Python 3.7.9

Release Date: Aug. 17, 2020

Note: The release you are looking at is Python 3.7.9, the final bugfix/security release with binary installers for the legacy 3.7 series which has now reached end-of-life and is no longer supported. See the downloads page for currently supported versions of Python. The final source-only security fix release for 3.7 was 3.7.17.

Binary installers are normally not provided for security fix releases. However, since 3.7.8 was the last 3.7.x bugfix release and there are security fixes published in 3.7.9 that apply to users of some of the binary installers provided with 3.7.8, we have made an exception for 3.7.9 and are also updating the Windows and macOS binary installers. We do not plan to provide further binary updates for future 3.7.x security releases.

Please see the Full Changelog link for more information about the contents of this release and see What’s New In Python 3.7 for more information about 3.7 features.

Windows users

  • The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".)
  • There are now "web-based" installers for Windows platforms; the installer will download the needed software components at installation time.
  • There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.

macOS users

  • Please read the "Important Information" displayed during installation for information about SSL/TLS certificate validation and the running the "Install Certificates.command".
  • As of 3.7.7, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems. The deprecated 64-bit/32-bit installer variant for macOS 10.6 (Snow Leopard) is no longer provided.
  • As of 3.7.7, macOS installer packages are now compatible with the full Gatekeeper notarization requirements of macOS 10.15 Catalina including code signing.
