BTW, Windows Server 2003 has extended support until 14 July 2015. Will it be supported in Python 3.5?Windows XP goes EOL next month, so that will be dropped for 3.5 next year in accordance with PEP 11. However, Vista is still in extended support until 2017 - under the current PEP 11 guidelines, that means it will be supported for at least 3.5, and likely 3.6 as well.
