Still much to do before 3.0 finally release. Slow and steady wins the race. What's New in Python 3.0 release candiate 3? ============================================ *Release date: 20-Nov-2008* Core and Builtins ----------------- - Issue #4349: sys.path included a non-existent platform directory because of a faulty Makefile. - Issue #3327: Don't overallocate in the modules_by_index list. - Issue #1721812: Binary set operations and copy() returned the input type instead of the appropriate base type. This was incorrect because set subclasses would be created without their __init__() method being called. The corrected behavior brings sets into line with lists and dicts. - Issue #4296: Fix PyObject_RichCompareBool so that "x in [x]" evaluates to True, even when x doesn't compare equal to itself. This was a regression from 2.6. - Issue #3705: Command-line arguments were not correctly decoded when the terminal does not use UTF8. Library ------- - Issue #3799: Fix dbm.dumb to accept strings as well as bytes for keys. String keys are now written out in UTF-8. - Issue #4338: Fix distutils upload command. - Issue #4354: Fix distutils register command. - Issue #4116: Resolve member name conflict in ScrolledCanvas.__init__. - Issue #4307: The named tuple that ``inspect.getfullargspec()`` returns now uses ``kwonlydefaults`` instead of ``kwdefaults``. - Issue #4298: Fix a segfault when pickle.loads is passed a ill-formed input. - Issue #4283: Fix a left-over "iteritems" call in distutils. Build ----- - Issue #4289: Remove Cancel button from AdvancedDlg. - Issue #1656675: Register a drop handler for .py* files on Windows. Tools/Demos ----------- - Demos of the socketserver module now work with Python 3.

这是好事吧。一旦release，几年之内都要维护compatibility。更不用说Python没有标准，发布的程序是什么，Python语言就是什么。不像C/C++/C#，还有ISO来制定标准。【在 yegle 的大作中提到: 】 : 昂？还没final release啊…

没有。情况和Python差不多，想怎么改就怎么改，想加什么功能就加什么功能。【在 yegle 的大作中提到: 】 : java有iso标准不？

java好像就sun公司出了个标准，但是没多少人认真听他们的【在 yegle (一阁@SL小分队@lp是大牛) 的大作中提到: 】 : java有iso标准不？

？标准怎么了？标准是为了开发语言用的。 java语言现在也就sun还有gcc两个在开发，需要很多人听么？

各有各的好处吧。 Python拒绝制定标准的理由就是想要不断“进化”语言来满足越来越多的需要。但是没有标准也就意味着不同的实现之间的兼容性将是个问题。

挖坟。现在，在oracle起诉google的背景下，看到这句话觉得百感交集。【在 IkariShinji 的大作中提到: 】 : java好像就sun公司出了个标准，但是没多少人认真听他们的 : 【在 yegle (一阁@SL小分队@lp是大牛) 的大作中提到: 】 : : java有iso标准不？ : ...................
