.21.

Bug Fixes:

• YAML timestamp values could not be created via yamlpath tools or its library,
  per http://yaml.org/type/timestamp.html.
  Thanks again go to https://github.com/AndydeCleyre!
  • CAUTION 1: ruamel.yaml seems to force all timestamps to UTC while it loads
    YAML/JSON/Compatible data. So, when the timestamp value contains time-zone
    data, it will be stripped off after it is applied to the timestamp value.
    The yamlpath library reverses this when emitting the affected values but if
    you attempt to load the timestamp values directly in the DOM, you'll end up
    with the UTC-converted value, stripped of any time-zone specification. If
    you need the original, unmodified data as a time-zone aware
    datetime.datetime value, pass it through the helper method,
    Nodes.get_timestamp_with_tzinfo(data: AnchoredTimeStamp).
  • CAUTION 2: In order to support timestamp parsing, this project now depends
    on the python-dateutil library. Be sure to install it!

WARNING: DO NOT INSTALL VERSION 3.6.6!

Nothing in my automated testing showed any problems with the release, yet a critical ruamel.yaml patch file failed to be included in the package. This has caused version 3.6.6 to be entirely unusable. Please skip to version 3.6.7, which appears to include the missing file.
