Major new features of the 3.3 series, compared to 3.2

- PEP 380, syntax for delegating to a subgenerator (yield from)

- The import system (__import__) is based on importlib by default
- The new "lzma" module with LZMA/XZ support

- PEP 409, suppressing exception context
- PEP 414, explicit Unicode literals to help with porting
- PEP 418, extended platform-independent clocks in the "time" module
- PEP 412, a new key-sharing dictionary implementation that significantly saves memory for object-oriented code

- The new "ipaddress" module
- The "sys.implementation" attribute

|||The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).|
