macOS 10.15 (Catalina) Gatekeeper Requirements [changed in 3.8.2]\
\f0\b0 \ulnone \
-As of 2020-02-03, Apple has changed how third-party installer packages, like those provided by python.org, are notarized for verification by Gatekeeper and begun enforcing additional requirements such as code signing and use of the hardened runtime. As of 3.8.2, python.org installer packages now meet those additional notarization requirements. The necessary changes in packaging should be transparent to your use of Python but, in the unlikely event that you encounter changes in behavior between 3.8.1 and 3.8.2 in areas like ctypes, importlib, or mmap, please check bugs.python.org for existing reports and, if necessary, open a new issue.\

+\f0\b0 \cf0 \ulnone Python 2.7 has now reached end-of-life. As of Python 3.8.3, the
+\f3 Python Launcher
+\f0 app now has
+\f3 python3
+\f0 factory defaults. Also, the
+\f3 Current
+\f0 link in the
+\f3 /Library/Frameworks/Python.framework/Versions
+\f0 directory is now updated to point to the Python 3 being installed; previously, only Python 2 installs updated
+\f3 Current
+\f0 . This change might affect developers using the framework to embed Python in their applications. If another version is desired for embedding, the
+\f3 Current
+\f0 symlink can be changed manually without affecting 3.8.x behavior.\
