[python-control-announce] python-control 0.10.0 released

[Richard M. <mu...@cd...>]

This release changes the interface for plotting to use a "response/plot" design pattern ([#920](https://github.com/python-control/python-control/pull/920), [#924](https://github.com/python-control/python-control/pull/924), [#953](https://github.com/python-control/python-control/pull/953)), adds multivariable interconnect functionality ([#881](https://github.com/python-control/python-control/pull/881)), restructures I/O system classes ([#916](https://github.com/python-control/python-control/pull/916)), and adds the norm() function to compute input/output system norms ([#971](https://github.com/python-control/python-control/pull/971)).  A number of other smaller enhancements, bug fixes, and updates to documentation and examples are also included.

**Note:** This release may break code that was using v0.9.4 or earlier.  In addition, the `matrix` class in NumPy is no longer supported, and Python 3.10 or higher is required.
