The trust certificates in system and user keychains managed by the 17\f2\i Keychain Access 18\f0\i0 application and the 19\f2\i security 20\f0\i0 command line utility are not used as defaults by the Python 21\f3 ssl 22\f0 module. A sample command script is included in 23\f3 /Applications/Python 3.8 24\f0 to install a curated bundle of default root certificates from the third-party 25\f3 certifi 26\f0 package ({\field{\*\fldinst{HYPERLINK "https://pypi.org/project/certifi/"}}{\fldrslt https://pypi.org/project/certifi/}}). Double-click on 27\f3 Install Certificates 28\f0 to run it.\ 29\ 30The bundled 31\f3 pip 32\f0 has its own default certificate store for verifying download connections.\ 33\ 34 35\f1\b \ul Using IDLE or other Tk applications 36\f0\b0 \ulnone \ 37\ 38This package includes its own private version of Tcl/Tk 8.6. It does not use any system-supplied or third-party supplied versions of Tcl/Tk.\ 39\ 40Due to new security checks on macOS 10.15 Catalina, when launching IDLE macOS may open a window with a message 41\f1\b "Python" would like to access files in your Documents folder 42\f0\b0 . This is normal as IDLE uses your 43\f1\b Documents 44\f0\b0 folder as its default when opening and saving files; you can still choose other locations in the 45\f1\b Open 46\f0\b0 and 47\f1\b Save 48\f0\b0 file dialog windows. Click on the 49\f1\b OK 50\f0\b0 button to proceed.\ 51 52\f1\b \ul \ 53macOS 10.15 (Catalina) Gatekeeper Requirements [changed in 3.8.2]\ 54 55\f0\b0 \ulnone \ 56As 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 newer 3.8.x releases in areas like ctypes, importlib, or mmap, please check bugs.python.org for existing reports and, if necessary, open a new issue.\ 57 58\f1\b \ul \ 59Python 2.7 end-of-life [changed in 3.8.4]\ 60\ 61 62\f0\b0 \ulnone Python 2.7 has now reached end-of-life. As of Python 3.8.4, the 63\f3 Python Launcher 64\f0 app now has 65\f3 python3 66\f0 factory defaults. Also, the 67\f3 Current 68\f0 link in the 69\f3 /Library/Frameworks/Python.framework/Versions 70\f0 directory is now updated to point to the Python 3 being installed; previously, only Python 2 installs updated 71\f3 Current 72\f0 . This change might affect developers using the framework to embed Python in their applications. If another version is desired for embedding, the 73\f3 Current 74\f0 symlink can be changed manually without affecting 3.8.x behavior.\ 75 76\f1\b \ul \ 77Other changes\ 78 79\f0\b0 \ulnone \ 80For other changes in this release, see the 81\f2\i What's new 82\f0\i0 section in the {\field{\*\fldinst{HYPERLINK "https://www.python.org/doc/"}}{\fldrslt Documentation Set}} for this release and its 83\f2\i Release Notes 84\f0\i0 link at {\field{\*\fldinst{HYPERLINK "https://www.python.org/downloads/"}}{\fldrslt https://www.python.org/downloads/}}.\ 85}
