SciPy 1.0 was announced this morning. Ralf Gommers wrote:
A version number should reflect the maturity of a project - and SciPy was a mature and stable library that is heavily used in production settings for a long time already. From that perspective, the 1.0 version number is long overdue.
Some key project goals, both technical (e.g. Windows wheels and continuous integration) and organisational (a governance structure, code of conduct and a roadmap), have been achieved recently.
The code of conduct he mentions is here: https://github.com/scipy/scipy/blob/master/doc/source/dev/conduct/code_of_conduct.rst.
It's been interesting lurking in the code of conduct discussions on scipy-dev and on GitHub. The project used a few existing CoCs as starting points (including the Contributor Covenant used at Mapbox) and ended up with something they felt more suited to their community.
