Der er ogs\u00e5 tilf\u00f8jet en ny JSON-dekoder, som er betydeligt hurtigere, bruger mindre hukommelse og er optimeret til JIT. Modulet CFFI 1.13 (C Foreign Function Interface) er blevet opdateret med en implementering af interface til kald af funktioner skrevet i C og C++. CFFI anbefales til interaktion med C-kode, mens cppyy anvendes til C++-kode. Modulet _ssl baseret p\u00e5 CFFI er blevet backportet til PyPy2.7.
