Python 3.0 Release Notes
|
|
========================
|
|
|
|
These release notes describe unfinished work, or important notes that Python
|
|
3.0 adopters need to be aware of. This is not a complete list of changes for
|
|
Python 3.0 -- for that, see Misc/NEWS.
|
|
|
|
Please report bugs to http://bugs.python.org/.
|
|
|
|
Version 3.0rc1 - Release Date XX-Sep-2008
|
|
-----------------------------------------
|
|
|
|
* The bsddb3 package has been removed from the standard library. It is
|
|
available as a separate distutils based package from the Python Cheeseshop.
|
|
If you need bsddb3 support in Python 3.0, you can find it here:
|
|
|
|
http://pypi.python.org/pypi/bsddb3
|
|
|
|
|
|
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.
