Python 3.5.0rc2

Python 3.5 has reached end-of-life. Python 3.5.10, the final release of the 3.5 series, is available here.

Among the new major new features and changes in the 3.5 release series are

  • PEP 441, improved Python zip application support
  • PEP 448, additional unpacking generalizations
  • PEP 461, "%-formatting" for bytes and bytearray objects
  • PEP 465, a new operator (@) for matrix multiplication
  • PEP 471, os.scandir(), a fast new directory traversal function
  • PEP 475, adding support for automatic retries of interrupted system calls
  • PEP 479, change StopIteration handling inside generators
  • PEP 484, the typing module, a new standard for type annotations
  • PEP 485, math.isclose(), a function for testing approximate equality

  • PEP 488, eliminating .pyo files
  • PEP 489, a new and improved mechanism for loading extension modules

Python 3.5 has now entered "feature freeze". By default new features may no longer be added to Python 3.5.

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 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 will download the needed software components at installation time. There are also zip files containing the Windows build making it easy to redistribute Python as part of another software package.
  • 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.
