=====================
Announcing PyYAML-6.0
=====================

A new release of PyYAML is now available:
https://github.com/yaml/pyyaml/releases/tag/6.0

The previously-deprecated default loader selection in `yaml.load()` has
been removed; `Loader` is now a required argument.

Support for Python 2.7 and 3.5 has been dropped, and support for Python 3.10
added. It now includes libyaml 0.2.5 extension wheels for MacOS M1
(Apple Silicon/arm64), Linux s390x and Linux aarch64.

Numerous other bugfixes and code cleanups are included in this release.

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
Python.

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.


Example
=======

```
>>> import yaml

>>> yaml.full_load("""
... name: PyYAML
... description: YAML parser and emitter for Python
... homepage: https://github.com/yaml/pyyaml
... keywords: [YAML, serialization, configuration, persistence, pickle]
... """)
{'keywords': ['YAML', 'serialization', 'configuration', 'persistence',
'pickle'], 'homepage': 'https://github.com/yaml/pyyaml', 'description':
