Python 3.6.9. On 24 December 2019, version 7.3 was released, with support for Python 3.6.9. On 16 February 2020, the PyPy team announced the move of the source code hosting from Bitbucket to heptapod.net with the repositories of the CFFI (C Foreign Function Interface) project. A new logo and website design are also published. However, the author and the license of the new logo are unknown. Funding PyPy was funded by the European Union being a Specific Targeted Research Project between December 2004 and March 2007. In June 2008, PyPy announced funding being part of the Google Open Source programs and has agreed to focus on making PyPy more compatible with CPython. In 2009 Eurostars, a European Union funding agency specially focused on SMEs, accepted a proposal from PyPy project members titled "PYJIT – a fast and flexible toolkit for dynamic programming languages based on PyPy". Eurostars funding lasted until August 2011. At PyCon US 2011, the Python Software Foundation provided a $10,000 grant for PyPy to continue work on performance and compatibility with newer versions of the language. The port to ARM architecture was sponsored in part by the Raspberry Pi Foundation. The PyPy project also accepts donations through its status blog pages. As of 2013, a variety of sub-projects had funding: Python 3 version compatibility, built-in optimized NumPy support for numerical calculations and software transactional memory support to allow better parallelism.
