Python 3: the Next Generation (is here already)
summary
Python 3 has been shipping since December 2008 and makes concrete, breaking changes: print()->function, unicode by default with a new bytes/bytearray type, true division by default, unified int/long, and iterator-returning built-ins (map/filter/range and dict view methods). Migration tooling exists: the 2to3 tool, a -3 warning switch, and many 3.x features backported to 2.6/2.7. Early 3.0 performance trails 2.6 but improves in 3.1/3.2; package adoption grows (≈350 then +100 in three months).
