 Announcing PyYAML-5.1b1 (First beta release)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The first beta release of PyYAML-5.1 has been uploaded to pypi.org. The
final
release is expected to land in the next 2 weeks. Normally we would only
announce the final release, but this one has been a long time coming and ha=
s
major changes, so we want people to know about the release process early on=
.


A new MAJOR RELEASE of PyYAML is now available:
https://pypi.org/project/PyYAML/

This is the first major release of PyYAML under the new maintenance team.

Among the many changes listed below, this release specifically addresses th=
e
arbitrary code execution issue raised by:

    https://nvd.nist.gov/vuln/detail/CVE-2017-18342

(See https://github.com/yaml/pyyaml/wiki/PyYAML-yaml.load(input)-Deprecatio=
n
for complete details).

The PyYAML project is now maintained by the YAML and Python communities.
Planning happens on the #yaml-dev, #pyyaml and #libyaml IRC channels on
irc.freenode.net.

About PyYAML
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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 standar=
d
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.
