Die Ver\u00f6ffentlichung wurde gleichzeitig f\u00fcr die Versionen PyPy2.7 und PyPy3.6 vorbereitet, die die Syntax von Python 2.7 und Python 3.6 unterst\u00fctzen. Die Ver\u00f6ffentlichung ist f\u00fcr Linux (x86, x86_64, PPC64, s390x, Aarch64, ARMv6 oder ARMv7 mit VFPv3), macOS (x86_64), OpenBSD, FreeBSD und Windows (x86) verf\u00fcgbar. <\/p>\n<p>Ein besonderes Merkmal von PyPy ist die Verwendung eines JIT-Compilers, der zur Laufzeit einige Elemente in Maschinencode \u00fcbersetzt, was eine <noindex><a rel=\"nofollow\" href=\"http:\/\/speed.pypy.org\/\">hoch<\/a><\/noindex> Die Leistungsstufe \u2013 bei der Ausf\u00fchrung bestimmter Operationen \u00fcbertrifft PyPy die klassische Implementierung von Python in C (CPython) um ein Vielfaches.

Au\u00dferdem wurde ein neuer JSON-Dekoder hinzugef\u00fcgt, der deutlich schneller ist, weniger Speicher ben\u00f6tigt und f\u00fcr JIT optimiert wurde. Das CFFI-Modul 1.13 (C Foreign Function Interface) wurde aktualisiert, um eine Schnittstelle zum Aufrufen von Funktionen, die in C und C++ geschrieben sind, bereitzustellen. CFFI wird f\u00fcr die Interaktion mit C-Code empfohlen, w\u00e4hrend cppyy f\u00fcr C++-Code verwendet wird. In die PyPy2.7-Zweig wurde das _ssl-Modul basierend auf CFFI zur\u00fcckportiert.
