RELNOTES
Python 3000 Release Notes
=========================
Release notes describe unfinished work in particular releases.
Please report bugs to http://bugs.python.org/.
Version 3.0a2 - Release Date 07-Dec-2007
----------------------------------------
* The AMD64 Windows installer doesn't contain Tcl/Tk, and hence IDLE
won't work. This is because Tcl doesn't compile at all on this
platform.
* The 32bit build for the Win32/x86 platform is optimized with PGO
(profile guided optimization). Please read Microsoft's docs for
`PGO
<http://msdn2.microsoft.com/en-us/library/e7k32f4k(VS.90).aspx>`_
if you are interested in details. Preliminary benchmarks have shown
a speedup of about 10% in PyBench. Real world applications may gain
more or less speedup.
* The Tools directory contains a copy of the 2to3 conversion tool.
Note that 2to3 itself must be run with Python 2.5!
* SSL support is back! However, while the tests pass, the SSL code
appears to be leaking quite a bit, and there are still bugs.
We'll be working on this for the next release.
* On Windows, Python can't be run from a directory with non ASCII chars
in its path name (`bug #1342 <http://bugs.python.org/issue1342>`_).
* On Windows, the module doc server (pydocgui.pyw) is crashing.
* On Windows, the menus in IDLE are broken.
* The current releases of Cygwin and MinGW can't create extensions for
the official Python 3.0 binary. The necessary modifications to
Cygwin are already in its CVS. Look out for a new Cygwin release!
* Otherwise, the 3.0a1 release notes below still apply, except hashlib
no longer requires openssl, and IDLE now seems fine (except on Windows).
Version 3.0a1 - Release Date 31-Aug-2007
----------------------------------------
* SSL support is disabled. This causes test_ssl to be skipped.
The new SSL support in the 2.6 trunk (with server-side support and
certificate verification) will be ported for 3.0a2.
* If you don't have `openssl <http://www.openssl.org>`_ installed, or
a version older than 0.9.7, hashlib is non-functional, which means
there is no way to compute MD5 checksums. This breaks some modules.
* Platform support is reduced. We've mostly tested on Linux, OSX,
and Windows. Solaris is also supported (somewhat).
* There may be additional issues on 64-bit architectures.
* There are still some open issues on Windows.
* Some new features are very fresh, and probably contain bugs: the new
format() method on strings (PEP 3101), the strict separation of
bytes and strings, the new buffer API (PEP 3118).
* IDLE still has some open issues. If you can't run it at all, try
"idle -n" which disables the separate subprocess for the
interpreter.
