v2.0.0

ctrl-VQE with a more modular and intuitive interface for implementing new device and drive types, including those in which the drives are coupled to the same device parameters.

v1.1.0

Adds the modulars framework for more easily managing devices and energy functions.

Also includes some breaking changes to the Devices interface (certain minor functions removed and whatnot).
Most significantly, Parameters.bind has been re-christened Parameters.bind!. (Properly this ought to be a 2.0 but I'm saving that elegant-sounding name for the next release.)

Note that documentation and testing are rather out of date. Use at your own risk. Absolutely not supported.

v1.0.0

This version is stable and well-used for single-qubit drives, parameters local to a single drive, and fixed frequencies.

It is also compatible, though inconvenient, with multi-qubit drives and coupled signals. Making these use-cases more convenient, and allowing for time-varying frequencies, will involve breaking changes, necessitating proper semantic versioning.
