**NEW* As of Python 3.4.0b1:
21+
22+
New Installation Options and Defaults
23+
=====================================
24+
25+
The Python installer now includes an option to automatically install
26+
or upgrade pip, a tool for installing and managing Python packages.
27+
This option is enabled by default and no Internet access is required.
28+
If you do want the installer to do this, select the "Customize" option
29+
at the "Installation Type" step and uncheck the "Install or ugprade
30+
pip" option.
31+
32+
To make it easier to use scripts installed by third-party Python
33+
packages, with pip or by other means, the "Shell profile updater"
34+
option is now enabled by default, as has been the case with Python
35+
2.7.x installers. You can also turn this option off by selecting
36+
"Customize" and unchecking the "Shell profile updater" option. You can
37+
also update your shell profile later by launching the "Update Shell
38+
Profile" command found in the /Applications/Python $VERSION folder. You may
39+
need to start a new terminal window for the changes to take effect.
40+
41+
Python.org Python $VERSION and 2.7.x versions can both be installed and
42+
will not conflict. Command names for Python 3 contain a 3 in them,
43+
python3 (or python$VERSION), idle3 (or idle$VERSION), pip3 (or pip$VERSION), etc.
44+
Python 2.7 command names contain a 2 or no digit: python2 (or
45+
python2.7 or python), idle2 (or idle2.7 or idle), etc. If you want to
46+
use pip with Python 2.7.x, you will need to download and install a
47+
separate copy of it from the Python Package Index
48+
(https://pypi.python.org/pypi).
