| \b \cf0 **NEW** |
| \b0 For Python 3.6, the python.org website now provides only one installer variant for download: one that installs a |
| \i 64-bit/32-bit Intel |
| \i0 Python capable of running on |
| \i Mac OS X 10.6 (Snow Leopard) |
| \i0 or later. This ReadMe was installed with the |
| \i $MACOSX_DEPLOYMENT_TARGET |
| \i0 variant. By default, Python will automatically run in 64-bit mode if your system supports it. The Python installed by this installer is built with private copies of some third-party libraries not included with or newer than those in OS X itself. The list of these libraries is included at the end of the License.rtf file. |

| |
| \b \cf0 **NEW** |
| \b0 This variant of Python 3.6 now includes its own private copy of OpenSSL 1.0.2. Unlike previous releases, the deprecated Apple-supplied OpenSSL libraries are no longer used. This also means that the trust certificates in system and user keychains managed by the |
| \i Keychain Access |
| \i0 application and the |
| \i security |
| \i0 command line utility are no longer used as defaults by the Python |
| \f1 ssl |
| \f0 module. For 3.6.0b1, a sample command script is included in |
| \f1 /Applications/Python 3.6 |
| \f0 to install a curated bundle of default root certificates from the third-party |
| \f1 certifi |
| \f0 package ({\field{\*\fldinst{HYPERLINK "https://pypi.python.org/pypi/certifi"}}{\fldrslt https://pypi.python.org/pypi/certifi}}). If you choose to use |
| \f1 certifi |
| \f0 , you should consider subscribing to the{\field{\*\fldinst{HYPERLINK "https://certifi.io/en/latest/"}}{\fldrslt project's email update service}} to be notified when the certificate bundle is updated. More options will be provided prior to the final release of 3.6.0.\ |
| \ |
| The bundled |
| \f1 pip |
| \f0 included with the Python 3.6 installer has its own default certificate store for verifying download connections.\ |

| \b \cf0 \ul Update your version of Tcl/Tk to use IDLE or other Tk applications |
| \b0 \ulnone \ |
| \ |
| To use IDLE or other programs that use the Tkinter graphical user interface toolkit, you need to install a newer third-party version of the |
| \i Tcl/Tk |
| \i0 frameworks. Visit {\field{\*\fldinst{HYPERLINK "https://www.python.org/download/mac/tcltk/"}}{\fldrslt https://www.python.org/download/mac/tcltk/}} for current information about supported and recommended versions of |
| \i Tcl/Tk |
| \i0 for this version of Python and of Mac OS X. For the initial preview releases of Python 3.6, the installer is still linked with Tcl/Tk 8.5; this will likely change prior to the final release of 3.6.0.\ |

| Python 3 and Python 2 Co-existence\ |
| |
| \b0 \ulnone \ |
| Python.org Python $VERSION and 2.7.x versions can both be installed on your system and will not conflict. Command names for Python 3 contain a 3 in them, |
| \f1 python3 |
| \f0 (or |
| \f1 python$VERSION |
| \f0 ), |
| \f1 idle3 |
| \f0 (or i |
| \f1 dle$VERSION |
| \f0 ), |
| \f1 pip3 |
| \f0 (or |
| \f1 pip$VERSION |
| \f0 ), etc. Python 2.7 command names contain a 2 or no digit: |
| \f1 python2 |
| \f0 (or |
| \f1 python2.7 |
| \f0 or |
| \f1 python |
| \f0 ), |
| \f1 idle2 |
