Caveats
-------
This is an alfa version, and for this once it really means that: there
are quite a few features that have only lightly been tested, and bugs are
to be expected.
This is a beta version, so use with caution.
Aside from the general Python 1.6 features like unicode support the
main new features of this MacPython release is support for multithreading.
This has had some preliminary testing, but please report any success or failure
on the mailing list.
Aside from the general new Python 2.0 features (compared to 1.5.2, there
was no 1.6 for the macintosh) like unicode support the main new features

some preliminary testing, but please report any success or failure on
the mailing list.
This installer installs MacPython for PowerPC only, whether a 68K distribution
of Python 1.6 will happen is not certain at the moment.
Changes since 1.6a1
-------------------
- All core-Python changes, plus a few from after 1.6a2, approximately as the
Python CVS tree was at May 5.
- The threading performance bug has been fixed.
- Tkinter is included again (yeah!), but only lightly tested. Please report
findings to the mailing list.
- macfsn.py is auto-imported on startup (unless disabled with a new option).
This retrofits macfs.StandardGetFile() and friends to use Navigation Services
in stead of the old Standard File dialogs.
- I think all installer problems have been fixed. Please report if not so.
This installer installs MacPython for PowerPC only, if you really want
68k support you will have to stay with 1.5.2. Or, if you are willing to
invest the time and have access to CodeWarrior you are welcome to try
and build a 68k distribution, most of the projects and sources are
reasonably up to date (May 2000). Contact me for details.
What to install
---------------
This installer is PPC only: too many new MacOS features are not available on 68K,
and doing workarounds, even just #ifdeffing in the code, is too much work for
me right now. If someone wants to revive 68K-MacPython: please do so. The project
files still contain the 68K targets (they're simply skipped by the build process)
so all that is needed is CodeWarrior, a source distribution and commitment.

After the installer finishes it automatically launches the

If you have previously installed another copy of 2.0b1 you should manually
remove your preference file first (but no such action is needed for installing
beside older MacPythons, and they will live together happily).

After installing
----------------
The first step thing you could try is to run "compileall.py" to create
all .pyc files, but this isn't very important, as pyc files are
created on-the-fly as well. You may also want to skip this step if you
are low on diskspace.
Next, it is probably a good idea to run the automatic tests. Start
Python and "import test.autotest". This should not print only one error, about some

Other mac-specific goodies can be found in :Mac:Tools, of which the IDE sources
and a CGI framework deserve special mention.

formats is included, but without documentation. You can find docs at
