============
PyPy3 v5.5.0
============

We're pleased to announce the release of PyPy3 v5.5.0. Coming four months 
after PyPy3.3 v5.2, it improves compatibility with Python 3.3 (3.3.5). We 
strongly recommend updating from previous PyPy3 versions.

We would like to thank all of the people who donated_ to the `py3k proposal`_
for supporting the work that went into this release.

You can download the PyPy3.3 v5.5.0 release here:

Highlights
==========

* Improved Python 3.3.5 support.

  - os.get_terminal_size(), time.monotonic(), str.casefold()

  - faulthandler module

  - There are still some `missing features`_ such as a
    `PEP 393-like space efficient string representation`_ and `known issues`_
    including performance regressions (e.g. issue `#2305`_). The focus for this
    release has been updating to 3.3 compatibility. Windows is also not yet
    supported.

* `ensurepip`_ is also included (it's only included in CPython 3 >= 3.4).

What is PyPy?
==============

PyPy is a very compliant Python interpreter, almost a drop-in replacement for
CPython 2.7.10 and 3.3.5. It's fast due to its integrated tracing JIT
compiler.

We also welcome developers of other `dynamic languages`_ to see what RPython
can do for them.

This release supports:

  * **x86** machines on most common operating systems except Windows
    (Linux 32/64, Mac OS X 64, OpenBSD, FreeBSD),

  * newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux,

  * big- and little-endian variants of **PPC64** running Linux,

  * **s390x** running Linux

Please try it out and let us know what you think. We welcome feedback, we know
you are using PyPy, please tell us about it!

Cheers

The PyPy Team
