+Subject: [ANN] PyYAML-5.3: YAML parser and emitter for Python
 
 =======================
-Announcing PyYAML-5.2
+Announcing PyYAML-5.3
 =======================
 
 A new release of PyYAML is now available:
 https://pypi.org/project/PyYAML/
 
-This fixes some incompatibilities introduced in version 5.1 and also removes
-another possibility of loading arbitrary code.
+This release contains some bugfixes (handling of slots, enable unicode for
+maxunicode < 0xffff, enable large files), enhancements (create timezone
+aware datetimes) and some other small enhancements.
