Announcing PyYAML-6.0b1
===

A new beta release of PyYAML is now available:
https://github.com/yaml/pyyaml/releases/tag/6.0b1

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.


Changes
===

Markdown

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':
'YAML parser and emitter for Python', 'name': 'PyYAML'}

>>> print(yaml.dump(_))
name: PyYAML

[ANN] PyYAML-4.1: ***RETRACTED***

2018-06-28 Thread Ingy dot Net 
I am sorry to report that the PyYAML-4.1 release from 48 hours ago has been
removed from PyPI

There were too many problems to make this a viable release.

The biggest known issue with this retraction is that PyYAML will not work
with the new Python 3.7  until PyYAML-4.2 is released.
https://github.com/yaml/pyyaml/issues/126#issuecomment-401175258

We are starting work immediately on 4.2b1 prerelease series. I hope to see
4.2 released in the next few days.

Work is being coordinated on #pyyaml on irc.freenode.net and issues can be
reported and followed at https://github.com/yaml/pyyaml

Thank you for your patience.

[ANN] PyYAML-3.13: YAML parser and emitter for Python

2018-07-05 Thread Ingy dot Net 

 Announcing PyYAML-3.13


A new bug fix release of PyYAML is now available:

http://pyyaml.org/wiki/PyYAML

*** Important Note From Maintainers ***

This is the first PyYAML release by the new maintainers. It was made
critical
because PyYAML-3.12 did not work with the recent Python 3.7 release.

A more ambitious 4.1 release was attempted last week and needed to be
retracted
for many reasons. We apologize any pain caused by the 4.1 removal, but we
remain confident that it was the best decision.

There are over 60 pull requests in PyYAML and LibYAML that will be
represented
in the upcoming 4.2 release and we are working hard to get those to you as
soon
as the release is ready (but no sooner :).

We are are excited that the PyYAML project is moving forward again.

-- The PyYAML Maintenance Team



Changes
===

* Rebuilt with the latest Cython to support the new Python 3.7 release.
* No functionality is different from PyYAML 3.12 in this release.
