| Python 3000 Release Notes |
| ========================= |
| |
| Release notes describe unfinished work in particular releases. |
| |
| Please report bugs to http://bugs.python.org/. |
| |
| |
| Version 3.0a5 - Release Date 08-May-2008 |
| ---------------------------------------- |
| |
| Please search the bug tracker for critical issues in Python 3.0. |
| |
| |
| 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. |
