Python 3.7.7rc1

Release Date: March 4, 2020

Note

Python 3.8 is now the latest feature release series of Python 3. Get the latest release of 3.8.x here. We plan to continue to provide bugfix releases for 3.7.x until mid 2020 and security fixes until mid 2023.

Python 3.7.7rc1 is the release candidate preview of the seventh and most recent maintenance release of Python 3.7. The Python 3.7 series contains many new features and optimizations.

Note that 3.7.7rc1 is a release preview and thus its use is not recommended for production environments.

Please see What’s New In Python 3.7 for more information.

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.
