 Announcing PyYAML-4.1

A new MAJOR RELEASE of PyYAML is now available:

This is the first release of PyYAML under a new maintenance team. In August
2016, maintenance of PyYAML and LibYAML was turned over from the original
author, Kirill Simonov, to Ian Cordasco and Ingy döt Net.

The canonical source repo moved:

    from: https://bitbucket.org/xi/pyyaml/
    to:   https://github.com/yaml/pyyaml

The PyYAML project is now maintained by the YAML and Python communities.

About PyYAML

YAML is a data serialization format designed for human readability and
interaction with scripting languages. PyYAML is a YAML parser and emitter

PyYAML features a complete YAML 1.1 parser, Unicode support, pickle support,
capable extension API, and sensible error messages. PyYAML supports standard
YAML tags and provides Python-specific tags that allow to represent an
arbitrary Python object.

PyYAML is applicable for a broad range of tasks from complex configuration
files to object serialization and persistence.
