===================== Announcing PyYAML-5.4 ===================== A new release of PyYAML is now available: https://github.com/yaml/pyyaml/releases/tag/5.4 This release contains a security fix for CVE-2020-14343. It removes the python/module, python/object, and python/object/new tags from the FullLoader. YAML that uses these tags must be loaded by UnsafeLoader, or a custom loader that has explicitly enabled them. This release also adds Python wheels for manylinux1 (x86_64) and MacOS (x86_64) with the libyaml extension included (built on libyaml 0.2.5). PyYAML 5.4 will be the last release to support Python 2.7 (except for possible critical bug fix releases). Changes ======= * https://github.com/yaml/pyyaml/pull/407 -- build modernization, remove distutils, fix metadata, build wheels, CI to GHA * https://github.com/yaml/pyyaml/pull/472 -- fix for CVE-2020-14343, moves arbitrary python tags to UnsafeLoader * https://github.com/yaml/pyyaml/pull/441 -- fix memory leak in implicit resolver setup * https://github.com/yaml/pyyaml/pull/392 -- fix py2 copy support for timezone objects * https://github.com/yaml/pyyaml/pull/378 -- fix compatibility with Jython Resources ========= PyYAML IRC Channel: #pyyaml on irc.freenode.net PyYAML homepage: https://github.com/yaml/pyyaml PyYAML documentation: http://pyyaml.org/wiki/PyYAMLDocumentation Source and binary installers: https://pypi.org/project/PyYAML/ GitHub repository: https://github.com/yaml/pyyaml/ Bug tracking: https://github.com/yaml/pyyaml/issues YAML homepage: http://yaml.org/ YAML-core mailing list: http://lists.sourceforge.net/lists/listinfo/yaml-core 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'}
