Also, the 77\f3 Current 78\f0 link in the 79\f3 /Library/Frameworks/Python.framework/Versions 80\f0 directory is now updated to point to the Python 3 being installed; previously, only Python 2 installs updated 81\f3 Current 82\f0 . This change might affect developers using the framework to embed Python in their applications. If another version is desired for embedding, the 83\f3 Current 84\f0 symlink can be changed manually without affecting 3.7.x behavior.\ 85\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardirnatural\partightenfactor0 86 87\f1\b \cf0 \ul \ 88Other changes\ 89\ 90\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardirnatural\partightenfactor0 91 92\f0\b0 \cf0 \ulnone For other changes in this release, see the 93\f2\i What's new 94\f0\i0 section in the {\field{\*\fldinst{HYPERLINK "https://www.python.org/doc/"}}{\fldrslt Documentation Set}} for this release and its 95\f2\i Release Notes 96\f0\i0 link at {\field{\*\fldinst{HYPERLINK "https://www.python.org/downloads/"}}{\fldrslt https://www.python.org/downloads/}}.\ 97}
