(New in 2.3a2.) range() - as of 2.3b1 supports long arguments with a magnitude larger than sys.maxint. E.g., range(2**100, 2*...

  • Notes

    ...inter member ob_sinterned has been replaced by an int member ob_sstate. On some platforms (e.g. most 64-bit systems) this may change the offset of the ob_sval member, so as a precaution the API_VERSION has been incremented. The apparently unused feature of "indirect interned strings", supported by the ob_sinterned member, is gone. Interned strings are now usually mortal; there is a new API, PyString_InternImmortal() that creates immortal interned strings. (The ob_sstate member can o...

  • Python 2.4.1 - Release Notes

    ...InternalCall(). It is still the case that the returned code object might be entirely insane. Subclasses of string can no longer be interned. The semantics of interning were not clear here -- a subclass could be mutable, for example -- and had bugs. Explicitly interning a subclass of string via intern() will raise a TypeError. Internal operations that attempt to intern a string subclass will have no effect. Bug 1003935: xrange() could report bogus OverflowErrors. Documented what xrange() in...
