-Subject: [ANN] PyYAML-5.3.1: YAML parser and emitter for Python
+Subject: [ANN] PyYAML-5.4 Released
 
-=======================
-Announcing PyYAML-5.3.1
-=======================
+=====================
+Announcing PyYAML-5.4
+=====================
 
 A new release of PyYAML is now available:
-https://pypi.org/project/PyYAML/
+https://github.com/yaml/pyyaml/releases/tag/5.4
 
-This release contains a security fix for CVE-2020-1747. FullLoader was still
-exploitable for arbitrary command execution.
-https://bugzilla.redhat.com/show_bug.cgi?id=1807367
+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).
 
-Thanks to Riccardo Schirone (https://github.com/ret2libc) for both reporting
-this and providing the fixes to resolve it.
