Announcing PyYAML-6.0
A new release of PyYAML is now available:

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