The epoch-changing version 4.0.0 will include the following:

• Any refactoring to the use of dask that has become apparent from its use from version 3.14.0 onwards (none yet, as of January 2024).
• Changes to method/attribute names to improve consistency and make them more intuitive.
• Backwards incompatible API changes to make cf more in line with the Python array API standard (https://data-apis.org/array-api/latest/).
