Python 3.4 doesn't have any new syntax features but it does have new and improved library modules, including one for a standard implementation of enumeration types.
Python 3.4 is the first big milestone since Python 3.3 Released in October 2012. Although it doesn't have have anything groundbreaking to offer there are lots of improvements that offer something for everyone.
As we reported last spring, the fact that Python 3.4 was going to include enum caused something of a stir among Pythonistas as they dredged up past history and debated whether comparing integers is semantically meaningful. Now 3.4 is here and it does include a standardized enum module.
Another noteworthy new module is asyncio which should be entirely uncontroversial as it provides the Asynchronous IO support that is so important to cloud developers.
A new palthlib module provides object-oriented filesystem paths; a new tracemalloc debug tool is provided for tracing memory blocks allocated by Python and there's a new hash algorithm for Python strings and binary data.
Other new modules provide for core statistics support in the standard library, for ensuring PIP is always available and that newly-created file descriptors are non-inheritable.
Python 3.4 also features various improvements to existing Python modules and includes a number of security enhancements.
