TODO: This is primarily a bug fix release. It also has a number of new features: The Nix language now supports floating point numbers. They are based on regular C++ float and compatible with existing integers and number-related operations. Export and import to and from JSON and XML works, too. All "chroot"-containing strings got renamed to "sandbox". In particular, some nix options got renamed, but the old names are still accepted as lower-priority aliases. This release has contributions from TODO.
