The variant is built with the same compiler as before. The 10.6 variant now sets CC=gcc instead of CC=gcc-4.2 and does not search for the outdated 10.6 SDK. In addition, both installer variants have updated 3rd-party libraries: This perhaps will also make it easier to transition to the 10.9+ variant as the default for 3.7.0. I expect that most Binary extension modules (including wheels) built for earlier versions of 3.6.x with the 10.6 variant should continue to work with either 3.6.5 variant without recompilation. For 3.6.5, the 10.9+ variant will be offered as an additional alternative to the traditional 10.6+ variant in earlier 3.6.x releases. Also this gives a way to finally provide batteries-included Tcl/Tk support (the single most-requested feature for the macOS installers) and move to Tcl/Tk 8.6.x which is not well supported on older macOS releases (ActiveState currently only supplies 8.6.x binaries for macOS 10.9+, for example). Apple has started deprecating 32-bit support on macOS and apparently plans to drop it entirely in an upcoming release. The rationale is that, while the 10.6 variant is still upwards compatible on current systems, it is showing its age.

Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install installer and framework enhancements and changes for 3.7.0, 3.6.5, and 2.7.15Ĭreated on 11:58 by ned.deily, last changed 14:58 by admin. Both installer variants include private copies of OpenSSL 1.1.0.
Consider using the new 10.9 64-bit-only installer variant, unless you are building Python applications that also need to work on older macOS systems.
Both variants now come with batteries-included versions oF Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications third-party and system versions of Tcl/Tk are no longer used. We also continue to provide a 64-bit/32-bit variant that works on all versions of macOS from 10.6 (Snow Leopard) on. The default variant is 64-bit-only and works on macOS 10.9 (Mavericks) and later systems. For 3.7.0, we provide two binary installer options for download.Please see What’s New In Python 3.7 for more information.
