For those who wish to try Python on the Mac, I've made a pre-release
version of 0.9.5 for the Mac available by anonymous ftp from site
ftp.cwi.nl, file /pub/Python0.9.5.hqx. This is just an application
binary; you will still have to fetch UNIX 0.9.4 distribution to get
the library modules.

Here's the list of changes in 0.9.5 compared to 0.9.4, insofar as they
are relevant to the Mac version:

Features:
- dictionary objects can now be compared properly; e.g., {}=={} is true
- new exception SystemExit causes termination if not caught;
it is raised by sys.exit() so that 'finally' clauses can clean up,
and it may even be caught. It does work interactively!
- new module "regex" interfaces to GNU Emacs regular expression;
old module "regexp" rewritten in Python for backward compatibility
- formal parameter lists may contain trailing commas

Bugs fixed:
- assigning to or deleting a list item with a negative index dumped core
- masking operations involving negative long integers gave wrong results

UNIX source will be made available soon.
