Python 3.5.0b1 was released on May 24th, 2015.
Major new features of the 3.5 series, compared to 3.4
Among the new major new features and changes in the 3.5 release series so far are
- PEP 448, additional unpacking generalizations
- PEP 461, adding support for "%-formatting" for bytes and bytearray objects
- PEP 465, a new operator (@) for matrix multiplication
- PEP 471, os.scandir(), a faster alternative to os.walk()

Python 3.5 has now entered "feature freeze". By default new features may no longer be added to Python 3.5. (However, there are a handful of features that weren't quite ready for Python 3.5.0 beta 1; these were granted exceptions to the freeze, and are scheduled to be added before beta 2.)
Notes on this release
- The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".) They will not work on Intel Itanium Processors (formerly "IA-64").
- Windows users: If installing Python 3.5.0b1 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
- Windows users: There are now "web-based" installers for Windows platforms; the installer does not contain Python, but instead downloads just the needed software at installation time.
- Windows users: The Windows binaries were built with Microsoft Visual Studio 2015, which is not yet officially released. (It's currently offered in "Preview" mode, which is akin to a "beta".) It is our intention to ship Python 3.5 using VS2015, although right now VS2015's final release date is unclear.
- OS X users: The OS X installers are now distributed as signed installer package files compatible with the OS X Gatekeeper security feature.
- OS X users: There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
