Hy 1.0.0 has been released after 12 years of development. This Lisp dialect embedded in Python can be found at Hylang.org. The NEWS file offers a detailed version history, while the HYPE POST provides a less serious take on things. Moving forward, major version number increases will signify breaking changes to documented parts of the language. The focus will be on bug fixes, compatibility with new Python versions, and support for new Python features without breaking code that works on previous Hy 1.x.y versions.
